Abstract: Methanol is catalytically produced from a synthesis gas which contains H.sub.2, CO and CO.sub.2 in a synthesis reactor at temperatures from 220.degree. to 300.degree. C. and under a pressure in the range from 20 to 120 bars. A product mixture which contains methyl formate is withdrawn from the synthesis reactor and is cooled to temperatures in the range from 20.degree. to 60.degree. to provide a condensate which contains methanol, water and methylformate. A gas mixture which contains H.sub.2, CO and CO.sub.2 is formed at the same time. A fraction which comprises 10 to 100% by weight methyl formate is separated from the condensate and is admixed with the synthesis gas which is fed to the synthesis reactor.

Abstract: In a reforming reactor operated with reactor outlet temperatures from 600.degree. to 1300.degree. C. and under a pressure from 10 to 100 bars, a methane-containing hydrocarbon gas is reacted with oxygen and water vapor. The reforming reactor is additionally fed with a high-hydrogen gas, which contains free hydrogen. The raw synthesis gas withdrawn from the reforming reactor is mainly composed of hydrogen, carbon monoxide and carbon dioxide. Without a removal of carbon dioxide from the raw synthesis gas, a synthesis gas is produced, which is suitable for the methanol synthesis and in which the concentrations of the components H.sub.2, CO and CO.sub.2 have a molar ratio (H.sub.2 -CO.sub.2): (CO+CO.sub.2), called the stoichiometric number, from 1.97 to 2.2. In case of need, the stoichiometry number can be adjusted by adding hydrogen to the raw synthesis gas coming from the reforming reactor.

Abstract: Gases which are rich in carbon monoxide are producted by a catalytic cracking of gaseous or vaporized hydrocarbons. A part of the hydrocarbons is combusted with an oxygen-containing gas which is added at a rate that is twice to ten times the stoichiometric oxygen demand. The combustion temperature are between 800.degree. and 1500.degree. C. The oxygen-containing combustion gas is admixed to the preheated remainder of the hydrocarbon and a mixture is producted which is at a temperature between about 700.degree. and about 1300.degree. C. That mixture is passed through a fixed bed consisting of a granular cracking catalyst. A high-CO product gas at a temperature between about 800.degree. and about 1150.degree. C. is withdrawn from the fixed bed.

An increasing proportion of the stored methanol is used in addition to desulfurized primary gas in the power plant as the load on the power plant increases.
