Process of petrolatum cracking in liquid and vapor phase

Claim 1

A PROCESS FOR CRACKING PERTOLATUM FOR PRODUCING PRINCIPALLY HIGH YIELDS OF C9 TO C19 ALPHA OLEFINS, WHICH COMPRISES HEATING PETROLATUM DISTILLATE FREED FROM TARRY RESIDUE BOILING ABOVE 650* F. IN LIQUID PHASE AT LIQUIDPHASE CRACKING TEMPERATURES IN THE RANGE OF 750* TO 950* F. FOR A PERIOD UP TO ABOUT 8 SECONDS TO EFFECT 12 TO 20 WT. PERCENT OF TOTAL CRACKING WHILE THE PETROLATUM IS MAINTAINED IN LIQUID PHASE, DISPERSING THE RESULTING LIQUIDPHASE CRACKED PETROLATUM PRODUCTS INTO A STREAM OF STEAM SUPERHEATED TO ABOVE 1000* F. AT THE INLET TO A VAPORPHASE CRACKING ZONE TO VAPORIZE THE LIQUID PHASE CRACKED PETROLATUM PRODUCTS AS THEY ARE ADMITTED TO SAID VAPOR PHASE CRACKING ZONE, THEN PASSING THE STEAM CONTAINING SAID VAPORIZED CRACKED PRODUCTS THROUGH SAID VAPOR PHASE CRACKING ZONE WHEREIN SAID PRODUCTS ARE HEATED TO A VAPOR PHASE CRACKING TEMPERATURE IN THE RANGE OF 1000* TO 1250* F. FOR A PERIOD TO OBTAIN THE REMAINDER OF 25 TO 45 WT. PERCENT CONVERSION OF THE PETROLATUM, THEN COOLING THE CRACKED PRODUCTS AND FRACTIONATING FROM THE CRACKED PRODUCTS C9 THROUGH C19 OLEFINS.
