    Abstract: Fossil fuels such as coal or oil are gasified by treatment under superatmospheric pressures with oxygen containing gasifying agents to produce a primary gas containing carbon monoxide and hydrogen. The primary gas is desulfurized and converted in increasing portion into methanol which is stored as the load on the power plant increases. 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.

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 A product mixture which contains methyl formate is withdrawn from the synthesis reactor and is cooled to temperatures in the range from 20.degree.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 the production of methanol from gaseous hydrocarbons having a lower C/H ratio than is stoichiometrically required to produce methanol and comprising the steps of catalytically cracking said hydrocarbons in the presence of water vapor at about 830.degree. to 930.degree. C. and about 5 to 30 bars to produce a synthesis gas consisting essentially of hydrogen and oxides of carbon, and subsequently catalytically converting said synthesis gas of hydrogen and oxides of carbon to methanol at about 230.degree. to 280.degree. C. and about 30 to 150 bars, the improvement which comprises transferring heat from the hot synthesis gas to the hydrocarbon-water vapor mixture flowing through the cracking catalyst thereby providing at least part of the heat required for the catalytic cracking of the hydrocarbons and reducing the consumption of thermal-/energy per unit of methanol produced. Advantageously, heat transfer is effected by passing the hot synthesis gas through a convoluted or corrugated tube embedded in the hydrocarbon cracking catalyst. Gaseous carbon-containing constituents of the methanol synthesis exhaust gas are removed by adsorption, and desorption; CO.sub.2 may later be removed from the residual methanol synthesis exhaust gas by methanol scrubbing and subsequent stripping, both the desorbed constituents and the CO.sub.2 being mixed with the hydrocarbons before they are cracked, whereby the C/H ratio of the hydrocarbon feed is raised and the consumption of the thermal-/energy per unit of methanol produced is reduced.

C. and under a pressure of about 5-30 bars to produce a synthesis gas containing hydrogen and oxides of carbon, followed by a catalytic reaction of the hydrogen with the oxides of carbon at a temperature of about 230.degree.-280.degree. C. and under a pressure of about 30-150 bars to produce methanol, the improvement which comprises treating the methanol synthesis exhaust gas so as to remove therefrom carbonaceous gaseous constituents so that the residual gas is high in hydrogen, and adding said high-hydrogen residual gas to the hydrocarbons prior to cracking in an amount such that the C/H ratio of the material to be cracked is up to about 5.7, thereby reducing the energy consumption per unit of methanol produced. Advantageously, the cracking of said hydrocarbons is effected in two stages, the carbonaceous gaseous constituents removed from the methanol synthesis exhaust gas being used for indirect heating of the second cracking stage.

    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.
