The Fischer-Tropsch synthesis over the bimetallic Ru-M/Al_2O_3-catalysts

摘要

The structure and catalytic properties of bimetallic Ru-M /Al_2O_3 Fischer-Tropsch catalysts were studied(M = Fe,Co,V,Cr,Mn,Ce,Cu).The wide varieties of products(the hydrocarbons and the alcohols)are formed by the CO hydrogenation over bimetallic Ru-M/Al_2O_3 catalysts of cluster type.The yield and the composition of products are determined by the nature of second metals of bimetallic Ru-M/Al_2O_3 catalysts.The adsorption of CO and H_2 was studied using the techniques of microcalorimetry,thermal desorption,IR-spectroscopy and quantum-chemical accounts.
