Abstract: Described herein are processes for hydroisomerising an unconventional feedstock using a hydroisomerisation catalyst comprising zeolite SSZ-91, zeolite SSZ-32, or zeolite SSZ-32x to provide a diesel fuel.

Abstract: An improved hydroisomerization catalyst and process for making a base oil product using a catalyst comprising SSZ-91 molecular sieve and ZSM-12 molecular sieve. The catalyst and process generally involves the use of a catalyst comprising an SSZ-91 molecular sieve combined with a ZSM-12 molecular sieve to produce dewaxed base oil products by contacting the catalyst with a hydrocarbon feedstock. The catalyst and process provide improved base oil cold properties, such as pour point and cloud point, along with other beneficial base oil properties.

Abstract: A method for making a hydroisomerization catalyst having improved thermal stability and metal dispersion characteristics, the catalyst prepared therefrom, and a process for making a base oil product using the catalyst are disclosed. The catalyst is prepared from a composition comprising an SSZ-91 molecular sieve and a rare earth modified alumina, with the composition being modified to contain a Group 8-10 metal, typically through impregnation of a Group 8-10 metal composition. The catalyst may be used to produce dewaxed base oil products by contacting the catalyst under hydroisomerization conditions with a hydrocarbon feedstock.

Abstract: An improved process and catalyst system for making a base oil product and for reducing base oil aromatics content, while also providing good product yields. The process and catalyst system generally involves the use of a bimetallic SSZ-91 catalyst by contacting the catalyst with a hydrocarbon feedstock to provide dewaxed base oil products.

Abstract: A method for synthesizing a molecular sieve comprising providing a reaction mixture sufficient to synthesize the molecular sieve, maintaining the reaction mixture under crystallization conditions, monitoring at least one viscometric parameter of the reaction mixture, and determining an endpoint based on the monitoring of the at least one viscometric parameter.

Abstract: The invention is directed to a method for making small crystal zeolites, such as small crystal SSZ-32, in the absence of an amine component.

Abstract: An improved process for the catalytic partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is disclosed. The process also utilizes a novel catalyst configuration containing at least two serially aligned layers containing a noble metal or transition metal catalyst supported on a support. Alternatively the process employs only the first layer of a catalytically active metal dispersed on an inert carrier support to partially oxidize hydrocarbons.
