ABSTRACT:A new method for conducting a heterogeneous catalytic reaction in the gaseous phase is discussed. It eliminates the use of carriers and allows catalysis to be conducted via an aerosol of finely milled active catalytic materials. Problems associated with the strength and thermal stability of catalysts are thereby avoided. A high and constant catalytic activity is ensured for the aerosol catalyst by integrating the chemical reaction zone and the mechanical treatment zone. Thus, solid particles that move with the reactant flow or special devices that allow mechanical treatment of the catalyst particles may be located in the reactor. Such aerosol catalysis has been tested in processes involving partial and complete oxidation, recovery, vinylation, chlorination and dechlorination. Relative to traditional systems, i.e. placement of the active catalytic active material on the carrier, the reaction rate was increased by 4-5 orders of magnitude. The production of catalysts and the implementation of chemical reactions are thereby both simplified simultaneously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
