Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a selected catalyst, e.g., an LTA-type zeolite, with a requisite topology and acid site density. The zeolite has a framework type with voids greater than 0.50 nm in diameter, which are accessible through apertures characterized by a longest diameter of less than 0.50 nm and a shortest diameter of more than 0.30 nm. The reaction conducted in the presence of such a selected zeolite produces an n-paraffin rich product.

Abstract: A method of increasing hydrophobicity of a molecular sieve is provided. The method includes: (a) providing a metallosilicate molecular sieve having a framework consisting of oxides of silicon (Si) and a metal (M), wherein M is boron or zinc; (b) contacting the metallosilicate molecular sieve with a liquid aqueous system, thereby obtaining a demetallated molecular sieve having silanol nests and empty framework sites; and (c) thermally treating the demetallated molecular sieve, thereby obtaining a thermally-treated molecular sieve, wherein the thermally-treated molecular sieve (i) retains the three-dimensional framework structure of the metallosilicate molecular sieve and (ii) has a higher Si/M molar ratio as compared to the metallosilicate molecular sieve.
