Apparatus for catalytically cracking hydrocarbons

Claim 1

AN APPARATUS FOR CATALYTICALLY CRACKING HYDROCARBON MATERIAL COMPRISING IN COMBINATION, A REACTOR-SEPARATOR CHAMBER SITUATED ABOVE A REGENERATOR CHAMBER, SAID REACTOR-SEPARATOR CHAMBER BEING OF LARGER DIAMETER IN THE UPPER PORTION THEREXX THAN IN THE LOWER PORTION, A SUBSTANTIALLY VERTICAL FIRST RISER CONDUIT EXTENDING UPWARDLY FROM WITHIN THE LOWER PORTION OF SAID REGENERATOR CHAMBER INTO AND TERMINATING IN THE LOWER PORTION OF SAID REACTOR-SEPARATOR CHAMBER TO FORM AN ANNULAR SPACE THEREWITH, THE TERMINUS OF SAID FIRST RISER, CONDUIT BEING CAPPED WITH A PERFORATED BAFFLE MEMBER, AT LEAST ONE SECOND RISER CONDUIT EXTENDING SUBSTANTIALLY VERTICALLY UPWARDLY FROM WITHIN THE LOWER PORTION OF SAID REGENERATOR CHAMBER INTO THE UPPER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, AN ANNULAR STRIPPING CHAMBER POSITIONED BETWEEN SAID REACTOR-SEPARATOR CHAMBER AND SAID REGENERATOR CHAMBER AND HAVING A MAXIMUM DIAMETER SUBSTANTIALLY EQUAL TO THE DIAMETER OF THE LOWER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, A FIRST CONDUIT MEANS PROVIDED WITH A VALVE MEANS IN THE LOWER PORTION THEREOF EXTENDING DOWNWARDLY FROM THE LOWER PORTION OF SAID ANNULAR SPACE INTO ONE SAID OF SAID ANNULAR STRIPPING CHAMBER, A SECOND CONDUIT MEANS COMMUNICATING BETWEEN THE OPPOSITE SIDE OF SAID ANNULAR STRIPPING CHAMBER FROM SAID FIRST CONDUIT MEANS AND THE LOWER PORTION OF A REGENERATOR CHAMBER, SEPARATE MEANS FOR INTRODUCING GASEOUS MATERIAL TO THE LOWER PORTION OF SAID ANNULAR SPACE AND SAID ANNULAR STRIPPING CHAMBER, MEANS FOR INTRODUCING SUBDIVIDED CONTACT MATERIAL WITHDRAWN FROM SAID REGENERATOR CHAMBER WITH A FIRST REACTANT MATERIAL INTO THE BOTTOM PORTION OF SAID FIRST RISER CONDUIT, MEANS FOR INTRODUCING SUBDIVIDED CONTACT MATERIAL WITHDRAWN FROM SAID REGENERATOR CHAMBER WITH A SECOND REACTANT MATERIAL INTO THE BOTTOM PORTION OF SAID SECOND RISER CONDUIT, AT LEAST ONE OPEN END CONDUIT COMMUNICATING BETWEEN THE UPPER PORTION OF SAID ANNULAR STRIPPING CHAMBER AND THE UPPER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, AND MEANS FOR REMOVING GASEOUS MATERIAL FROM THE UPPER PORTION OF EACH OF SAID REGENERATOR CHAMBER AND SAID REACTOR-SEPARATOR CHAMBER.

Claim 2

AN APPARATUS FOR CATALYTICALLY CRACKING HYDROCARBON MATERIAL COMPRISING IN COMBINATION, A REACTOR-SEPARATOR CHAMBER SITUATED ABOVE A REGENERATOR CHAMBER, SAID REACTOR-SEPARATOR CHAMBER BEING OF LARGER DIAMETER IN THE UPPER PORTION THEREXX THAN IN THE LOWER PORTION, A SUBSTANTIALLY VERTICAL FIRST RISER CONDUIT EXTENDING UPWARDLY FROM WITHIN THE LOWER PORTION OF SAID REGENERATOR CHAMBER INTO AND TERMINATING IN THE LOWER PORTION OF SAID REACTOR-SEPARATOR CHAMBER TO FORM AN ANNULAR SPACE THEREWITH, THE TERMINUS OF SAID FIRST RISER, CONDUIT BEING CAPPED WITH A PERFORATED BAFFLE MEMBER, AT LEAST ONE SECOND RISER CONDUIT EXTENDING SUBSTANTIALLY VERTICALLY UPWARDLY FROM WITHIN THE LOWER PORTION OF SAID REGENERATOR CHAMBER INTO THE UPPER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, AN ANNULAR STRIPPING CHAMBER POSITIONED BETWEEN SAID REACTOR-SEPARATOR CHAMBER AND SAID REGENERATOR CHAMBER AND HAVING A MAXIMUM DIAMETER SUBSTANTIALLY EQUAL TO THE DIAMETER OF THE LOWER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, A FIRST CONDUIT MEANS PROVIDED WITH A VALVE MEANS IN THE LOWER PORTION THEREOF EXTENDING DOWNWARDLY FROM THE LOWER PORTION OF SAID ANNULAR SPACE INTO ONE SAID OF SAID ANNULAR STRIPPING CHAMBER, A SECOND CONDUIT MEANS COMMUNICATING BETWEEN THE OPPOSITE SIDE OF SAID ANNULAR STRIPPING CHAMBER FROM SAID FIRST CONDUIT MEANS AND THE LOWER PORTION OF A REGENERATOR CHAMBER, SEPARATE MEANS FOR INTRODUCING GASEOUS MATERIAL TO THE LOWER PORTION OF SAID ANNULAR SPACE AND SAID ANNULAR STRIPPING CHAMBER, MEANS FOR INTRODUCING SUBDIVIDED CONTACT MATERIAL WITHDRAWN FROM SAID REGENERATOR CHAMBER WITH A FIRST REACTANT MATERIAL INTO THE BOTTOM PORTION OF SAID FIRST RISER CONDUIT, MEANS FOR INTRODUCING SUBDIVIDED CONTACT MATERIAL WITHDRAWN FROM SAID REGENERATOR CHAMBER WITH A SECOND REACTANT MATERIAL INTO THE BOTTOM PORTION OF SAID SECOND RISER CONDUIT, AT LEAST ONE OPEN END CONDUIT COMMUNICATING BETWEEN THE UPPER PORTION OF SAID ANNULAR STRIPPING CHAMBER AND THE UPPER PORTION OF SAID REACTOR-SEPARATOR CHAMBER, AND MEANS FOR REMOVING GASEOUS MATERIAL FROM THE UPPER PORTION OF EACH OF SAID REGENERATOR CHAMBER AND SAID REACTOR-SEPARATOR CHAMBER.
