2783.  ROBERTS, G., JR. (M.W. Kellogg Co.).  Apparatus for Endotherrmic Catalytic Reactions  Such as Carbon Monoxide and Hydrogen Production From Methane , Carbon Dioxide, and Water.  United States Patent 2,335,753, Aug. 15, 1944; appl. filed Mar. 20, 1940, Serial No. 324,899; 4 claims (Cl. 23-288).  Chem. Abs., vol. 39, 1945, p.164.

Apparatus is employed for use of a porous catalytic mass, such as one containing Ni on fire clay or alundum at elevated temperature, such as 1,800°-2,200° F., for the production of CO and H2 from gaseous reactants, such as CH4, CO2, and H2O and adapted to operate on alternating conversion and heat-regenerative cycles, that comprises a chamber having a contact mass in loose aggregate form disposed in the interior and openings in the side wall of the chamber for introducing a fuel gas into it, conduits imbedded in and supported by this mass in substantially horizontal planes and having apertures at suitably spaced intervals throughout their length for the introduction of the fuel gas into the mass, the ends of these conduits being abutted against the side walls of the chamber and arranged in fluid-intercommunicating relationship with the wall openings and being nonrigidly and movably associated with the wall of the chamber, so that the conduits are capable of limited movement relative to the wall without interruption of the flow of fuel gas through the conduits
