ABSTRACT:
Natural gas of low heating value, high CO.sub.2 content, is converted to valuable products by the combination process of steam reforming the desulfurized gas, subjecting the effluent of the steam reformer to a water gas shift reaction and converting the resultant carbon dioxide, the unreacted carbon monoxide and hydrogen to liquid product useful as fuel, e.g. methanol. In a preferred embodiment, the gas phase separated from the liquid fuel products is processed to provide a gas sufficiently rich in carbon dioxide for use in tertiary recovery of petroleum from natural reservoirs which have produced the quantity of oil available by natural drive.
