【Abstract】 With the formal implementation of the national Ⅵ gasoline quality standards and the gradual promotion of ethanol gasoline, the C₄ alkylation process is receiving more and more attention from refineries, since it is essential to producing high-grade gasoline and an excellent choice to add value of C₄ by-products for refineries. This paper is to review the latest researches and applications of hydrofluoric acid alkylation, sulfuric acid alkylation, ionic liquid alkylation and solid acid alkylation, outline the process characteristics and improvements of typical C₄ alkylation technologies, and discuss the development trends of C₄ alkylation units.更多还原
