Title: Methane-rich gas process
IPC: C10G9/38
Filed: 1974-12-23
Abstract: A methane-rich gas stream is produced by catalytic methanation of synthesis gas feed comprising H2 and CO. When the mole ratio H2/CO of the synthesis gas feed is in the range of about 0.5 to 1.15, by adjusting the mole % H2O in the synthesis gas feed to a value in the range of about 0.1 to 15., the gross heating value of the product gas may be increased to a value above that obtained with a dry substantially CO2-free methanator feed gas. This effect of adding H2O becomes more pronounced as the H2/CO ratio drops further below the maximum value of 1.13. Further, in a preferred embodiment the gross heating value of the product gas (with H2O and CO2 removed) was maximized by adjusting the mole % H2O in the synthesis gas feed to the methanator to a critical value in the range of 1.0 to 3.0 and preferably 2.0 while maintaining the H2/CO mole ratio of the synthesis gas feed at a critical value in the range of about 1 to 1.15 and preferably 1.13.
