ONLINE SINGLE RUN ANALYSIS OF EFFLUENTS FROM A FISCHER-TROPSCH REACTOR

A simple and inexpensive gas chromatographic (GC) analysis system was developed for the on-line and automatic determination of most of the components in the effluent from a Fischer-Tropsch synthesis catalytic reactor. A total of 120 specific compounds were separated, including C//1-C//1//2 paraffins and olefins, alkyl aromatics and C//1-C//4 alcohols. Argon was used as internal standard, allowing accurate mass balances to be made of the carbon entering and leaving the reactor. The system consists of a single GC oven, a 6- and 10-port sampling valve, a packed and a capillary WCOT column, a TC detector and an FID.
