โœฆ Synopsis


On the basis of X-ray analysis data the effect of dispersity and habit of the nickel crystallite, as well as the effect of lead addition on the catalytic properties of nickel-containing zeolites of Y-type, is studied. As model reactions, the disproportionation of toluene and the methanation of carbon monoxide are used. The observed changes in the catalytic activity of differently dispersed nickel are related to the changes in the ratio between the crystallographic faces, determining the catalytic functions of the metal. A specific influence of the zeolite carrier on the dispersity is established.

The dispersion states of reduced nickel on zeolites and their activities were studied on a series of nickel-zeolites A, X, Y and nickel-mordenites. The dispersion of nickel was affected by the types of zeolite support, and increased in the order; NiNa-Y < NiNa-X < NiNa-M NiNa-A. The reduced nickel w

A series of nickel-zeolite catalysts with alkaline earth, lanthanum and hydrogen ions as parent-cations in zeolite Y were prepared. The degrees of nickel ion reduction and the dispersion states of reduced nickel were affected by the extent of nickel-exchange and by the types of parent-cations in zeo
