摘要： A process for manufacturing methanol is disclosed, wherein the pressure in the step of preparation of the synthesis gas is selected equal to the pressure in the step of preparation of methanol from the synthesis gas. The operation efficiency of the process is maintained by recycling the methanol-free recycle stream to the reaction zone for methanol synthesis notwithstanding the lower pressure in the step of methanol synthesis.

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.

摘要： Methanol is produced by passing a mixture of hydrogen and one or more carbon oxides into contact with at least two beds (converters) of catalyst arranged in series, the beds of catalyst being operated at increasing temperature levels in the direction of flow of the mixture. The mixture is then cooled by indirect heat-exchange and passed into contact with at least one further bed of catalyst.

摘要： An economical, efficient process is provided employing coal, particularly subbituminous coal, as a fuel source for the production of distillate fuels, methanol, and methane. A hydroliquefier is operated under severe conditions to provide a high net yield of light distillates which are separated by distillation. The vacuum residue, which is produced above, is transferred as a slurry to a partial oxidation gasifier where synthesis gas is produced as feedstock for methanol or methane synthesis. Gaseous hydrocarbon contaminants are separated and used to generate additional synthesis gas, or to supply other fuel requirements. No net heavy distillates are taken as a product, being used as a fuel or converted to other products.

摘要： A process for producing methanol from air-blown gasified coal. A feed gas stream obtained by the coal gasification step is combined with a recycle gas stream and fed to a reactor where carbon oxides are converted to methanol. Exit gas from the reactor is scrubbed to remove carbon monoxide, and the carbon monoxide-free exit gas is then chilled to remove all components except hydrogen. The hydrogen is then combined with the carbon monoxide and used as a recycle stream. The process enables use of an air-blown gasified coal stream while maintaining the nitrogen content in the reactor at an acceptably low level.
