Catalytic coal gasification:mechanism,kinetics,and reactor model

扫码查看
Catalytic coal gasification is a promising technology in the field of clean coal utilization.A comprehensive understanding of mechanisms,reaction kinetic,and reactor model is crucial.This article summarizes and analyzes the catalytic mechanisms of key reactions,such as C-O2,C-CO2,C-H2O,and CO-H2.It also compares various kinetic models,including shrinking core model,random pore model,volume model and their respective modifications.Additionally,the article delves into math-ematical modellings of catalytic coal gasification,encompassing molecular models or density functional theory,empirical model,computational fluid dynamics,Aspen modeling,and artificial neural network.The aim is to provide a roadmap for the development and scale up of reactors used in catalytic coal gasification.
