THE PROCESS FOR REDUCING THE POUR POINT OF A TOPPED CRUDE OIL WHICH COMPRISES THERMALLY CRACKING SAID TOPPED CRUDE OIL AT A TEMPERATURE WITHIN THE RANGE OF 800 TO 1100* F. AND AT A PRESSURE WITHIN THE RANGE OF 0 TO 100 POUNDS PER SQUARE INCH GAUGE AND CONVERTING FROM 5 TO 15 PER CENT OF SAID TOPPED CRUDE OIL TO LOWER BOILING HYDROCARBONS WITHIN THE GASOLINE BOILING RANGE PASSING THE TOTAL EFFLUENT FROM SAID THERMAL CRACKING STEP INTO CONTACT WITH A SILICA-ALUMINA CATALYST AT A TEMPERATURE WITHIN THE RANGE OF 650 TO 900* F. AND AT ATMOSPHERIC PRESSURE TO EFFECT A TRANSFER OF HYDROGEN FROM THE HIGHER BOILING TO THE LOWER BOILING COMPONENTS OF SAID EFFLUENT, SEPARATING FROM THE EFFLUENT FROM THE
