Because the whole world is under threat from climate change, 195 countries decided to reduce greenhouse gas (GHG) emissions by adopting the “Paris Agreement”. The mitigation and utilization of GHG have become the most significant challenges in the area of green energy research. One feasible solution is the reforming of methane with carbon dioxide (called dry reforming of methane, DRM) that converts the two main GHGs (CO2 and CH4) into synthesis gas (H2 and CO), which is a resource for the manufacture of useful value-added products. The main issue that needs to be addressed for DRM is the deactivation of catalysts by sintering and carbon formation. Design of a viable catalyst that exhibits high catalytic activity and stability, as well as resistance against deactivation, could be accomplished by making appropriate choices of active metal, support, promoter, structure and methods for preparation and activation. Numerous studies and reviews have dealt with various aspects of DRM. This review focuses on the physicochemical properties of the pertinent catalysts and their role in the catalytic performance needed for DRM. Specifically, the interaction between components, dispersion, particle size, basicity, oxygen storage capacity, reducibility, porosity and surface area are discussed. This study provides the understanding of catalytic properties and their correlation with catalytic performance needed for the rational design of catalysts and suitable for DRM.

甲烷干法重整研究的催化性能

由于全世界都受到气候变化的威胁,因此有195个国家决定通过《巴黎协定》以减少温室气体(GHG)的排放。减少和利用温室气体已成为绿色能源研究领域中最重大的挑战。一种可行的解决方案是用二氧化碳对甲烷进行重整(称为甲烷的干重整,DRM),将两种主要的温室气体(CO 2和CH 4)转化为合成气(H 2)。和CO),这是制造有用的增值产品的资源。DRM需要解决的主要问题是通过烧结和碳形成使催化剂失活。一个可行的催化剂,该催化剂表现出高的催化活性和稳定性,以及对失活性,可通过使活性金属,载体,启动子,结构的适当的选择和方法制备和活化来完成的设计。许多研究和评论都涉及DRM的各个方面。这篇综述着重于相关催化剂的物理化学性质及其在DRM所需的催化性能中的作用。具体地说,讨论了组分,分散体,粒度,碱度,储氧量,还原性,孔隙率和表面积之间的相互作用。
