Catalytic conversion with boron trifluoride treated zeolite
Patent
·
OSTI ID:6184419
A process is described for dewaxing feedstock comprising hydrocarbon compounds to dewaxed conversion product which comprises contacting the feedstock with a catalyst composition comprising a crystalline zeolite having been modified by the method comprising contacting the zeolite having a silica-to-alumina mole ratio of from about 30 to about 300 and a Constraint Index of from about 1 to about 12 with gaseous boron trifluoride in the absence of alumina-containing binder. Under a combination of conditions of temperature, contact time and pressure, the combination of conditions are effective to reduce the activity of the zeolite for cracking normal hexane as measured by the alpha test conducted at 538/sup 0/C.
