Diesel-like fuel was produced from waste minerals and tire oils by pyrolytic distillation. Among these produced fuels, the sulfur rate in DL-MF (Diesel-like mineral fuel) is within the limits of DF, and in DL-TF (Diesel-like tire fuel), due to the high sulfur rate, the sulfur removal process is carried out by applying 10% perlite, 10% CaO, and 10% zeolite catalysts. Then, these two fuels were modeled with ANN based on the experimental results obtained from running an IC engine with a blend of DF in different proportions at a constant rpm and different loads. The performance, combustion, and emission values were examined, and in the combustion parameter, calculations with model application for MGT, CHR, NHRR, RPR, and CP for each ANN prediction could be made. In ANN modeling, the network was trained with 10 neurons using feed-forward experimental data. The best R2 estimation of CGP followed values: 0.99998 with DLTF30-5 bar Bmep and 0.99989 with DLMF30-2.5 bar Bmep. It has been found that the parameters in the experimental data match well with the robust values predicted by the ANN determined in the network test data.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148079838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of the packed bed adsorber requires technical data on the phenol-AC interaction. By utilizing information on the breakthrough performance of the laboratory-scale fixed bed column derived from appropriate kinetic models, applicable scale-up design protocols were then employed. It was found that the column breakthrough time increased with increasing AC bed height and increasing phenol concentration, but decreased with increasing flowrate. The bed adsorption capacity increased with bed height, achieving a maximum of 0.316 mg/g at 50% breakthrough, which occurred at 19.25 min. For the scale-up, an adsorber of diameter 0.5 m and AC bed height of 1.7 m would be required to treat 1000 US gal/day of 2 mg/L phenol-contaminated water. This bed height is equivalent to 219.44 kg of AC, which is produced from 1065 kg of coconut shells. This study showed that a sustainable waste management system to alleviate disposal challenges associated with produced water and the coconut industry could be implemented using the packed bed adsorber technology.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148084516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to previous studies, NH3 was chosen as the gaseous pollutant, and a series of numerical simulations were conducted. The results demonstrate that the airflow within the water pipeline is piston flow, the direction of which is determined by ventilation mode. Affected by the Coanda effect, the ununiform velocity leads to an uneven distribution of NH3 on the water pipeline cross-sections. The mean cross-sectional values are chosen for further analysis. The concentration of NH3 in the water pipeline is proportional to the release rate of NH3 and distance to the air inlet vent, respectively. When the release rate is fixed, increasing the ventilation velocity can effectively remove the pollutant, and the concentration of NH3 is proportional to the −1 power of the ventilation velocity. Finally, a prediction model of the mean cross-sectional concentration of NH3 is obtained by combining it with theoretical analysis. Therefore, this study can not only optimize the operation of the ventilation system in this Inter-basin Water Transfer (IBWT) project but also guide the design of the ventilation system in other IBWT projects with deep buried long-distance water pipelines.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148071586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ethanol can be produced from a wide range of feedstocks, which are classified into three generations based on their source, composition, and sustainability. Emerging feedstock's waste fruits and vegetables (e.g., overripe bananas, spoiled potatoes) can also be used. This study focuses on producing ethanol from overripe banana fruits by direct sugar fermentation and distillation since Tamil Nadu and Andhra Pradesh contribute 30% of India's banana production. Hence, the selection of bananas is an economical and practical feedstock. This study also evaluates the performance, combustion, and emission characteristics of a single-cylinder, four-stroke, and Open Engine Control Unit (ECU) SI engine using prepared ethanol and petrol blends, ranging from E5 to E10. The results show that the performance and combustion characteristics of engines fuelled by E10 blend fuel were closer to petrol operation and a drastic reduction in emissions.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148073949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments are performed in a single-cylinder, 4-stroke water-cooled diesel engine under variable engine loads (0, 4, 8, 12, and 16 N) with a constant speed of 1500 rpm (compression ratio of 18:1). Three WCVOs (Ground nut, Palm, and Sunflower) in volumes of 20% each along with n-butanol at 10% and diesel at 70% are considered for the analysis. The diesel engine adjusts the EGR at 15% and 25%. For these cases, performance features such as brake thermal efficiency (BTE), brake-specific fuel consumption, brake-specific energy consumption, and exhaust gas temperature are evaluated. The BTE was observed to decrease with the WCVO blends due to their higher oxygen content and lower calorific value. The BTE value is also increased for the Palm WCVO at the 15% EGR with the increase in engine load. The emission parameters like nitrogen oxides (NOx), carbon monoxide, carbon dioxide, oxygen, and smoke opacity are also tracked, and it was found that the NOx and particulate matter inside the engine cylinder are reduced using the EGR. For all loads, the Sunflower (20%) with 15% EGR reduces the NOx by 5%–10% compared to diesel. The combustion parameters, like cylinder pressure and heat release rate, are also analyzed for all fuel blends.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148083674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural analysis confirmed high crystallinity of TiO2 by 16.26 nm and Al2O3 by 15.65 nm. Test blends were prepared by enriching a baseline 20% silkworm biodiesel-diesel blend (S20) with TiO2 and Al2O3 nanoparticles at 50 and 100 ppm (S20T50, S20T100, S20A50 and S20A100). Among the tested fuels, the S20T100 blend showed better performance than neat diesel and other test fuels. Combustion analysis indicated that S20T100 reached a peak in-cylinder pressure of 67 bar and heat release rate of 49 J/CAD, corresponding to increases of 31% and 16% over diesel. In terms of emissions, S20T100 reduced UBHC from 78 ppm to 68 ppm, lowered CO from 0.597% to 0.43%, representing a 28% reduction and decreased smoke opacity by 3.5% compared to diesel. Nitrogen oxide emissions for S20T100 were 1020 ppm, slightly lower than diesel at 1087 ppm and remained lower than those of the base S20 biodiesel blend. These results indicate that the S20T100 blend of silkworm biodiesel enriched with TiO2 nanoparticles improves fuel efficiency and reduces pollutant emissions, offering a sustainable and cleaner alternative to conventional diesel without any engine modifications.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148100541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically investigates the pollution characteristics of heavy metals and PAHs in these coking solid wastes. The results indicate that the different kinds of coking solid wastes have irregular shapes with small amounts of micropores on the particle surfaces. The different kinds of coking solid wastes contain varying amounts of heavy metals, including As, Zn, Cu, Cr, Ni, and Cd; and the ecological risk of heavy metals is TR > CS > CP > OS. In contrast, the pollution characteristic of PAHs in coking solid wastes is more serious than that of heavy metals; 16 kinds of PAHs with controlled priority of US Environmental Protection Agency are detected in the different kinds of coking solid wastes, especially about 2–3 ring compounds; the ecotoxicity and carcinogenicity of coking solid wastes correspond to the levels of ∑PAHs in coking solid wastes.

This review provides a systematic overview of dust removal technologies targeting PM2.5 and PM1. It covers traditional dry dust removal methods, including electrostatic precipitators (ESPs), baghouse filters, and cyclone separators, as well as new ESP-based integrated technologies, such as wet electrostatic precipitators (WESPs), ESP-baghouse hybrids (EFF), and low-low-temperature ESPs (LLT-ESP). The review separately compares the differences in efficiency and economic feasibility among various traditional technologies and among various novel integrated technologies, and highlights key strategies for improving removal efficiency, such as particle agglomeration, structural optimization, and material enhancement. Analysis shows that integrated technologies can achieve ultra-low emissions (<5 mg·m−3), but their complex structures and high investment and maintenance costs limit large-scale application. Developing technologies that balance high efficiency, and low cost remains a key challenge. In addition, this review highlights the methods and challenges of ultrafine particle resource utilization. These topics have been rarely addressed in previous reviews. More importantly, this study emphasizes the key role of intelligent control in achieving high efficiency, low cost, and ultra-low emissions in coal-fired power plants. It underlines the value of intelligent control for next-generation purification systems. The review also provides theoretical guidance for future technology development and engineering applications.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148098636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
