A novel fractional acid hydrolysis technology was demonstrated in this study, which produced more than 90 % (w/w) of available glucose in wheat straw as glucose-rich hydrolysate (GRH). This hydrolysate was then made acid-free using a membrane-based acid separation unit to reuse the separated acid to make the hydrolysis process environmentally safe and chemically inexpensive. Thereafter, this acid-free GRH was fermented to bioethanol using a unique constant volume fed-batch fermentation technique under an optimum glucose-feeding strategy. Remarkably, this fermentation technique yielded optimal average bioethanol productivity (g/Lh), yield (g/g), and titer (g/L) of 7.147±0.533, 0.508±0.002, and 58.835±0.766; 5.722±0.529, 0.501±0.006, and 33.748±0.322, respectively, with more than 99 % glucose utilization during ten fed-batch cycles of synthetic and GRH glucose.

The hydration mechanism of the chosen typical mixtures is analyzed via X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy, and the results show that a needle-like Aft gel, identified as the major gelatinous product, is intricately intertwined to create an intricate network structure.

However, the industrial feasibility of employing deep eutectic solvents (DESs) for pretreatment of microalgae remains a relatively uncharted territory, which had been acknowledged as a noteworthy research gap in the literature. The purpose of the article is to develop life cycle and energetic analyzes of a co-production (biogas&amp; biodiesel) plant under a microalgae-to-biofuel process. The proposed biofuel production process is based on a hydrothermal disintegration (HD)/DES cycle. An in-depth analysis and comparison between HD/DES of microalgae for the concurrent production and the conventional HD process is developed. Additionally, the effectiveness of recrystallization and membrane filtration for DES recovery was developed. Finally, the sensitivity analyses, focusing on variables like lipid recovery, DES usage quantity, the efficiency of DES recovery, and biogas yield, are provided. When compared to traditional HD, the incorporation of DES during HD led to a substantial 36.8 % improvement in energy output. However, this came at the cost of higher energy input, resulting in a rise in ratio of net energy by 28 %, primarily due to the energy-intensive nature of DES synthesis. Additionally, the introduction of DES contributed to a slight increase in overall released GHG, from −25.86–25.72 g CO₂ (eq.) per MJ. Notably, a combination approach involving both membrane filtration and recrystallization yielded promising results, achieving a low ratio of net energy of 0.46 and even negative overall released GHG. The sensitivity analyses findings emphasized the need for reducing energy utilization in DES synthesis and addressing more energy-efficient recovery processes to further enhance the HD/DES process's environmental performance and energy efficiency. This study provides valuable insights into optimizing the co-production plant under a microalgae-to-biofuel process through HD/DES, highlighting avenues for sustainability improvements in this promising approach.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"193 ","pages":"Pages 54-73"},"PeriodicalIF":6.9,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142643120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 evaluates the effects of MW at different temperatures (20°C, 30°C, and 40°C) and pH levels (3, 5, and 7) on HPG-backfill’s mechanical strength. A comprehensive analysis, including uniaxial compressive strength (UCS) testing, scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric and differential thermogravimetric (TG-DTG), and nuclear magnetic resonance (NMR), was employed to explore degradation mechanisms. The results indicate a significant decline in the mechanical performance of HPG-backfill when exposed to MW. This degradation becomes particularly pronounced under more acidic conditions and at elevated temperatures. A polynomial relationship between strength and pH, and a linear correlation with temperature, were identified. Interaction effects between temperature and pH on 28-day strength degradation were observed, diminishing with increased temperature or decreased pH. Gray relational analysis highlights pH as a more critical factor than temperature in degradation. Strength degradation is primarily attributed to gypsum dissolution and the pressure induced by recrystallization, which leads to the formation of fatigue cracks. Additionally, acidic conditions accelerate premature crystallization, altering both the crystal morphology and the pore structure. These insights advance the understanding of HPG-backfill degradation, guiding the developing of more resilient backfill materials for extreme mining environments.","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"255 1","pages":""},"PeriodicalIF":7.8,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142691103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
