Hydrocarbon conversion apparatus and method of operation

Claim 1

A METHOD FOR CONVERTING RELATIVELY HIGH-BOILING HYDROCARBON FEED MATERIALS IN THE PRESENCE OF FINELY DIVIDED FLUIDIZABLE SOLID MATERIAL WHICH COMPRISES PASSING AT LEAST ONE FIRST CONFINED STREAM OF SOLIDS AS A SUSPENSION SUBSTANTIALLY VERTICAL UPWARDLY FROM A REGENERATION ZONE UNDER ELEVATED TEMPERATURE CONVERSION CONDITIONS INTO A REACTION ZONE, INTRODUCING A HYDROCARBON REACTANT INTO ONE OF A SERIES OF INLET POINTS IN SAID FIRST CONFINED STREAM, DISCHARGING SAID FIRST CONFINED STREAM IN SAID REACTION ZONE ABOVE A DENSE FLUIDIZED BED OF SOLID MATERIAL THEREIN UNDER CONDITIONS TO SEPARATE SOLID MATERIAL FROM HYDROCARBON PRODUCT MATERIAL BY SETTLING, PASSING AT LEAST ONE SECOND CONFINED STREAM OF SOLIDS AS A SUSPENSION SUBSTANTIALLY VERTICALLY UPWARDLY FROM SAID REGENERATION ZONE UNDER ELEVATED TEMPERATURE CONVERSION CONDITIONS TO THE LOWER PORTION OF SAID REACTION ZONE, INTRODUCING A HYDROCARBON REACTANT INTO AT LEAST ONE OF A SERIES OF INLET POINTS IN SAID SECOND CONFINED STREAMS, DISCHARGING FINELY DIVIDED SOLIDS AND HYDROCARBON MATERIAL FROM SAID SECOND CONFINED STREAM INTO SAID REACTION ZONE UNDER CONDITIONS TO SEPARATE FINELY DIVIDED SOLIDS, FROM HYDROCARBON, PASSING FINELY DIVIDED SOLIDS FROM SAID REACTION ZONE TO A STRIPPING ZONE FOR DOWNWARD FLOW THEREIN COUNTER-CURRENT TO STRIPPING GAS INTRODUCED TO THE LOWER PORTION THEREOF, PASSING SOLIDS FROM THE LOWER PORTION OF SAID STRIPPING ZONE AS A CONFINED STREAM DOWNWARDLY TO THE LOWER PORTION OF A REGENERATION ZONE, HEATING SAID SOLIDS IN A FLUID BED CONDITION IN SAID REGENERATION ZONE TO AN ELEVATED TEMPERATURE AND PASSING THE THUS HEATED SOLIDS TO SAID FIRST AND SECOND CONFINED STREAMS OF SOLIDS BEING PASSED TO SAID REACTION ZONE.

Claim 2

A METHOD FOR CONVERTING RELATIVELY HIGH-BOILING HYDROCARBON FEED MATERIALS IN THE PRESENCE OF FINELY DIVIDED FLUIDIZABLE SOLID MATERIAL WHICH COMPRISES PASSING AT LEAST ONE FIRST CONFINED STREAM OF SOLIDS AS A SUSPENSION SUBSTANTIALLY VERTICAL UPWARDLY FROM A REGENERATION ZONE UNDER ELEVATED TEMPERATURE CONVERSION CONDITIONS INTO A REACTION ZONE, INTRODUCING A HYDROCARBON REACTANT INTO ONE OF A SERIES OF INLET POINTS IN SAID FIRST CONFINED STREAM, DISCHARGING SAID FIRST CONFINED STREAM IN SAID REACTION ZONE ABOVE A DENSE FLUIDIZED BED OF SOLID MATERIAL THEREIN UNDER CONDITIONS TO SEPARATE SOLID MATERIAL FROM HYDROCARBON PRODUCT MATERIAL BY SETTLING, PASSING AT LEAST ONE SECOND CONFINED STREAM OF SOLIDS AS A SUSPENSION SUBSTANTIALLY VERTICALLY UPWARDLY FROM SAID REGENERATION ZONE UNDER ELEVATED TEMPERATURE CONVERSION CONDITIONS TO THE LOWER PORTION OF SAID REACTION ZONE, INTRODUCING A HYDROCARBON REACTANT INTO AT LEAST ONE OF A SERIES OF INLET POINTS IN SAID SECOND CONFINED STREAMS, DISCHARGING FINELY DIVIDED SOLIDS AND HYDROCARBON MATERIAL FROM SAID SECOND CONFINED STREAM INTO SAID REACTION ZONE UNDER CONDITIONS TO SEPARATE FINELY DIVIDED SOLIDS, FROM HYDROCARBON, PASSING FINELY DIVIDED SOLIDS FROM SAID REACTION ZONE TO A STRIPPING ZONE FOR DOWNWARD FLOW THEREIN COUNTER-CURRENT TO STRIPPING GAS INTRODUCED TO THE LOWER PORTION THEREOF, PASSING SOLIDS FROM THE LOWER PORTION OF SAID STRIPPING ZONE AS A CONFINED STREAM DOWNWARDLY TO THE LOWER PORTION OF A REGENERATION ZONE, HEATING SAID SOLIDS IN A FLUID BED CONDITION IN SAID REGENERATION ZONE TO AN ELEVATED TEMPERATURE AND PASSING THE THUS HEATED SOLIDS TO SAID FIRST AND SECOND CONFINED STREAMS OF SOLIDS BEING PASSED TO SAID REACTION ZONE.
