SUPERSAUER KATALYSATOR FÜR DIE HYDROISOMERISIERUNG VON N-PARAFFINEN |
摘要 |
A superacid catalyst comprising: zirconium oxide on whose surface sulfate groups are present, in a quality corresponding to total coverage of the surface of the zirconium oxide by means of a monolayer of these sulfate groups, optionally containing a noble metal in a quantity ranging from 0.1 to 3% by weight, with a porosity ranging from 0.1 to 0.30 cm3/g, consisting of at least 70% of pores with a diameter ranging from 1 to 4 nm, prepared by a process which comprises:(a) hydrolyzing derivate of zirconium in a basic medium in the presence of a tetra-alkylammonium hydroxide (TAA), sulfuric acid and acetylacetone (AcAc);(b) drying the product of step (a) and calcining the dried material at a temperature ranging from 250 to 650° C.(c) optionally treating the product resulting from step (b) with an aqueous solution of a compound of a noble metal, and drying and calcining the treated product. |
