二氧化碳重整甲烷过程中催化剂积炭现象的探讨

A REVIEW OF CARBON DEPOSITE ON THE SURFACE OF CATALYST FOR CH_4 REFORMING WITH CO_2

二氧化碳重整甲烷制合成气的研究已逐渐成为国内外催化界研究的热点，由于二氧化碳和甲烷的分子结构及其反应特点，决定了该体系必然存在严重的积炭问题。本文对近年来在二氧化碳重建甲烷反应中有关积炭方面的研究结果进行了综述，其中包括：形成积炭的原因及抑制积炭的工艺条件选择、催化剂的设计、CO2和CH4的活化过程及反应机理等。

CO2 reforming of CH4 has obvious advantages over the steam re forming. But in this process carbon deposite is serious- So,how to fully use raw ma-terials and effectively control carbon deposite produced is important for developing CO, chemical industry. Here some operating conditions on carbon deposite,such as temperature,feed ratio,catalyst etc. and reaction mechanism is reviewed in detail.
