ABSTRACT:
The present invention relates to a process for preparing a shapable dough which comprises mixing and kneading a silica source, a dealuminated aluminosilicate zeolite source, water and a trialkanolamine containing at least two carbon atoms per alkanolamine moiety, to a shapable dough thus obtained, and to the preparation of extrudates containing dealuminated aluminosilicate zeolites by extruding a shapable dough comprising a silica source, a dealuminated aluminosilicate zeolite source, water and a trialkanolamine and having a total solids content between about 25% by weight and about 75% by weight and a trialkanolamine content between about 0.5% by weight and about 40% by weight, basis on the total solid content of the mixture.
