<p>A gas with a hydrogen content of at least 85 volume percent of partial oxidation crude gas is produced in a method including cooling of the gas after waste heat boiler of a gasifier by adding converted circulating gas in a quenching zone. The resulting gas mixture after corresponding gas treatment is subjected to a CO-conversion and then separated into a circulating gas partial stream and a product gas partial stream. The circulating gas partial stream is supplied back after a corresponding compression to the quenching zone, while the product gas partial stream after a so-called acid gas washing is subjected to a further gas treatment in correspondence with a desired use.</p> |
