Publication number: 20180264442Abstract: A method is described for preparing a catalyst comprising the steps of (i) preparing a calcined shaped calcium aluminate catalyst support, (ii) treating the calcined shaped calcium aluminate support with water, and then drying the support, (iii) impregnating the dried support with a solution containing one or more metal compounds and drying the impregnated support, (iv) calcining the dried impregnated support, to form metal oxide on the surface of the support and (v) optionally repeating steps (ii), (iii) and (iv) on the metal oxide coated support. The method provides an eggshell catalyst in which the metal oxide is concentrated in an outer layer on the support.Type: ApplicationFiled: April 16, 2018Publication date: September 20, 2018Inventors: Mikael Per Uno CARLSSON, Jonathan Geoffrey OLIVER, Mark Robert FEAVIOUR, David James BIRDSALL, Samuel Arthur FRENCH
