    Abstract: Gasifying liquid hydrocarbon fuels, and in particular liquid heavy hydrocarbon fuels, at high fuel-to-air equivalence ratios with no significant soot formation comprises the steps of mixing the fuel and heated air in a prevaporization and mixing zone to prevaporize only a portion of the liquid fuel using only the sensible heat in the air, passing the partially vaporized fuel-air mixture through a catalyst zone to catalytically combust at least some of the prevaporized portion of the fuel while simultaneously, without the use of an external heat source, vaporizing and gasifying as-yet unvaporized fuel using the additional heat generated by the catalytic combustion, wherein the length of the catalyst zone, the catalyst configuration, and the fuel flow rate have been preselected to obtain the desired amount of gasification and to sustain continuous gasification with no significant soot formation.

    Abstract: An apparatus and process for producing a combustible oil gas as a supplement to heating gas from a gas generator comprising a bed of curved elongated refractory bodies composed of silicon carbide material having a high thermal conductivity superimposed upon a layer of refractory grid tile capable of withstanding over 3,000* F., the bed being of a thickness of 0.05-0.5 times the diameter of the shell of the gas generator containing the refractory bed, each body having a curved surface with a diameter between 0.5 to 0.08 times the bed thickness and a length approximately 0.2 to 1.0 times the bed thickness, the bed being directly exposed to form the bottom of a combustion chamber within the gas machine so as to absorb thermal shock and to preserve the conventional refractory brick tile from fusing and spalling and restricting the flow of gas through the refractory bed as well as to maintain a rapid heating oil ignition to avoid explosions within the refractory bed.

    Abstract: The compound Ni.sub.5 MgAl.sub.2 (OH).sub.16.sup.. CO.sub.3.sup.. 4H.sub.2 O is precipitated from an aqueous solution containing salts of nickel, magnesium and aluminum with a carbonate or bicarbonate of an alkali metal. After this catalyst precursor has been dried, calcined and reduced with hydrogen a catalyst can be prepared which is suitable for the cracking of hydrocarbons in the presence of steam. In the steam cracking of hydrocarbons the hydrocarbon and the steam may be reacted to form a gas rich in methane in contact with this catalyst at a preheating temperature of less than 300.degree. C.

    Abstract: Methane is produced by reacting a feed gas containing carbon oxides and hydrogen catalytically at an outlet temperature in the range 250-450.degree.C in heat exchange with boiling water generating steam at high pressure or in co-current heat exchange with coal feed gas, whereby heat is continuously removed from the process. By operating such a process in conjunction with a process of reacting hydrocarbons of higher molecular weight than methane with steam a natural gas substitute can be produced very economically.

    Abstract: A unitary, multiple-stage reaction system for countercurrently contacting a fluid reactant stream with catalyst particles movable through the system via gravity-flow. The reaction zones, or stages, are vertically stacked in a single chamber wherein catalyst particles flow from one annular-form bed to the next lower annular-form bed. A first portion of the hydrocarbonaceous charge stock flows downwardly into the lowermost reaction zone, laterally (outward to inward flow) through the annular-form catalyst bed into a center reactant conduit, is admixed with the second portion of the charge stock, flows upwardly through the reactant conduit into the next upper zone and laterally (inward to outward flow) through the annular-form catalyst bed. A preferred embodiment involves three reaction zones within the reaction chamber, with heat-exchange provisions between the middle and upper zones.

    Abstract: A physically durable catalyst composition having high and longlived catalytic activity comprising calcium aluminate and nickel promoted with a barium salt of an organic acid is provided. The catalyst is preferably prepared by impregnating the calcium aluminate support with a nickel salt, reducing the nickel saltimpregnated calcium aluminate and then adding the barium salt, followed by drying prior to use. The catalyst has utility in the steam reforming of hydrocarbons to produce gaseous products rich in methane, fungible with natural gas.
