Abstract

Acids and bases generally occur in pairs as concepts, and numerous catalytic reactions can be considered as interactions between them. Many reactions are a combination of acid- and base-catalyzed processes, so it is particularly important to understand the mechanisms from acid-base synergy or acid-base interactions. Compared to the wide research on acid catalysts, there is a relative lack of research on solid bases. In addition to the application of basic materials to non-petroleum processes, recent studies have also applied them to the catalytic cracking reaction of heavy oils, providing new ideas for the heavy oils refining. Thus, this paper summarizes the progress of the main types of all-inorganic solid base catalysts, including the types of catalysts used in non-petroleum processes and petroleum processes, preparation, the properties of basic sites and their catalytic role in the reactions, and provides an outlook on the future research of all-inorganic solid base materials.
