A mini review on biotransformation of coal to methane by enhancement of chemical pretreatment

Dan Zhang et al.

Summary: Coalbed methane (CBM) has significant environmental and economic value in addition to energy content. Chemical pretreatment of coal can enhance bioconversion rate and promote further development of CBM resources.

Experimental study of advantages of coalbed gas bioengineering

Xianbo Su et al.

Summary: Coalbed gas bioengineering (CGB) is a fermentation engineering that converts organic components of coal to methane, enhancing coalbed gas production. Laboratory simulations using different rank coals showed that all ranks of coal have potential for biomethane production. The bioconversion process also enhanced coal seam desorption capacity for methane and increased coal permeability.

Biodegradation of coal organic matter associated with the generation of secondary biogenic gas in the Huaibei Coalfield

Zhao Lu et al.

Summary: In this study, the compositional characteristics of saturated hydrocarbons and aromatic hydrocarbons in coal and coal-measure mudstone were analyzed to investigate their biodegradation characteristics and impact on secondary biogenic gas (SBG) enrichment. The research found that saturated hydrocarbons and aromatic hydrocarbons experienced different degrees of biodegradation, with varying levels of degradation observed.

Contemporary trends in composite Ni-based catalysts for CO2 reforming of methane

Mohammad Yusuf et al.

Summary: Converting greenhouse gases into valuable syngas through catalytic dry reforming of methane (DRM) is a viable solution, with Ni-based catalysts being extensively used and tested. The main limitation lies in catalyst deactivation due to carbon formation and sintering. Current research focus is on composite catalysts and density functional theory modeling for designing an ideal catalyst.

Effects of endogenous and exogenous dissolved organic matter on sorption behaviors of bisphenol A onto soils

Limei Mo et al.

Summary: The transport of organic contaminants in groundwater can be significantly influenced by the presence of dissolved organic matter (DOM) from various sources. This study investigated the impact of endogenous and exogenous DOM (referred to as DOMen and DOMex) on the sorption behavior of bisphenol A (BPA) onto two different soils. The results revealed that soil organic matter content and DOM properties played key roles in BPA sorption onto soils. Additionally, the presence of DOMen affected BPA sorption differently in the two soils due to differences in their inorganic components.
