3041. ----- [RUHRCHEMIE, A. G.]  [Process for Obtaining Pure Gasol From Gas Mixtures Containing It.]  German Patent Appl. R 111,138, R 595, file Oct. 1, 1941 (Cl. IV b-26 d).   TOM Reel 177, frames 1,677-1,683; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 1, chap. 48, 1948, p. 116.

In an improved method for obtaining pure gasol from mixtures containing it, such as the end gases of gasoline synthesis, a CO2-free product is obtained by first treating the gas mixture with a washing agent for the CO2 such as solutions of alkylolamines or of alkali carbonates and then completing the gasol extraction in the usual manner by a 2-stage pressure condensation.
