催化甲烷-二氧化碳干重整技术现状及催化剂研究进展
Current status of dry reforming of methane and carbon dioxide technology and research progress of catalysts
摘要
Abstract
In order to cope with global climate change and promote sustainable development,the dry reforming of methane(CH4)and carbon dioxide(CO2)(DRM)has become an important development direction of chemical industry because of its unique environmental protection and economic benefits.This technology can not only effectively reduce greenhouse gas emissions,but also transform CH4 and CO2 into high-value chemical raw materials,providing high-quality synthesis gas for industrial applications such as Fischer-Tropsch synthesis,which has important practical significance in environmental protection and resource utilization.The related literatures about DRM at home and abroad were counted,and the reaction mechanism and thermodynamics of DRM were discussed.The types and research progress on DRM catalysts were summarized from the aspects of adding metal additives and controlling the interaction between carriers,and the existing problems of DRM technology were analyzed and corresponding improvement measures were put forward in view of the existing problems.It is found that the number of literatures related to DRM has increased year by year since 2000,with a slight decline in recent two years,and the research content and direction are more in-depth and diversified.The existing catalysts have some problems such as high cost,easy carbon deposition and sintering,which can be optimized by adding appropriate additives,nitrogen doping,activated carbon modification and so on.However,DRM reaction needs high temperature to be carried out effectively,which increases the energy consumption and needs strict equipment requirements,and the gas flow rate,pressure and n(CH4)/n(CO2)in the reaction process have a significant impact on the reaction efficiency.In future research,more attention should be paid to development and optimization of green,sustainable and high-performance DRM catalysts and reactors.关键词
