Abstract:
A process for hydrocracking hydrocarbon streams comprising contacting the streams in the presence of hydrogen with a hydrocracking catalyst containing sulfides of metals of Group VIB and/or Group VIII of the Periodic Table on a porous support at a temperature within the range of 100.degree. C. to about 500.degree. C., said hydrocracking catalyst is prepared by the process comprising treating a presulfurized catalyst with a substance comprising at least one oxygen-containing hydrocarbon having at least 20 carbon atoms and have an iodine value of above 60 then liquid activating the thus-treated presulfurized catalyst by heating the treated presulfurized catalyst in the presence of hydrogen and at least one hydrocarbon, said hydrocarbon having a boiling point of above about 35.degree. C. at atmospheric pressure, said activiation is carreid out at a temperature within the range of about 25.degree. C. to about 430.degree. C., hydrogen partial pressure within the range of about 50 psig to about 3000 psig and Liquid Hourly Space Velocity of from about 0.1 to about 20 hr.sup.-1 to provide a hydrocracking catalyst.
