Patent

CA 2058081

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 tri- alkanolamine containing at least two carbon atoms per alkanolamine moiety, to a shapable dough thus obtained, 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 tri- alkanolamine and having a total solids content between 25 and 75% by weight and a trialkanolamine content between 0.5 and 40% by weight on the total solid content of the mixture, to extrudates thus obtained, to the preparation of calcined extrudates containing dealuminated aluminosilicate zeolites and to (hydro)conversion processes, in particular hydrogenation processes using such extrudates.
