Abstract

Abstract: Kinetic analysis for understanding the reaction mechanism and hydrocarbon transformations rules has both theoretical and practical significance. The typical development and main research methods at different scales for alkylation kinetics are reviewed in this paper. Recommendations for improving the catalyst are made. The molecular-based kinetic modeling could provide detailed and explicit descriptions of the intrinsic kinetic properties, which reflect the relationship between the kinetic parameters and the feedstock, reaction conditions and catalyst. Mechanistic kinetic modeling could show important theoretical support for the optimization of reactor configuration, technological process and catalysts research.

Key words: alkylation, solid acid, kinetics, catalyst deactivation, mechanistic kinetic modeling
