Abstract
A hydrocracking process is provided comprising contacting a hydrocarbon stream under hydrocracking conditions and in the presence of hydrogen with a catalyst composition which comprises a synthetic porous crystalline zeolite having a particular X-ray diffraction pattern. An embodiment of the invention provides a process for reducing the pour point of a waxy component-containing hydrocarbon oil by hydrocracking and dewaxing. Another embodiment of the invention provides a dual-stage hydrocracking process to produce premium gasoline and distillate boiling range products.
Claims25
A hydrocracking process comprising the step of contacting a hydrocarbon stream under hydrocracking conditions and in the presence of hydrogen with a hydrocracking catalyst composition comprising a synthetic porous crystalline zeolite having an X-ray diffraction pattern including lines set forth in Table I of the specification, is obtained
A dual stage hydrocracking conversion process which comprises:
- (a) contacting a hydrocarbon stream boiling above a temperature of about 300.degree. F. in a first stage under hydrocracking conditions and in the presence of hydrogen with a first hydrocracking catalyst composition comprising (i) a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification and (ii) at least one hydrogentaion component to provide a first hydrocracked effluent;
- and
- (b) contacting said first hydrocracked effluent in a second stage under hydrocracking conditions and in the presence of hydrogen with a second hydrocracking catalyst composition comprising (i) zeolite Beta and (ii) at least one hydrogenation component to provide a second hydrocracked effluent.
A process for reducing the pour point of a waxy component-containing hydrocarbon oil feed which comprises contacting said feed with a catalyst composition under conditions suitable to effect hydrocracking and dewaxing of said feed to provide a hydrocracked/dewaxed product of reduced pour point, said catalyst composition comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification.
