Abstract

1282138 Supported catalysts STAMICARBON NV 21 Nov 1969 [23 Nov 1968] 57083/69 Heading B1E Supported catalysts are made by preparing an aqueous solution of a soluble compound of a metal, suspending carrier particles in this solution, adding a reducing agent to the mixture to precipitate the catalyst, the reduction being effected with agitation whereby the original soluble metallic compound and its reduced form are homogeneously distributed throughout the solution, and wherein the amount of reducing agent present in, and the temperature and pH of the solution are such that during the reduction precipitation is gradual and the catalyst adheres to the exterior of the carrier. Examples describe the preparation of Cu 2 O, Pt, MoO 2 and other catalysts onto SiO 2 gel.
