Abstract
An endothermic gas generator having separate sources of oxygen and hydrocarbon gas at pressures above the pressure of the endothermic gas to be produced, the sources of oxygen and hydrocarbon gas being interconnected through separate pressure reducing valves and to a gas tight reaction chamber, the reaction chamber containing catalyst bodies and being heated to a temperature sufficient to support a reaction between carbon atoms and oxygen atoms to produce an endothermic gas, the reaction chamber having a outlet port for an endothermic gas resulting from the reaction of the oxygen and the hydrocarbon gases at a pressure approximately that of the mixture of gases entering the reaction chamber. The outlet port of the endothermic gas generator is directly connected to a plenum chamber at the bottom of a reactor having a perforated plate confronting the plenum chamber and a porous ceramic layer disposed between the perforated plate and a chamber within the reactor, the reactor having a heat source and a bed of heat resistant granules maintained in a fluidized state by the flow of endothermic gas.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
