Abstract
A method is disclosed making a molecular of TON framework type having unique properties. The method uses 1,3,4-trimethylimidazolium cations as a structure directing agent and a combined source of silicon and aluminum selected from alumina-coated silica and aluminosilicate zeolites. The obtained molecular sieve can be used in processes for dewaxing paraffinic hydrocarbon feedstocks.
Claims5
A pure phase molecular sieve of TON framework having a molar ratio of SiO2/Al2O3 in a range of from 30 to 100 and, in its as-synthesized form, consisting of 1,3,4-trimethylimidazolium cations and optionally an alkali metal cation in its pores.
