Abstract: A process for the selective production of partially oxidized organic compounds at the catalytic anode of a fuel cell wherein oxide anions formed at the fuel cell cathode by ionization of oxygen containing gas are transported by a molten salt oxygen containing electrolyte to the catalytic anode where selective partial oxidation of organic compounds is facilitated by the catalytic anode. Suitable catalytic anodes include catalysts selected from elements of the Periodic Table appearing in a group selected from the group consisting of Group IB, IIB, IIIA, VB, VIB, VIIB and VIII, in metallic oxide or cermet form. The process of this invention is particularly useful in the production of methanol by partial oxidation of methane.

Abstract: An apparatus for withdrawing agglomerated solids, e.g. ash, from a fluidized bed of finely divided solid hydrocarbonaceous material, e.g. coal, is described. Agglomeration is effected by a high temperature reaction between the inorganic constituents of the hydrocarbonaceous material in the fluidized bed environment. A venturi is utilized to serve as a passage for withdrawing the agglomerated solids from the fluidized bed. Spiral or other descending ridges are positioned on the interior surface of the constricted cylindrical opening of the venturi to permit variable and increased rates of agglomerate discharge with improved separation and classification of the solid materials.

A tube, through which reaction gases pass, is centrally disposed within the constricted cylindrical opening to permit variable and increased rates of agglomerate discharge with improved separation and classification of the solid materials.
