Abstract
This disclosure relates to new crystalline microporous solids (including silicate- and aluminosilicate-based solids), the compositions comprising 8 and 10 membered inorganic rings, particularly those having RTH topologies having a range of Si:Al ratios, methods of preparing these and known crystalline microporous solids using certain quaternized imidazolium cation structuring agents.
Claims20
A calcined crystalline microporous solid having an RTH framework topology comprising:
- (a) silicon oxide and
- (b) an oxide of aluminum, boron, gallium, hafnium, iron, tin, titanium, indium, vanadium, zirconium, or combination thereof, wherein the molar ratio of Si to the aluminum, boron, gallium, hafnium, iron, tin, titanium, indium, vanadium, zirconium, or combination thereof is in a range of from 5 to 9.
