Abstract
The present invention relates to a method of manufacturing a gas rich in methane by subjecting two varieties or more of hydrocarbons having more than 2 carbon atoms per molecule and different mean molecular weights to steam-reforming process comprising at least two stages, wherein a mixture consisting of hydrocarbons whose means molecular weight is relatively small and steam is introduced to the nickel-containing catalyst bed for the first stage at a temperature in the range of 350.degree. to 550.degree.C, and subsequently, the resulting product is mixed with hydrocarbons whose mean molecular weight is larger than that of the preceding hydrocarbon -- along with steam, if necessary -- and is introduced to the nickel-containing catalyst bed at a temperature in the range of 300.degree. to 550.degree.C for the second stage.
