The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

Spatio-temporal evolution of temperature fields in tar-rich coal and overlying strata during pyrolysis

Meitan kexue jishu
In-situ pyrolysis of tar-rich coal is an innovative coal utilization method that heats coal seams by isolating air to extract oil and gas resources. This approach plays a crucial role in improving domestic oil and gas supply and ensuring national energy ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Utilization of fruit waste for H2-rich syngas production via steam co-gasification with brown coal

Carbon Resources Conversion, 2023
In this work, to efficiently utilize waste fruit and low-rank coal for the hydrogen (H2)-rich syngas production, steam co-gasification of banana peel (BP) and brown coal (BC) was studied in a fixed-bed reactor.

Effect of Binder on Physical Properties of Extruded Activated Carbon and Its Application to Levofloxacin Adsorption

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Bamboo charcoal–based extruded activated carbons were prepared via molding, pre‐oxidation, carbonization, and steam activation, with coal tar, phenolic resin, and their mixtures employed as binders based on practical availability and technical feasibility. This study focused on the regulatory effects of binders on the mechanical properties and

In-situ pyrolysis mining theory and technical conception of controllable and spontaneous combustion of tar-rich coal

Meitan xuebao
As a strategic coal-based oil and gas resource, tar-rich coal is abundant in China. The development of oil and gas resources rich in oil and coal is of great strategic value to ensure China’s energy security and help the “double carbon” goal and energy ...

Chemical characterization of liquefaction products of an inertinite enriched northern Alaska coals [PDF]

, 1989
A Northern Alaskan coal rich in inertinites was further enriched by density gradient separations. The degree of condensation of the enriched coal was estimated to be low, mainly 3 ring.

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...
