    摘要: A new technique for oxidizing a gaseous phase oxidizable feed involves a process wherein a gas mixture containing at least one oxidizing gas is placed in contact with an oxidizable feed inside a mixing contact zone situated between at least one first zone passed through by the feed and at least one second zone passed through by the oxidation reaction products. The first and second zones define a multiplicity of multidirectional spaces exhibiting passages having, along at least one direction, a dimension at most equal to the jamming distance of the flame possibly resulting from oxidations of feed. The contact zone comprises an oxidizing gas mixture supply means comprising a plurality of parallel pipes with porous walls situated at a distance from the first and second zones which is at most equal to the jamming distance.

    摘要: Process for converting solid carbonaceous materials to methane, comprising (a) converting the carbonaceous material by means of a reducing gas at 300.degree.-500.degree. C. to a semi-oily phase adapted to be pumped and atomized, (b) heating falling droplets of said semi-oily phase to a temperature of 700.degree.-1600.degree. C. with hot solid particles in downward jets in the presence of reducing gas, under a presssure above 20 bars, (c) separating the solid particles of large size (d), heating them and feeding them back to step (b), (e) cooling the remaining fraction consisting of gas and solid particles of small size by means of a cold reducing gas and separating methane therefrom, and (f) treating the remaining solid phase of fine particles with oxygen and steam to produce a reducing gas fed back to steps (a) and (b).
