PURPOSE: A manufacturing method for a catalysis is provided to manufacture the catalysis being required for a petrochemical industry and an organic synthesis into a product of an excellent quality through a simple process. CONSTITUTION: A method for manufacturing a catalysis comprises: selecting an impurity from a clay mineral of a montmorillonite group; naturally drying by spreading on a yard for 3-4 hours; preliminarily breaking through a preliminary breaker; inputting into a sulfuric acid reactive container; inputting a sulfuric acid diluted solution being obtained by diluting a sulfuric acid and a water in the ratio of 1:4 - 1:5 for a sulfuric acid reaction; washing repeatedly the sulfuric acid reacted particle; washing for 24 hours for dropping an acid degree under 5; drying until containing 4-7 % of the contained water rate; and selecting a material with 20-60 mesh by using a selecting net. Therefore, the catalysis with an excellent quality can be manufactured for being not easily broken and dissolved.
