Conversion of hydrocarbons for the production of unsaturates and gasoline with the use of inert solids

Claim 1

THE PROCESS OF CONVERTING HEAVY PETROLEUM OIL TO LOWER BOILING HYDROCARBONS WHICH COMPRISES FEEDING SAID OIL INTO CONTACT WITH A RAPIDLY FLOWING REACTION STREAM OF FINELY DIVIDED SOLID PRODUCTS WHICH ARE SUBSTANTIALLY INERT AND ARE PREHEATED TO A TEMPERATRE SUFFICIENTLY HIGH TO RAISE THE TEMPERATURE OF THE OIL TO AT LEAST 1200* F., MAINTAINING A CONTACT TIME OF 0.1 TO 10 SECONDS TO PRODUCE HIGH TEMPERATURE REACTION PRODUCTS INCLUDING SUBSTANTIAL PROPORTIONS OF LOW MOLECULAR WEIGHT OLEFINIC HYDROCARBONS, INTRODUCING A SECOND STREAM OF OIL FEED INTO THE REACTION STREAM AFTER THE AFORESAID CONTACTING IN SUFFICIENT QUANTITY TO SUBSTANTIALLY REDUCE THE REACTION TEMPERATURE TO A RANGE BETWEEN ABOUT 950* AND 1200* F. TO QUENCH CONVERSION AND DEGRADATION OF SAID LOW MOLECULAR WEIGHT OLEFINIC HYDROCARBONS AND ALSO TO INITIATE CONVERSION OF SAID SECOND STREAM TO PRODUCTS INCLUDING SUBSTANTIAL PROPORTIONS OF HYDROCARBONS BOILING IN THE GASOLINE BOILING RANGE, INTRODUCING ADDITIONAL HOT SOLID PARTICLES INTO SAID REACTION STREAM TO MAINTAIN A CONVERSION TEMPERATURE WITHIN THE RANGE LAST SPECIFIED, SEPARATING THE REACTION PRODUCTS FROM SAID SOLIDS AND CONTINUOUSLY REHEATING AND RECYCLING AT LEAST A PORTION OF SAID SOLID PARTICLES TO MAINTAIN CONTINUOUS OPERATION IN BOTH STAGES.
