Copper-containing catalyst with fixed active component on alumosilicate substrate

It was found that the low thermal stability of the industrial copper-containing catalyst from BASF is associated with the chemical looseness of the active component on the surface of the silica-earth support, and the deterioration of its strength properties occurs due to the phase transition of the SiO2 (?-quartz) support to ? - cristobalite. A thermostable copper-containing catalyst MAK-K with an active component tightly bound to an alumina-silica support has been proposed and investigated. Experimental tests of catalysts for thermal stability showed that at 350 ° C the relative activity of catalyst H3-11 decreases by 41%, while the relative activity of catalyst MAK-K changed by only 15%.
