Production of gasoline by thermal cracking, catalytic cracking and reforming

Claim 1

A PROCESS FOR THE PRODUCTION OF GASOLINE FROM HEAVY HYDROCARBON OIL WHICH COMPRISES SUBJECTING A HEAVY HYDROCARBON OIL TO THERMAL CRACKING UNDER CONDITIONS TO PRODUCE AN OLEFINIC THERMALLY CRACKED GASOLINE, SEPARATING FROM THE THERMALLY CRACKED GASOLINE THUS PRODUCED THE LOWER BOILING PART UP THROUGH ABOUT C6 HYDROCARBONS, CATALYTICALLY CRACKING THE REMAINDER OF THE THERMALLY CRACKED GASOLINE BY ITSELF AT A TEMPERATURE ABOVE 900* F. AND AT A SEVERITY TO CRACK MOST OF THE OLEFINS TO LOWER BOILING PRODUCTS, SEPARATING SAID LOWER BOILING PRODUCTS AND SUBJECTING THE REMAINDER TO A CATALYTIC REFORMING TREATMENT WITH A DEHYDROGENATION CATALYST.
