Abstract
Hydrocarbons are formed by subjecting a steady or intermittent flow of a mixture of carbon monoxide and hydrogen to thrusts of shock waves periodically passing through the mixture at supersonic speed (see Group III).ALSO:<PICT:0737555/III/1> <PICT:0737555/III/2> Chemical reactions are performed by a subjecting a steady or intermittent flow of a non-detonating mixture of the reactants in gaseous or aerosol form to thrusts of shock waves periodically passing through the mixture at supersonic speed. In the apparatus shown in Fig. 3 the reactants enter at 8 and leave at 10, the shock waves produced being reflected at the surface 11 and returning through the reaction space as a convergent wave front. In the apparatus of Fig. 5 the reactants flow from 25 to 26 as a thin layer adjacent the wall 27 and are acted on by shock waves produced in the casing 24; additional energy is supplied by an electromagnetic oscillating device 19, 20 which intensifies the shock waves; the space in the casing outside the actual reaction zone may be filled with a gas of specific gravity lower than that of the reactants. Catalyst may be attached to the walls of the reaction zone or suspended in the reactants. Additional exothermically reacting substances (e.g. a mixture of fuel and air) may be added to the reactants to produce or intensify the shock waves or to provide a higher temperature. Reactions may be carried out at pressures above atmospheric, and may be controlled so as to obtain intermediate products. In examples, mixtures of coal dust and air are introduced through a restricted inlet at one end of a tube open at the other end, shock waves being formed at the outlet from the tube and passing back through the reactants; gas containing carbon dioxide, carbon monoxide, hydrogen and nitrogen is produced. Reactions between carbon monoxide and hydrogen to form hydrocarbons and between nitrogen and hydrogen in the presence of catalyst to form ammonia are also referred to.
