  • Publication number: 20230211328
    Abstract: 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.
