MTW-TYPE BINDERLESS ZEOLITE MOLDED FORM AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a binderless zeolite molded form consisting substantially of MTW-type zeolite alone. SOLUTION: This binderless zeolite molded form is obtained by contacting a zeolite precursor of the formula(1) :Si1(SDA)xM1yM2z (SDA is a tetraalkylammonium with at least two ethyl groups bound to the nitrogen atom; M1 is an alkali metal; M2 is a metallic element integrated into the metallosilicate skeleton; x is 0.001-1; y is 0.0001-1; z is 0-0.4) with saturated steam at 80-260 deg.C.
