Combined hydrocracking and catalytic dewaxing process
Abstract
Abstract A PROCESS FOR PRODUCING JET FUEL FROM A HYDROCARBON FEEDSTOCK BOILING SUBSTANTIALLY BELOW ABOUT 1000*F. COMPRISING SEPARATING THE FEEDSTOCK INTO A FIRST 500*F.600*F. FRACTION AND A 600*F.-1000*F. FRACTION CONTACTING THE 600*-1000*F. FRACTION WITH HYDROGEN AND A HYDROCRACKING CATALYST IN A HYDROCRACKING ZONE AT HYDROCRACKING CONDITIONS; SEPARATING THE HYDROCRACKATE INTO A 100*F.-300*F. FRACTION, A 300*F.-500*F. FRACTION, AND A SECOND 500*F.-600*F. FRACTION; CONTACTING THE 500*F.-600*F. FRACTIONS WITH HYDROGEN AND A CATALYST COMPRISING MORDENITE IN HYDROGEN FORM AND AT LEAST ONE HYDROGENATING COMPONENT IN A CATALYTIC DEWAXING ZONE AT CATALYTIC DEWAXING CONDITIONS; AND SEPARATING THE CATALYTIC DEWAXATE INTO A SECOND 100*F.-300*F. FRACTION AND A 300*F.-600*F. JET FUEL. THE HYDROCARBON FEEDSTOCK IS PREFERABLY A HYDROFINED HYDROCARBON FEEDSTOCK.
