摘要
The clean and efficient utilization of low rank coal is one of the important strategic needs of China. Among coal thermal conversion technologies, catalytic reforming of coal pyrolysis volatile has high efficiency and wide application prospect. Changing process conditions is an important way to increase pyrolysis conversion and product yield. Optimizing reactor design and developing catalysts with high activity and stability are the important development directions of this technology. This paper firstly introduced the catalytic reforming method of low rank coal and its volatiles, on the basis of which the influence of process parameters such as temperature, atmosphere, and residence time, as well as the strategies and challenges for the application of fixed-bed and fluidized-bed reactors, were reviewed. Then, the modification methods of metal catalysts, carbon-based catalysts and zeolite catalysts and the action principles of their post-treatment and in-situ control were analyzed. The catalytic cracking mechanism of pyrolytic volatiles was summarized. The paper also pointed out the bottlenecks of the catalytic reforming of coal pyrolysis volatiles in industrialized production. The key role of the catalytic conversion path of volatile low carbon hydrocarbons and macromolecular compounds in the directional regulation of secondary reactions during coal pyrolysis was identified, and the influence of acid-catalyzed protonation on the deactivation mechanism of catalysts was deeply explored. © 2024 Chemical Industry Press Co., Ltd..
