Abstract
To assess the possibility of using spent alumina catalysts from the vapor-phase dehydration of methyl phenyl carbinol as a support of fixed-bed catalysts, we determined the textural changes and mechanical strength of the catalyst over its scheduled service life of 8000 h. It was found that the catalytic properties of a palladium catalyst prepared on this support (0.2 wt % Pd) in reactions of hydrogenation and polymerization of diene hydrocarbons in liquid pyrolysis products are as good as the commercial products APKGS-20 E2 and APKGS-20 Sh. The tested catalyst is recommended as a replacement for the inert attachment in reactors for the hydrostabilization of liquid pyrolysis products.
