The method is applicable to catalytic conversion of natural gas for production of synthetic fuels and other chemical products. It includes a phase of converting natural gas into a mixture of carbon monoxide and hydrogen (synthesis gas) and a phase of catalytic conversion of synthesis gas into motor fuels. First phase takes place at 800 - 900°C and 0.1 - 1 MPa in the presence of sorbent-catalyst, preliminarily saturated with oxygen as a result of its treatment with oxygen-containing gas. The sorbent-catalyst is based on aluminium oxides and mixed oxides, including oxides of nickel, cerium, zirconium and iron, with the following composition in mass percentage: mixed oxide - no more than 20 mass %; aluminium oxide - remaining part. The sorbent-catalyst is in granules form with surface-to-weight ratio 100 - 200 m/g. Regeneration of the sorbent-catalyst is performed at 500 - 600°C in a gas flow containing 1 - 5 volume % of oxygen, up to its saturation with oxygen. |
