摘要

Abstract

This study investigates catalytic tar cracking over semi-coke catalysts

addressing reaction kinetics challenges by integrating experimental data with a COMSOL Multiphysics model. A multi-physics framework combines catalysis

carbon deposition

and self-consumption to analyze toluene (tar model compound) removal. The model evaluates intrinsic catalytic activity

porosity evolution

and porous media flow

revealing that toluene conversion is governed by diffusion/convective mass transfer

homogeneous reactions

and surface reactions influenced by dynamic carbon deposition/removal. Increasing temperature from 973 to 1173 K enhances gas-film heat and mass transfer coefficient

accelerating tar cracking rates and extending catalyst lifetime. Elevated temperatures improve gas-solid phase heat/mass transfer

promoting efficient tar removal during syngas purification. The results highlight the interplay between reaction kinetics

carbon deposition dynamics

and transport phenomena in optimizing semi-coke catalyst performance under high-temperature conditions.
