Superacid catalyst based on sulfated zirconium oxide, its use for the hydroisomerization of n-paraffins and process for its preparation

摘要

A superacid catalyst is described based on sulfated zirconium oxide, which can additionally contain a noble metal, characterized by a porosity ranging from 0.1 to 0.3 cm²/g consisting of at least 70% of pores with a diameter ranging from 1 to 4 nm.;The preparation of the above catalyst which comprises the use of a tetra-alkylammonium hydroxide, its activity in acid catalyzed reactions and its use in the dehydroisomerization of n-paraffins, are also described.
