Document Type and Number:
WIPO Patent Application WO/2000/056447
Kind Code:
A1
Abstract:
A method for a solid acid catalyst which contains sulfuric acid, exhibits a satisfactorily high activity even when formed into moldings, and also has a satisfactory mechanical strength and an easiness to handle sufficient to practical operation. The carrier of the catalyst is composed of a part comprising zirconia and/or zirconia hydrate and a part comprising alumina and/or alumina hydrate, and the method (a) comprises a step preparing a carrier which has a pore diameter distribution from 0.05 to 10 $g(m)m showing a peak in the range of 0.05 to 1 $g(m)m and a step supporting sulfuric acid on the carrier, or (b) comprises a step preparing a carrier which has a pore volume of 0.05 to 0.5 ml/g in the range of pore diameter of 0.05 to 1 $g(m)m and a pore volume less than 0.05 ml/g in the range of pore diameter more than 1 $g(m)m and up to 10 $g(m)m and a step supporting sulfuric acid on the carrier.
