Methane steam reforming catalyst
WebMethane steam reforming involves five species in two reversible reactions: CH 4 + H 2 O CO + 3H 2 DH 25ºC = 206 kJ/mol (1) CO + H 2 O CO 2 + H 2 DH 25ºC = – 41 kJ/mol (2) The reforming reaction (1) is favoured thermodynamically by high temperature and low pressure, while reaction (2), i.e. the water– gas shift (WGS) reaction, does not ...
