    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 specific type of zeolite based catalyst which has been found to provide high conversion with minimal iso-paraffin products. In one embodiment, the zeolite is of the framework PWO. The reaction conducted in the presence of the zeolite based catalyst produces an n-paraffin rich product that needs no separation step before being fed to a steam cracker to produce lower olefins.

    Abstract: An organotemplate-free synthetic process for synthesizing an aluminosilicate molecular sieve SSZ-122 is provided. The process includes (1) preparing a reaction mixture comprising: (a) a silicon atom source; (b) an aluminum atom source; (c) a source of an alkali metal [M]; (d) a source of hydroxide ions; (e) water; and (f) seed crystals; and (2) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the aluminosilicate molecular sieve.

    Abstract: A method for synthesizing an aluminosilicate molecular sieve of SWY framework topology via interzeolitic conversion is described. The method includes (1) a step of preparing a reaction mixture containing an aluminosilicate zeolite of FAU framework topology, a structure directing agent comprising a 1-methyl-1-[7-(trimethylammonio)heptyl]piperidinium cation, a source of an alkali metal cation, a source of hydroxide ions, and water; and (2) a step of heating the reaction mixture to obtain an aluminosilicate molecular sieve of SWY framework topology.
