摘要:
The present invention is a novel process for methanol production in a liquid phase reactor from a synthesis gas comprising of hydrogen, carbon dioxide and carbon monoxide. The liquid phase reactor contains a solid catalyst suspended in methanol. In this innovation, methanol acts both as a product and as a suspension medium for the catalyst. The new innovation exploits the condensing conditions for methanol production. By operating at condensing conditions, the methanol partial pressure at equilibrium is higher than the boiling pressure of methanol at the given temperature. Hence the produced methanol of the equilibrium composition condenses creating the potential of more gas to be converted. Since equilibrium is not a limiting factor, high conversions can be obtained.

摘要:
Process for the oxidation of a hydrocarbon substrate to a corresponding oxidised hydrocarbon compound by contacting the hydrocarbon substrate with an oxygen containing atmosphere in presence of a catalyst being active in the oxidation of the hydrocarbon substrate, which process comprises the steps of: passing a process gas containing the hydrocarbon substrate through a reaction zone with the catalyst; introducing the oxygen containing atmosphere divided into a plurality of substreams successively into the reaction zone; within the reaction zone reacting the process gas continuously with the oxygen containing atmosphere; and withdrawing from the reaction zone a product gas containing oxidised hydrocarbon compound and carbon monoxide.
