<p>In a process for obtaining CO, desulfurized natural gas or gas which accompanies mineral oil is reformed autothermally with addition of oxygenous gas at a temperature of from 900 to 1200°C and a pressure of from 40 to 100 bar (a) by partial catalytic oxidation to give a crude synthesis gas, and then converted catalytically to H and CO at a temperature of from 75 to 110°C and a pressure of from 50 to 75 bar (a) of CO, CO is scrubbed out of the synthesis gas obtained with methanol at a pressure of from 15 to 100 bar (a) and a temperature of from +10 to -80°C, and the absorbed CO is recovered by decompression. A further possible use of the process consists in converting the recovered CO to the supercritical state.</p> |
