      Van’t Hoff’s equation, dlnK/dT=Q/TR², is expressed as follows:  Any chemical reaction can be directed and accelerated in a certain direction by continuous and simultaneous external variations in pressure, temperature, and concentration, acting in a direction contrary to that of the corresponding variations caused by the desired reaction.  Brutzkus suggests that the desired variations in pressure, temperature, and concentration can easily be obtained by operating in a compressor constructed and operated substantially as a diesel engine.  Application of such a method for cracking or hydrogenation under various conditions (exothermic and endothermic reactions), for the treatment of petroleum, tar oils, turpentine, fats, sugars and molasses, cellulose compounds and coal, and for the synthesis of light oil from CO, CO₂, and H₂, is discussed and compared with corresponding processes at present in use or proposed.  Very high temperatures and pressure could be used, and catalyzers could be eliminated.
