Conversion of hydrocarbons

Claim 1

A METHOD FOR CONVERTING HIGHER BOILING HYDROCARBONS TO LOWER BOILING HYDROCARBONS WHICH COMPRISES CONTACTING HIGHER BOILING HYDROCARBONS WITH FINELY DIVIDED SOLID CATALYST PARTICLES IN A CONTACTING ZONE AT A TEMPERATURE OF ABOUT 850* -1000* F. MAINTAINING SAID HYDROCARONS IN CONTACT WITH SAID CATALYST IN SAID CONTACTING ZONE AT SAID TEMPERATURE TO PRODUCE HYDROCARBONS BOILING BELOW 430* F. AND COKE, SEPARATING THE TOTAL VAPOROUS CONVERTING HYDROCARBONS FROM SPENT CATALYST, MIXING SHOT PARTICLES HEATED AT A TEMPERATURE BETWEEN ABOUT 1050* AND 1200* F. WITH SAID SEPARATED HOT TOTAL VAPOROUS CONVERTED HYDROCARBONS SUBSTANTIALLY FREE OF SPENT CATALYST PASSING THE RESULTANT MIXTURE THROUGH A SOAKING ZONE WHEREIN SAID CONVERTED HYDROCARBONS ARE MAINTAINED AT A HIGHER TEMPERATURE THAN IN SAID CONTACTING ZONE AND BETWEEN ABOUT 950* AND 1150* F. UNTIL ADDITIONAL HYDROCARBONS ARE CONVERTED TO COMPONENTS BOILING BELOW 430* F., SEPARATING COOLED SHOT FROM THE FURTHER CONVERTED VAPOROUS HYDROCARBONS LEAVING SAID SOAKING ZONE AND SEBSEQUENTLY RECOVERING MOTOR FUEL FROM THE FURTHER CONVERTED HYDROCARBONS, WITHDRAWING SPEND CATALYST PARTICLES FROM SAID CONTACTING ZONE AND PASSING THEM TO A REGENERATING ZONE WHEREIN THEY ARE REGENERATED WITH AN OXIDIZING GAS AND REHEATED BEFORE BEING RETURNED TO SAID CONTACTING ZONE AND UTILIZING SOME OF THE HEAT OF REGENERATION TO HEAT SAID SEPARATED SHOT BEFORE RECYLCING IT TO SAID SOAKING ZONE.

Claim 2

A METHOD FOR CONVERTING HIGHER BOILING HYDROCARBONS TO LOWER BOILING HYDROCARBONS WHICH COMPRISES CONTACTING HIGHER BOILING HYDROCARBONS WITH FINELY DIVIDED SOLID CATALYST PARTICLES IN A CONTACTING ZONE AT A TEMPERATURE OF ABOUT 850* -1000* F. MAINTAINING SAID HYDROCARONS IN CONTACT WITH SAID CATALYST IN SAID CONTACTING ZONE AT SAID TEMPERATURE TO PRODUCE HYDROCARBONS BOILING BELOW 430* F. AND COKE, SEPARATING THE TOTAL VAPOROUS CONVERTING HYDROCARBONS FROM SPENT CATALYST, MIXING SHOT PARTICLES HEATED AT A TEMPERATURE BETWEEN ABOUT 1050* AND 1200* F. WITH SAID SEPARATED HOT TOTAL VAPOROUS CONVERTED HYDROCARBONS SUBSTANTIALLY FREE OF SPENT CATALYST PASSING THE RESULTANT MIXTURE THROUGH A SOAKING ZONE WHEREIN SAID CONVERTED HYDROCARBONS ARE MAINTAINED AT A HIGHER TEMPERATURE THAN IN SAID CONTACTING ZONE AND BETWEEN ABOUT 950* AND 1150* F. UNTIL ADDITIONAL HYDROCARBONS ARE CONVERTED TO COMPONENTS BOILING BELOW 430* F., SEPARATING COOLED SHOT FROM THE FURTHER CONVERTED VAPOROUS HYDROCARBONS LEAVING SAID SOAKING ZONE AND SEBSEQUENTLY RECOVERING MOTOR FUEL FROM THE FURTHER CONVERTED HYDROCARBONS, WITHDRAWING SPEND CATALYST PARTICLES FROM SAID CONTACTING ZONE AND PASSING THEM TO A REGENERATING ZONE WHEREIN THEY ARE REGENERATED WITH AN OXIDIZING GAS AND REHEATED BEFORE BEING RETURNED TO SAID CONTACTING ZONE AND UTILIZING SOME OF THE HEAT OF REGENERATION TO HEAT SAID SEPARATED SHOT BEFORE RECYLCING IT TO SAID SOAKING ZONE.
