Molten salt preparation of mixed transition metals on zirconia. Application to hydrotreating reactions

Abstract

This paper reports an experimental study of the capability of molten salt reactions to obtain in one step promoted hydrotreating catalysts. Preparation and characterization of catalysts are described, catalytic properties are determined by conversion of thiophene, tetraline and n-pentylamine. It is deduced that one step synthesis in molten nitrates for the preparation of zirconia supported catalysts provides high surface area with an enhanced thermal stability for these new catalysts
