Acetylene and ethylene are produced by passing high pressure well gas (comprising mainly methane) through a wave reactor containing hydrogen at a pressure lower than that of the well gas, whereby pressure interchange takes place, and passing the resulting mixture, in which the well gas is at a lower pressure than the hydrogen, through a second wave reactor. The original well gas will normally be at a pressure in the range 600-10,000 p.s.i., and during the reaction the temperature rises rapidly to at least 3200 DEG F. The wave reactor is described in detail (see Division B1).ALSO:Carbon disulphide, carbon monoxide, sulphur and other chemicals can be prepared from well gas in a shock tube reactor. The open-ended shock tube (71) rotates within and in the plane of a stationary port ring (24) having driving gas inlets (28), driving gas outlets (5, 6, 7 ...). arcuately elongated well gas inlet manifold (45) and arcuately elongated product gas outlet manifold (55). In operation, in each half-revolution of the shock tube, well gas is compressed in the tube by means of the driving gas, for example hydrogen. The process gases reach a temperature of 3200 DEG F. and the driving gas a pressure of 40 atmospheres. The reactions involved are CH4 + H2S --> CS2 CO2 + H2S --> CO + S + H2O The reactor may also be used to produce HCN from CH4 and N2.ALSO:Methanol and/or formaldehyde may be prepared at the well site from high pressure oil well gas which contains inter alia methane and oxygen using a shock-wave reactor of novel structure which is described in detail (see Division B1).
