  • Patent number: 4839391
    Abstract: A single stage methanization reactor and process are made to yield a product gas of high methane content as well as useful superheated steam without overheating the catalyst bed in which a synthesis gas containing, CO, CO.sub.2 and H.sub.2 is converted into product gas. A variety of dispositions of vaporizer and superheater portions of the cooling system in the catalyst bed, for which the temperature profiles of gas and coolant along the reactor length are shown and compared, illustrate the principles governing the cooling system for such a reactor. A small portion of the superheated steam is mixed with preheated synthesis gas for elimination of all or part of the carbon monoxide content before the synthesis gas is introduced into the methanization reactor.

  • Patent number: 4431751
    Abstract: Only a part of the synthesis gas supply is passed through a first internally cooled catalytic reactor (1) and the hotter gas coming out of it is reunited with the remaining gas supply for passing through an adiabatic reactor (2) that is followed by a heat exchanger (3) on its way to a second internally cooled reactor (4) in which the methanization reaction is completed. Water is heated up to practically the saturated steam temperature in the cooling system of the last mentioned reactor and is converted to saturated steam in the cooling system of the first internally cooled reactor. The saturated steam is superheated in the above-mentioned heat exchanger. To make the process run more smoothly a steam drum is provided through which the hot water piping between the cooling systems of the two internally cooled reactors runs and the saturated steam is brought into the steam drum and from it to the heat exchanger before it is superheated.
