REGENERATION OF ZNCL.SUB.2

摘要

A method of hydrocracking using a zinc catalyst in the hydrogenation step comprising providing a hydrocarbonaceous feed of coal or tar to a hydrogenation means, removing spent zinc and catalyst from said hydrogenation means to a regeneration means, heating said spent zinc catalyst in said regeneration means, providing hydrogen chloride to said regeneration means, said spent zinc catalyst comprising ZnS, whereby ZnCl2 gas is formed, contacting at least a portion of said ZnCl2 with steam to form ZnO, conveying said ZnO and ZnCl2 to said hydrogenation means.
