The present status of the research and development in catalytic coal gasification was overviewed. First, the strategy for process design was examined from chemical viewpoints: equilibrium, kinetics, and thermal balance. This examination clarified that the usefulness of catalyst application was limitted to only certain steps among many reactions ...

A single‐lineage series of CO2‐activated carbons reveals how surface area, pore architecture, and defect density govern near‐neutral Zn–air battery cathodes. Moderate activation at 75% burn‐off balances energy efficiency and cyclability, whereas deeper activation increases power through mesopore formation but compromises durability. Zinc–air batteries (

Numerical simulation of crushed coal pressurized slagging gasification
The Crushed Coal Pressurized Slagging Gasification (British Gas-Lurgi, BGL) renders the use of gates obsolete and changes from dry slag discharge to liquid slag discharge, significantly improving the gasification performance.

Gasification Kinetics of Bituminous Coal Char in the Mixture of CO2, H2O, CO, and H2
The gasification kinetics of bituminous coal char was investigated in a mixture of CO2, H2O, CO, H2, and N2 under isothermal conditions. In addition, the impacts of gasification temperature, gasification time, and gas composition on the gasification ...

Structure‐Sensitive Steam Reforming of Methane Over Exsolved NiAl‐Layered Double Hydroxides
Exsolution of Ni nanoparticles from NiAl‐layered double hydroxides (LDH) provides a route to systematically control nanoparticle size in Ni/Al2O3 catalysts over the range of 4–18 nm. Methane steam reforming shows strong structure sensitivity, being favored over smaller (<10 nm) particles with 80 % methane conversion and a high specific hydrogen ...

Greenhouse Gas Reduction Potential Through Bioheat for Remote Communities in Northeastern Ontario
Heating infrastructure in remote areas has high potential for fuel switching, possibly leading to decreased greenhouse gas emissions. Using a simplified life cycle analysis approach, we show that woody residues from the forest industry have the potential to reduce greenhouse gas emissions compared to commonly used fossil fuels.
