摘要： A gas which can be substituted for natural gas is produced from a raw gas containing hydrogen and carbon oxides which is produced by the gasification of coal, tar or heavy residual oils under superatmospheric pressure. The raw gas is cooled, purified to remove catalyst poisons, particularly sulfur compounds, and then subjected to methanation and at least two stages in contact with nickel catalysts under pressures of 5-100 bars and at temperatures in the range of 200.degree.-500.degree. C. The product gas from the preceding methanation stage is reacted in the last methanation stage in contact with a catalyst which is indirectly cooled by a gas flowing in a countercurrent to the gas to be reacted.

摘要： 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.

摘要： A reducing gas useful for reducing ores containing carbon monoxide and hydrogen and low amounts of carbon dioxide and water vapor is produced by reacting gaseous and/or volatile liquid hydrocarbons with water vapor on an indirectly heated, nickel-containing catalyst under superatmospheric pressure. A partial amount of the hydrocarbons to be reacted is first cracked in contact with a nickel catalyst at 350.degree. - 500.degree.C. with at least part of the water vapor to form a hydrogen-containing gas, which is mixed with the remaining hydrocarbons. The mixture is further heated if desired and is then completely reacted at temperatures above 900.degree.C. in contact with the indirectly heated catalyst.

摘要： In the production of methanol from gaseous and liquid hydrocarbons having a higher C/H ratio than is stoichiometrically required to produce methanol, wherein said hydrocarbons are catalytically cracked in the presence of water vapor and at a temperature of about 350.degree.-950.degree. 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. The removal of the carbonaceous gaseous constituents from the methanol synthesis exhaust gas is effected by contacting such exhaust gas with a molecular sieve, at least part of the high-hydrogen residual gas being added to the hydrocarbons before the second stage, the mixture of hydrocarbons and high-hydrogen residual gas being treated to effect hydrogenation and desulfurization of the hydrocarbons.
