Claim 3
Dependent Claim
212 words
A PROCESS FOR THE CONVERSION OF HYDROCARBONS WHICH COMPRISES HEATING PEBBLES IN A FIRST CHAMBER TO A TEMPERATURE WITHIN THE RANGE OF BETWEEN 1200* F. AND 2800* F., GRAVITATING SAID HOT PEBBLES INTO AND THROUGH A SECOND CHAMBER; CONTACTING SAID HOT PEBBLES AND HYDROCARBON REACTANT MATERIALS IN DIRECT HEAT EXCHANGE IN SAID SECOND CHAMBER; RAISING SAID HYDROCARBON REACTANT MATERIALS TO CONVERSION TEMPERATURE BY SAID DIRECT HEAT EXCHANGE; REMOVING RESULTING CONVERSION PRODUCTS FROM THE UPPER PORTION OF SAID SECOND CHAMBER; BLANKETING THE UPPER SECTION OF SAID SECOND CHAMBER WITH A BLANKET OF AN INERT GAS INTRODUCED AS A THIN ANNULAR BLANKET WITHOUT SUBSTANTIAL TURBULENCE FROM SOURCES AT THE INTERIOR AND AT THE EXTERIOR OF SAID ANNULAR BLANKET, SAID INERT GAS SOURCES BEING MAINTAINED AT A PRESSURE WITHIN THE RANGE OF BETWEEN 10 TO 70 P. S. I. AND AT A RELATIVELY HIGH VELOCITY AS COMPARED TO SAID CONVERSION PRODUCTS, SO AS TO SEPARATE SAID CONVERSION PRODUCTS FROM THE INNER SURFACE OF THE UPPER PORTION OF SAID SECOND CHAMBER BY SAID RELATIVELY HIGH VELOCITY BLANKET OF SAID INERT GAS; REMOVING SAID INERT GAS FROM THE UPPER PORTION OF SAID SECOND CHAMBER WITH SAID CONVERSION PRODUCTS; REMOVING SAID PEBBLES FROM THE LOWER PORTION OF SAID SECOND CHAMBER; AND RETURNING SAID PEBBLES TO SAID FIRST CHAMBER.
