The result shows that: The mechanism of CO₂ imbibition can be divided into two aspects, one is the mutual solubility of oil and gas, the other is the competitive adsorption of oil and gas. From the molecular scale perspective, the imbibition process can be divided into three stages, in the early stage of rapid imbibition, the mixed-wetting surface has a weaker ability to attract CO₂, CO₂ is mainly miscible with the oil phase, resulting in the volume expansion of crude oil, which reduces the viscosity of crude oil, increases the fluidity of crude oil. In the intermediate transition stage, the interaction energy between CO₂ and the surface is 1.88 times that between the oil phase and the surface, CO₂ has an advantage in the competitive adsorption process with the oil phase, and has the ability to imbibe and replace more oil phase. In the later stable stage, the imbibition process roughly ends and the imbibition efficiency no longer increases. The imbibition efficiency of CO₂ first increases and then decreases with the increase of pressure and temperature. It is further found that the water-wetting part of the mixed-wetting surface can inhibit the attraction of the oil molecules in the oil-wetting part, improve the stripping ability of CO₂ to the residual oil adsorbed on the oil-wetting surface, so as to improve the imbibition efficiency.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"381 ","pages":"Article 133592"},"PeriodicalIF":6.7,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the lean coal in central and southern region of Henan, China with abnormal ground temperature was used as the substrate, and the microorganisms in coal seam water were used as the source of bacteria. The experiments were carried out at 50 °C, 55 °C, 60 °C, 65 °C and 70 °C, respectively. The results showed that hydrogenotrophic methanogenesis was the primary pathway of methane generation by thermophilic anaerobic digestion of coal. The hydrolysis products were consumed by hydrolysis bacteria <em>Coprothermobacter</em>, <em>Acetomicrobium</em> and acetic acid oxidizing bacteria <em>Tepidanaerobacter</em> to produce a large amount of H₂ and CO₂. Then CO₂ was reduced to CH₄ by the hydrogenotrophic methanogen <em>Methanothermobacter</em>. From all aspects, 55 °C was the most suitable for coal thermophilic anaerobic digestion to produce methane. At this temperature, the biomethane production at the peak of biogas production could reach 0.45 mL/g, and the cumulative production was 1.81 mL/g. The content of glycosyl transferases (GTs) was found to be the lowest in the anaerobic digestion system operating at 50 °C, resulting in the lowest coal degradation rate. In the 60 °C and 65 °C systems, cellular processes and the utilization of organic compounds exhibited lower activity compared to the 55 °C system, resulting in reduced methane production. Pyruvate metabolism and glycine metabolism were strongest at 70 °C, which could easily lead to acid accumulation and ammonia inhibition. The comprehension of this concept will establish a foundation for mitigating detrimental factors during the implementation process of Coalbed Gas Bioengineering under elevated temperatures.</div></div>","PeriodicalId":325,"journal":{"name":"Fuel","volume":"381 ","pages":"Article 133730"},"PeriodicalIF":6.7,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rare earth element (REE)-rich DPB can be converted to biochar via a direct pyrolysis approach, yet the efficacy of REE-biochar in the HSAD process remains unclear. Here, three types of REE-biochars (B300, B500 and B800) were produced at 300, 500 and 800 °C. The results showed that elevating pyrolysis temperature improved the REE-biochar properties such as specific surface area (SSA), electrical conductivity (EC), REE content, and graphitization degree, but reduced its electron exchange capacity (EEC). Compared to B300 and B500, the B800 addition clearly boosted methane yield (up to 60% and 29%) and maximum methane production rate (up to 21% and 15%). Microbial analysis showed that B800 not only enriched the acidogenic bacteria (e.g., <em>Ruminofilibacter</em>) and electroactive microbes (e.g., DMER64 and <em>Syntrophus</em>) but also enhanced microbial metabolisms and electron transfer ability. Further analysis showed that B800 facilitated methanogenesis probably by coordinating the interaction of key genera through quorum sensing system and modulating electron transfer through its intrinsic graphitic matrices and REE oxides.

Optimal liquid water removal occurred at intrinsic contact angles between 120°-140°. Angles below this range impede droplet detachment in the GC, while angles above it result in water accumulation within the GDL.

Techno-economic assessment of the process was further performed in the Chinese context. The route primarily included a first step of bioethanol production from bioconversion of biomass and a second step of hydrocarbon fuel production from aqueous ethanol by C–C coupling followed by hydrodeoxygenation (HDO). Two Cases were considered, in which wheat straw (WS, Case I) and industrial cellulosic residue (ICR, Case II) were employed as feedstock, respectively. As revealed by the assessment results, the consumption of biomass feedstock is 7.2 tonnes WS (5 % moisture content) or 16.0 tonnes ICR (45 % moisture content)/tonne bio-jet fuel for Case I and II processes, respectively. For a plant with an annual capacity of ∼20,000 tonnes bio-jet fuel, a total capital investment of 382 MM CNY is needed for Case I project, while 368 MM CNY needed for Case II project. The minimal selling prices (MSPs) of the bio-jet fuel to achieve zero net present value (NPV = 0) at a discount rate of 10 % are 12,258 CNY/tonne and 8952 CNY/tonne for Case I and II processes, respectively. The price of WS or ICR is the most sensitive factor affecting the MSP. For Case II project, the selling price of by-product steam also shows very significant impact on the MSP. Monte-Carlo simulation for risk analysis suggests that there is a high probability (96.66 %) for Case I plant to be profitable, while the probability of Case II plant is even as high as 99.99 % at the current price of bio-jet fuel (15,000 CNY/tonne).
