Abstract:
Desulphurised natural gas is mixed with steam to give a required steam to
carbon molar ratio of 3 is steam-reformed. eaction is endothermic and
takes place with a catalyst at 850-g000e and 25 bar. Reaction scheme is:
After cooling, gas is passed through a pressure swing adsorption (PSA) unit
which operates cyclically on a adsorption, depressurisation, purging,
pressurisation cycle. Typical efficiencies are 75 percent.
