Methane is produced by reacting CO or CO2 with hydrogen in the presence of a catalyst in a so-called 'methanation' reaction. To mitigate problems of poisoning and/or ageing of catalytically active material, the catalyst is in the form of one or more discrete catalyst bodies, the or each body having a plurality of internal pathways of pre-determined dimensions and arrangement for reactant(s) and/or product(s) of the reaction and containing the catalytically active material for the reaction uniformly and homogeneously dispersed therethrough. The material may constitute more than 50% by weight and even substantially all of the or each body. The catalytically active material may, for example, be NiO/NiAl2O4. |
