Abstract

A catalytic setup for Fischer-Tropsch synthesis to alkanes and alcohols is described. Within this single-channel reactor unit the reaction conditions can be varied in the ranges of 25 – 400 °C, 1 – 100 bar, and 300 – 120 000 h–1 gas hourly space velocity (GHSV). The broad product spectrum is efficiently analyzed by GC/MS. The concept of effective carbon numbers, as typically applied in refining and high-molecular chemistry, is suitable for the product spectrum comprising mainly alkanes, alkenes, alcohols, aldehydes, and carboxylic acids. This article provides details about the setup and general measurement procedures.
