High silica DDR-type molecular sieve, its synthesis and use |
摘要 |
A crystalline material has a DDR framework type and, in its calcined, anhydrous form, has a composition involving the molar relationship: <?in-line-formulae description="In-line Formulae" end="lead"?>(n)X2O3:YO2,<?in-line-formulae description="In-line Formulae" end="tail"?> wherein X is a trivalent element, Y is a tetravalent element and n is from 0 to less than 0.01 and wherein the crystals of said material have an average diameter less than or equal to 2 microns. The material is synthesized in the presence of an N-ethyltropanium compound as directing agent.
