Abstract: The Catalytic Rich Gas process (CRG) was developed by the British Gas Corporation in the 1960s tor the manufacture of town gas from light naphtha, following earlier work on (a) methane synthesis or methanation from oxides of carbon and hydrogen available by the gasification of coal and (b) the gasification of coal and (b) the gasification of methanol to produce gas suitable for use as town gas or SNG. In the original CRG process the oil feedstock was vaprorised mixed with a gas containing hydrogen and desulphurised over a nickel molybdenum catalyst followed by zinc oxide or Luxmasse, steam was then added and the feedback gasified adiabatically at elevated pressure over a nickel based catalyst to give a gas of approximately 650 Btu/ft3. This gas was then blended with a lean gas from a high temperature reforming stage (approximately 350 Btu/ft3) to obtain a product after partial carbon dioxide removal with a calorific value of 500 Btu/ft3.
