This research aimed to develop a new method for clean utilization and treatment of landfill leachate solid waste weathered coal. Landfill coal were adopted combined anaerobic fermentation methane production. The characteristics microbial community, mechanism biological production, broth residue co-fermentation analyzed through metagenomics, soluble organic matter detection thermogravimetric (TG) analysis. obtained results revealed that increased production by 80.1%. Syntrophomonas,...
Understanding the bioconversion process of lignite to methane is an important contribution establishment effective utilization existing coal resources and acquisition environmental biofuels. Microorganisms from seams were acclimatized using as sole carbon source improve bioavailability coal. The acclimation biomethanation was discussed aspects mathematical models, changes key intermediates in liquid phase, dynamic evolution community structure. results showed that anaerobic digestion (AD)...
Waste reuse energy generation is encouraged in many countries. A low H/C ratio coal a limiting factor that affects biomethanation. However, corn straw has better ratio, which beneficial to methane production. series of biological gas production experiments was carried out using lignite B, bituminous D, C, and study the effect synergistic biodegradation combined with into biomethane. Methane used as an index analyze characteristics single coal, straw, straw. The results show optimum...
The existing reservoir stimulating technologies are only applicable to hard coal but helpless for soft coal, which is one of the main factors hindering CBM industrialization in China. Therefore, it urgent develop a universal technology can increase permeability various reservoirs. Theoretical analysis and field tests were used systematically analyze mechanical mechanisms causing formation levels types fractures, such as radial tensile peripheral shear fractures hydraulic fracturing, reveal...
Lignite resource is abundant in China. Its high moisture and self-ignition tendency have limited its utilization as a fuel. Preparing humic acids considered to be an economic choice for the of lignite. Herein regenerated (RHAs) been obtained by means hydrolysis Chinese-aged lignite with NaOH catalyst. It has verified that hydrothermal process enabled 67% increase extraction yield (HAs). Moreover, RHAs, original (OHAs) commercial (CHAs) were characterized UV-Vis, acid functional groups...
