发明名称 PROCESS FOR RECOVERING CARBON DIOXIDE
摘要 In a process for obtaining CO2, 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 H2 and CO2 at a temperature of from 75 to 110 DEG C. and a pressure of from 50 to 75 bar (a) of CO, CO2 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 CO2 is recovered by decompression. A further possible use of the process consists in converting the recovered CO2 to the supercritical state.
