NU-1 TYPE BINDERLESS ZEOLITE MOLDING AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a binderless zeolite molding substantially consisting of NU-1 type zeolite alone. SOLUTION: The zeolite precursor expressed by the formula Si1(TMA)xM1yM2z (where, TMA denotes tetramethyl ammonium; M1 denotes an alkaline metal; M2 denotes the metal element to be incorporated into a metallosilicate crystal skeleton; (x) denotes a range of 0.01 to 1; (y) 0.0001 to 1; and (z) 0 to 0.3) is brought into contact with saturated steam of 80 to 260 deg.C.
