一、前言固体磷酸催化剂,是一种比较通用的工业催化剂,广泛用于烯烃和芳烃的烃化、烯烃的低聚、水合异构、烷基苯的脱烷基反应、歧化及二甲基二氧六环分解制异戊二烯等工艺。固体磺酸催化剂,通常是由强磷酸与硅藻土共混,经成型、干燥、活化制得。催化剂在活化过程中,生成具有不同组成和结晶 I. Introduction Solid phosphoric acid catalyst is a kind of common industrial catalyst widely used in the alkylation of olefins and aromatics, the oligomerization of olefins, the isomerization of hydration, the dealkylation of alkyl benzenes, the disproportionation and the formation of dimethyldi Oxycycline decomposition of isoprene and other processes. Solid sulfonic acid catalyst, usually by strong phosphoric acid and diatomite blend, by molding, drying, activation obtained. Catalysts generate different compositions and crystallites during activation
