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 µm in a pore diameter distribution of 0.05 to 10 µm; 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 µm and not more than 1 µm occupy a pore volume of 0.05 to 0.5 ml/g and pores having a pore diameter of above 1 µm and not more than 10 µm occupy a pore volume of below 0.05 ml/g; and having a sulfureous component supported on the support.

On décrit un procédé pour un catalyseur acide solide qui contient de l'acide sulfurique, présente une activité élevée satisfaisante même lorsqu'il est formé en objets moulés, ainsi qu'une résistance mécanique satisfaisante et une maniabilité suffisante permettant une exploitation pratique. Le support du catalyseur est composé d'une partie comprenant de la zircone et/ou de l'hydrate de zircone, et d'une partie comprenant de l'alumine et/ou de l'hydrate d'alumine. Le procédé comprend: a) une étape consistant à préparer un support dont la distribution du diamètre des pores, comprise entre 0,05 et 10 mu m, indique un pic de l'ordre de 0,05 à 1 mu m, et une étape consistant à placer de l'acide sulfurique sur le support; ou b) une étape consistant à préparer un support présentant un volume des pores compris entre 0,05 et 0,5 ml/g pour un diamètre des pores de l'ordre de 0,05 à 1 mu m et un volume des pores inférieur à 0,05 ml/g pour un diamètre des pores de l'ordre de 1 à 10 mu m, et une étape consistant à placer de l'acide sulfurique sur le support.
