Abstract
A process for carrying out highly endothermic chemical reactions wherein a reactive metal or a compound thereof is reacted with a source of carbon to form a carbon-containing derivative, preferably a carbide, in the presence of a molten metal. The sensible heat of the molten metal supplies the energy necessary for the reaction.
Claims7
A process for producing carbides of reactive metals comprising:
- (a) forming, in a first reaction zone, a molten metal selected from the group consisting of iron and copper by combustion of a fuel,
- (b) passing the molten metal from the first reaction zone to a second reaction zone,
- (c) supplying to said second zone a reactive metal source selected from the group consisting of alkali metals and alkaline earth metals and the carbonates, oxides and hydroxides thereof and a carboneaceous fuel wherein the sensible heat of the molten metal supplies the heat required to react said reactive metal source with said fuel to form a carbide of the reactive metal, which floats on the surface of the molten metal and
- (d) separating the metal carbide and the molten metal.
