  • Shell-and-tube reactor for carrying out catalytic gas phase reactions
    Patent number: 8961909
    Abstract: A tube bundle reactor for carrying out catalytic gas phase reactions, particularly methanation reactions, has a bundle of catalyst-filled reaction tubes through which reaction gas flows and around which heat carrier flows during operation. In the region of the catalyst filling, the reaction tubes run through at least two heat carrier zones which are separated from one another, the first of which heat carrier zones extends over the starting region of the catalyst filling. The reaction tubes each have a first reaction tube portion with a first hydraulic diameter of the catalyst filling and, downstream thereof in flow direction of the reaction gas, at least a second reaction tube portion with a second hydraulic diameter of the catalyst filling that is greater than the first hydraulic diameter of the catalyst filling.

  • METHOD FOR PRODUCING A METHANE-RICH PRODUCT GAS AND REACTOR SYSTEM USABLE FOR THAT PURPOSE
    Publication number: 20130041051
    Abstract: The invention relates to a method for producing a methane-rich product gas, in which a starting gas containing hydrogen and carbon dioxide is catalytically methanated under the influence of at least one adjustatable parameter in at least two stages and at least one criterion relating to the composition of the product gas is monitored. The criterion is fulfilled under a condition influencing the method and when the condition changes, a change in the parameter setting that preserves fulfilment of the criterion is affected.
