Fludized solids reactor

Claim 1

IN A REACTOR FOR CONTACTING A GASIFORM REACTANT STREAM WITH A DENSE FLUID PHASE, SOLID PARTICLE MATERIAL, A VERTICAL REACTION VESSEL DIVIDED BY UPPER AND LOWER TUBE SHEETS INTO A LOWER TEMPERATURE-REGULATING FLUID RESERVOIR, A CENTRAL REACTION CHAMBER AND AN UPPER TEMPERATURE-REGULATING FLUID RESERVOIR, A PLURALITY OF PARALLEL, VERTICAL TUBES PASSING THROUGH SAID CENTRAL REACTION CHAMBER FROM THE LOWER TUBE SHEET TO THE UPPER TUBE SHEET AND COMMUNICATING WITH SAID RESERVOIRS, THE UPPER TUBE SHEET BEING DISPOSED IN A HORIZONTAL PLANE AT RIGHT ANGLES TO SAID VERTICAL TUBES, THE LOWER TUBE SHEET FORMING A SUBSTANTIAL ANGLE WITH THE HORIZONTAL EQUAL AT LEAST TO THE ANGLE OF REPOSE OF THE SOLID PARTICLE MATERIAL, MEANS FOR INTRODUCING THE GASIFORM REACTANT STREAM INTO THE REACTION CHAMBER JUST ABOVE THE LOWER TUBE SHEET SUBSTANTIALLY UNIFORMLY SUBSTANTIALLY ALONG ITS LOWEST ELEVATION WITHIN THE VESSEL WITHOUT PASSING THROUGH SAID LOWER TUBE SHEET, MEANS FOR WITHDRAWING EFFLUENT REACTION PRODUCTS FROM THE UPPER PORTION OF SAID REACTION CHAMBER BELOW THE UPPER TUBE SHEET AND WITHOUT PASSING THROUGH SAID UPPER TUBE SHEET, MEANS FOR SUPPLYING TEMPERATURE-REGULATING FLUID TO ONE OF SAID RESERVOIRS TO CIRCULATE THROUGH THE SAID VERTICAL TUBES, MEANS FOR REMOVING SAID FLUID FROM THE OTHER OF SAID RESERVOIRS AND MEANS FOR INTRODUCING SAID SOLID PARTICLE MATERIAL AND WITHDRAWING IT FROM SAID CENTRAL REACTION CHAMBER WITHOUT PASSING THROUGH SAID TUBE SHEETS.
