Synthesis gases containing carbon monoxide, eg above 40% volume, and hydrogen are methanated to produce substitute natural gas, after CO2 removal, wherein the synthesis gas is simultaneously saturated with water, further heated and divided into first and second feed gas streams. The first feed gas stream is catalytically methanated at a temperature of from 250 to 550°C, and the reaction product mixed with said second feed gas stream. The mixture is methanated over a second catalyst at a temperature of from 250 to 550°C and the product is divided into a second product gas stream and a recycle gas stream and the recycle gas stream is admixed with the first feed gas stream, prior to the first catalytic methanation. The second product gas stream is subjected to a carbon dioxide removal process to produce SNG.
A process for producing a methane containing substitute natural gas from a primary synthesis gas containing more than 40 percent by volume of carbon monoxide on a dry basis and hydrogen comprising the steps of: simultaneously heating and saturating said primary synthesis gas with water; heating the
A process for producing a methane containing substitute natural gas from a primary synthesis gas containing more than 40 percent by volume of carbon monoxide on a dry basis and hydrogen comprising the steps of: simultaneously heating and saturating said primary synthesis gas with water; heating the saturated synthesis gas further and dividing the same into first and second feed gas streams; admixing a recycle gas stream from the product gas of second concurrent shift and methanation reactions with the first feed gas stream and subjecting the admixture to first concurrent shift and methanation reactions over a catalyst at a temperature of from 250°to 550°C.; mixing the product of the first reactions with said second feed gas stream and effecting second concurrent shift and methanation reactions on said mixture over a second catalyst at a temperature of from 250°to 550°C.; dividing the product of the second reactions into a second product gas stream and said recycle gas stream; and subjecting said second product gas stream to a carbon dioxide removal process.
