SOLID ACID CATALYST, METHOD OF PRODUCTION OF SUCH CATALYST AND ITS APPLICATION Russian patent published in 2002 - IPC

FIELD: solid catalyst easily separated from reagents for re-use in alkylation, etherification and isomerization reactions. SUBSTANCE: method includes (a) production of carrier containing fraction of zirconium dioxide and/or hydrated zirconium dioxide and fraction of aluminum oxide and/or hydrated aluminum oxide at peak of diameter between 0.05 and 1 mcm on diameter distribution curve of pores from 0.05 to 10 mcm and application of sulfur-containing component on carrier; (2) obtaining of carrier containing fraction of zirconium dioxide and/or hydrated zirconium dioxide and fraction of aluminum oxide or hydrated aluminium oxide at volume of pores at diameter no less than 0.05 mcm and no more than 1 mcm at 0.05 to 0.5 ml/g and volume of pores at diameter higher than 1 mcm and no more than 10 mcm below 0.05 ml/g followed by application of sulfur-containing component on carrier. Invention describes also solid acid catalyst and method of performing reaction catalyzed by acid and method of carbon isomerization. EFFECT: enhanced activity, handling and mechanical strength of catalyst; application for many reactions in presence of organic compounds. 16 cl, 3 tbl, 21 dwg
