Process for Treating Synthesis Product. United States Patent 2,653,960, Sept. 29, 1953; appl. filed Mar. 26, 1949, Serial No. 83,732; 7 claims (Cl. 260-450). Claim 1. A process for treating a product containing H2O, hydrocarbons and O2-containing organic compounds, comprising alcohols, esters, acids, aldehydes, and ketones and which is obtained by the catalytic conversion of CO and H2 into synthetic fuel, which comprises separating the synthesis product obtained by catalytic conversion of synthesis gas into a gas phase and a liquid phase comprising oil and H2O phases; contacting said entire liquid phase in the vapor state at a temperature of 500°-1,000° F. with a solid basic material selected from the group consisting of alkali metal compounds, alkaline earth compounds, and mixtures thereof, whereby esters are hydrolyzed to alcohols and acids and acids are decarboxylated to hydrocarbons and ketones; cooling said base-treated liquid phase; separating said base-treated liquid phase into an oil fraction and a H2O fraction; vaporizing said oil fraction containing oxygenates mainly in the form of alcohols and ketones; contacting said oil fraction with a particulate adsorbent at a temperature of 400°-700° F., wherby said O2-containing organic compounds mainly alcohols and ketones, are adsorbed on said adsorbent; separating said adsorbent containing O2-containing organic compounds adsorbed thereon from said vaporized oil fraction; and recovering O2-containing organic compounds comprising mainly alcohols and ketones from said separated adsorbent. |
