2810. -------- (Ruhrchemie, A. G.). [Catalytic Conversion of Carbon Monoxide Into Higher Hydrocarbons.] German Patent 701,846. Dec. 24, 1940 (Cl. 12 o-1.03). Chem. Abs., vol. 35, 1941, p. 8259.

In synthesizing higher hydrocarbons from CO and H₂ a nonvolatile product deposits on the catalysts. The deposit is periodically removed by passing H₂ or steam or a suitable solvent without lowering the temperature appreciably and without removing the catalysts.
