Abstract

A reactor for conducting an exothermic methanation reaction of carbon oxides, comprising: a cylinder (14, 24) defining a reaction chamber of variable volume and having at least one inlet channel (161, 171, 172, 261, 262) for introducing into the cylinder (14, 24) gaseous reactants of the methanation reaction, namely hydrogen and carbon monoxide and/or carbon dioxide, and at least one outlet channel (18, 281, 282) for removing reaction products from the cylinder (14, 24), a catalyst arranged to catalyse the exothermic methanation reaction of said reactants in the cylinder (14, 24), at least one piston (11, 211, 212) having a piston crown (111, 213, 214) and being arranged for reciprocating movement in the cylinder (14, 24) to vary the volume of the reaction chamber, and at least one crankshaft (13, 231, 232) mechanically coupled to the piston (11, 211, 212), wherein the mechanical coupling is configured such that, in use, rotation of the crankshaft (13, 231, 232) drives reciprocating movement of the piston (11, 211, 212) in a direction decreasing the volume of the reaction chamber to compress the reactants, and such that exothermic methanation in the cylinder (14, 24) causes an increase in pressure and expansion of gases in the reaction chamber which drives the piston (11, 211, 212) in a direction increasing the volume of the reaction chamber and thereby drives rotation of the crankshaft (13, 231, 232) so as to convert heat released by the methanation reaction into mechanical energy.
