Abstract

In accordance with a method of producing of methanol synthesis gas from a partial oxidation crude gas, the gas is cooled after a waste heat boiler of a gasifier by adding a converted circulating gas in a quenching zone. The resulting gas mixture is dedusted and then separated into a product gas partial stream and a circulating gas partial stream. The product gas partial stream is supplied after corresponding gas treatment to the synthesis reactor while the circulating gas partial stream is subjected to a CO-conversion and supplied back to the quenching zone.
