is very efficient and inexpensive but requires sophisticated equipment, in particular the apparatus for the treatment of an exhaust gas. A further disadvantage of the known process is that the treatment and disposal of the soot dust present in the process exhaust gases causes considerable expense. In the exhaust gas treatment, the soot dust should be cooled and the moisture removed before this soot dust is disposed of. A process for the production of methanol and the synthesis of hydrogen cyanide (U.S. Pat. No. 3,720,743, K. K. Manley, 1976) which is not cited in the original publication of the two patents just mentioned is described in an article by Manley and Smith in the Australian Journal of Chemistry, 9 (1977), Pages 257-262. The process involves the hydrolysis of a mixture of carbon monoxide and hydrogen in the presence of a catalytic composite consisting of a supported noble metal on an acidic support material. This is followed by the reaction of the hydrolyzed carbon monoxide and hydrogen with aqueous ammonia to give methanol and hydrogen cyanide. A process for producing ammonia from nitrogen by reduction of nitrogen monoxide with hydrogen is known from U.S. Pat. No. 3,454,591 (A. G. Kezer). According to the teaching of this reference, nitrogen monoxide and hydrogen are reacted at a temperature of 350.degree. to 750.degree. C. and at a pressure of 50 to 250 atm in the presence of a supported catalyst which comprises palladium metal on an alkali metal oxide support material. This catalyst, which is known to be effective in the production of ammonia from nitrogen monoxide and hydrogen, is used for continuous operation at a temperature of 450.degree. to 550.degree. C. at a pressure of 100 to 250 atm and a space velocity of 1000 to 5000 hr.sup.-1. The German patent No. 2,800,908 (A. L. Pezerat and R. Wernet) describes the production of methanol by reaction of carbon monoxide and hydrogen, the reaction product containing water in the form of steam. The reaction takes place in the presence of a catalyst which comprises the metal rhenium as the active component. The reaction is carried out at a temperature of 500.degree. to 1200.degree. C. and at a pressure of 2 to 80 atm, preferably in the presence of a cooling gas which consists of hydrogen.
