Process and materials for trim dewaxing of distillates
Described herein are novel and inventive dewaxing processes that employ dewaxing catalysts which are co-extrusions of two different zeolites, particularly two different 10MR zeolites or a co-extrusion of a 10MR zeolite and a 12MR zeolite in combination with a hydrogenation component. The hydrogenation component can be a mixture of non-noble metal components or a mixture of noble metal components. This novel and inventive process demonstrated a significant activity boost (as measured by increased cloud point reduction) and/or selectivity boost (as measured by reduced diesel loss) compared to either single zeolite component.
Hydrocracking catalyst and process using molecular sieve SSZ-91
Described herein is a hydrocracking catalyst and process that may be used to make middle distillates and unconverted oil having beneficial yield and product characteristics. The process generally comprises contacting a hydrocarbon feed with the hydrocracking catalyst under hydrocracking conditions to produce a product comprising middle distillates and unconverted oil products. The hydrocracking catalyst comprises an SSZ-91 molecular sieve and a modifying metal selected from one or more Group 6 metals, and, optionally, one or more Group 8 to 10 metals, or a modifying metal selected from Group 8 to 10 metals and combinations thereof, and, optionally, one or more Group 6 metals. The hydrocracking catalyst may comprise a matrix material and/or an additional zeolite.
