SOLID ACID CATALYST, METHOD FOR PRODUCING THE SAME AND REACTION METHOD USING THE SAME |
摘要 |
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 .mu.m showing a peak in the range of 0.05 to 1 .mu.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 .mu.m and a pore volume less than 0.05 ml/g in the range of pore diameter more than 1 .mu.m and up to 10 .mu.m and a step supporting sulfuric acid on the carrier. |
