A reactor is provided for producing methanol by the reaction of synthesis gases containing carbon oxides and hydrogen in contact with a copper containing catalyst positioned in the reactor in catalyst tubes surrounded by boiling water under pressure. The catalyst tubes are made from a metallic material which is catalytically inactive with respect to the methanol synthesis gas and have approximately the same coefficient of thermal expansion as the shell of the reactor. The catalyst tubes are made of a steel composed of mixed austeniticferritic structure and containing 10-30% by weight chromium.

A process for the selective removal of hydrogen sulfide from a gas containing hydrogen sulfide and carbon dioxide wherein said gas is contacted at superatmospheric pressure with an alkali metal carbonate solution, the resultant solution which contains hydrosulfide and bicarbonate is subjected to pressure reduction, the total alkali metal bicarbonate content of the resultant solution is adjusted so that it is at least 55% of the total alkali content of the solution and the said solution is then stripped and recycled to the hydrogen sulfide absorption step.

The gases discharged from the sulfur condenser of a Claus process reactor are contacted with an active adsorbent to remove further sulfur and the resulting exhaust gas is afterburned. A desorption gas is passed in closed cycle through the laden adsorbent and is heated, in this cycle, in heat exchange with the hot gases emerging from the afterburner. The sulfur is condensed from the desorption gas with the same cooling system used for the Claus process condensation and water vapor produced by the cooling system is condensed and by gravity is returned to the condensation stage.

Process for producing methanol

A reactor for the continuous gasification of coal under superatmospheric pressures and elevated temperatures with gaseous gasifying agents containing free oxygen and with oxygen-free gasifying agents such as steam and/or carbon dioxide is disclosed. The reactor includes a substantially conical rotary grate which is rotatably mounted in the lower portion of the reactor housing. The rotary grate feeds the gasifying agent and/or discharges the gasification residues. Notwithstanding the inside diameter of the reactor housing, the clearance a between the rotary grate and the housing is 100-200 millimeters, the height b of the annular rim of the rotary grate is 100-350 millimeters, and the vertical distance c from the rotary grate to the housing bottom is 100-350 millimeters.
