Process for securing chemicals from petroleum residua

Claim 1

A HYDROCARBON CONVERSION PROCESS FOR THE PRODUCTION OF CHEMICALS WHICH COMPRISES CONTACTING A HEAVY HYDROCARBON OIL CHARGING STOCK WITH A STREAM OF HIGH TEMPERATURE SUBSTANTIALLY CATALYTICALLY INERT PARTICULATE SOLIDS IN A CONVERSION ZONE AT A TEMPERATURE IN THE RANE OF 1200* TO 2000*F., RAPIDLY SEPARATING AND WITHDRAWING GASIFORM CONVERSION PRODUCTS AND INTRODUCING THE CONVERSION PRODUCTS INTO AN INTERMEDIATE PORTION OF AN EXTRANEOUS HEAT EXTRACTION ZONE, DOWNWARDLY PASSING RELATIVELY COOL, SUBSTANTIALLY NON-ENTRAINABLE, PARTICULATE SOLIDS COUNTERCURRENT TO SAID CONVERSION PRODUCTS IN SAID HEAT EXTRACTION ZONE WHEREBY SAID CONVERSION PRODUCTS ARE COOLED DEPOSITING CONDENSATE ON SAID RELATIVELY COOL PARTICULATE SOLIDS, WITHDRAWING RELATIVELY COOL CONVERSION PRODUCTS OVERHEAD FROM SAID ZONE, COLLECTING PARTICULATE SOLIDS IN A LOWER SEGREGATED PORTION OF SAID HEAT EXTRACTION ZONE, LONG TERM CONVERSION PRODUCTS BEING SEPATATELY WITHDRAWN FROM SAID SEGREGATED PORTION, THE SOLIDS REMAINING RESIDENT IN SAID SEGREGATED PORTION AT A TEMPERATURE IN THE RANGE OF 1000* TO 1700*F., AND FOR A TIME SUFFICIENT TO SUBSTANTIALLY COMPLETELY CONVERT THE CONDENSATE THEREON AND TO DRY SAID SOLID, COOLING AND STRIPPING SOLIDS FROM THE LOWER PORTION OF SAID HEAT EXTRACTION ZONE IN AN ENLARGED SETTLING ZONE AND RECIRCULATING THEM TO THE UPPER PORTION OF THE HEAT EXTRACTION ZONE AS SAID RELATIVELY COOL PARTICULATE SOLIDS, AND REHEATING AND RETURNING SOLIDS SEPARATED FROM SAID CONVERSION PRODUCTS TO SAID CONVERSION ZONE.
