Abstract
A zeolite having the ferrierite framework structure is produced using one or more of n-propylamine, n-butylamine, isobutylamine, and n-amylamine as a structure directing agent.
Claims11
A method of synthesizing a zeolite of FER framework type, the method comprising:
- (1) forming a reaction mixture comprising:
- (a) a source of silicon;
- (b) a source of aluminum;
- (c) a structure directing agent (Q) comprising n-propylamine, n-butylamine, isobutylamine, n-amylamine, or a combination thereof;
- (d) a source of an alkali metal (M);
- (e) a source of hydroxide ions;
- (f) water;
- and
- (g) seeds;
- and
- (2) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the zeolite;
- wherein the reaction mixture comprises an alumina-coated silica as a combined source of silicon and aluminum.
