Catalyst for hydrocarbon conversions

Claim 1

A CATALYTIC PROCESS FOR SELECTIVELY CONVERTING DURING A SINGLE CONTACT WITH CATALYST, AT LEAST 20% OF HYDROCARBON FEED OF LOW NITROGEN CONTENT TO PRODUCTS BOILING BELOW THE INITIAL BOILING POINT OF SAID FEED WITH A MINIMUM LOSS OF FEED TO UNDERSIRABLE SIDE REACTIONS, WHICH COMPRISES PASSING SAID FEED, ALONG WITH AT LEAST 1500 S.C.F. OF HYDROGEN PER BARREL OF SAID FEED AND WITH THE COMSUMPTION OF AT LEAST 500 S.C.F. OF HYDROGEN PER BARREL OF SAID FEED CONVERTED TO LOWER BOILING PRODUCTS, AT MORE THAN 350 P.S.I.G. HYDROGEN PARTIAL PRESSURE AND BELOW 750*F. AT MORE THAN 0.2 V./V./HOUR LIQUID HOURLY SPACE VELOCITY, OVER A SULFIDED NICKEL FLUORIDE SILICA-ALUMINA CATALYST PREPARED BY CHEMISORBING 5 TO 40%, ON A DRY WEIGHT BASIS, OF NICKEL FLUORIDE ON AN ACITVE ALUMINA-CONTAINING CRACKING SUPPORT, REMOVING RESIDUAL WATER-EXTRACTABLE FLUORIDE, AND LEAVING CHEMISORBED METAL FLUORIDE ON SAID SUPPORT AND SULFIDING THE RESULTING DRIED FLUORIDE-CONTAINING CATALYST.
