A method for producing a solid acid catalyst is provided which produces a shaped material of a solid acid catalyst containing a sulfureous component but have a high activity and having a practically sufficient handleability and mechanical strength. The method comprises (a) fabricating a support comprising a portion of zirconia and/or hydrated zirconia and a portion of alumina and/or hydrated alumina and having a peak in diameter in the range of 0.05 to 1 mu m in a pore diameter distribution of 0.05 to 10 mu m; and having a sulfureous component supported on the support or (b) fabricating a support comprising a portion of zirconia and/or hydrated zirconia and a portion of alumina and/or hydrated alumina and including pores having a pore diameter of not less than 0.05 mu m and not more than 1 mu m occupy a pore volume of 0.05 to 0.5 ml/g and pores having a pore diameter of above 1 mu m and not more than 10 mu m occupy a pore volume of below 0.05 ml/g; and having a sulfureous component supported on the support. |
