Process for combinatorial synthesis and testing of heterogeneous catalysts

摘要

Heterogeneous catalyst arrays comprise a body having at least n, preferably parallel, through channels containing n different heterogeneous catalysts and/or their precursors, whereby n is 2(10), preferably 100, Heterogeneous catalyst arrays (I) comprising a body having, preferably parallel, through channels and in at least n channels having n different heterogeneous catalysts and/or their precursors, whereby n is 2(10), preferably 100, are prepared by (A1) preparation of solutions, emulsions and/or dispersions of elements and/or compounds to be present in the catalyst and/or precursor, and optionally dispersions of inorganic support materials (A2) optionally introducing adhesion promoters, binding agents, viscosity regulators, pH buffers and/or solid inorganic supports into the solution, emulsion and/or dispersion from (A1) (A3) simultaneously or sequentially coating the channels of the body with the solution, emulsion and/or dispersion whereby a predetermined quantity of solution, emulsion and/or dispersion is introduced to prepare a predetermined composition, (A4) treatment and conversion of the freshly impregnated damp channels with one or more reactive gases and (A5) optionally heating the coated body, optionally in the presence of inert- or reactive gases to 20-1500 degrees C to dry and optionally sinter or calcine the catalysts and/or catalyst precursors. An Independent claim is included for a process to determine the activity selectivity and stability of catalysts in the array (I) by optionally activating the catalysts on the body, heating the catalysts to a desired temperature, guiding a fluid reactant or mixture through the channels, removal of the reacted fluid from individual or multiple channels, analysis of the fluid and optionally evaluation of the analytical results from a number of analyses.
