The study of the activity of a zeolite catalyst in alkylation of benzene by individual C/sub 2/-C/sub 4/ olefins showed that the conversion of the olefins into alkylbenzenes in the abscence of h/sub 2/ is not dependent on the preliminary treatment of the catalyst. Figures show the effect of h/sub 2/ on the activity of NiLaY undergoing HVT and in alkylation of benzene, ethylene, propylene, isobutylene, dependence of the alkylating and hydrogenating activity of the catalyst on the amount of sorbed pyridine, and dependence of the activation energy on the amount of chemisorbed NH/sub 3/. Shown was the effect of heat-vapor treatment of a polyfunctional zeolite catalyst on the alkylating and hydrogenating activity. Also studied was the effect of the acidity by the method of partial poisoning of the surface of the zeolite catalyst, and the dependence of the catalytic properties of polyfunctional catalysts on the character of the distribution of the acid sites, which was established.
