2711. POTTS, H. E. Conversion of Carbon Monoxide Into Hydrocarbons. British Patent 526,465, Sept. 18, 1940. Chem. Abs., vol. 35, 1941, p. 7156.

Ratio of 2 parts or less of H₂ to 1 part of CO is employed and when the activity of the catalyst has decreased below a certain degree, the catalyst may be reactivated with a gas containing at least 2.5 parts of H₂:1 part of CO. The reactivated catalyst may be even more active than the original catalyst. It is advantageous to work in 2 or more reaction vessels in order to switch over for the activation. Known catalysts can be used.
