Abstract

A process for preparing arrays of two or more heterogeneous catalysts, heterogeneous catalyst precursors, or combinations thereof in a body having preferably parallel through-channels. In this process, a solution, emulsion or dispersion of elements present in the catalyst, catalyst precursor, or combination thereof, is first prepared, and is used to simultaneously or successively coat the channels of the body to produce freshly impregnated moist channels. These channels are then treated and reacted with one or more reactive gases, and the coated body is optionally heated in the presence or absence of inert or reactive gases.
