Abstract in another language

Combining Fischer-Tropsch synthesis (FTS) and subsequent cracking of unwanted long-chain primary FT products in a tandem process is a successful procedure to improve the selectivity towards liquefied petroleum gas (LPG). To simplify the process, both reactions are carried out consecutively without prior product separation after FTS. In this work, the gas composition after FTS is imitated and, thus, the influence of unreacted CO and the by-product water on the hydrocracking of n-hexadecane as model substance is investigated. Furthermore, the reaction of alcohols and LPG components on a bifunctional Pt/H-ZSM-5 zeolite was examined as they are typically found in FT products. The cracking is affected negatively by the presence of CO, which is why a product separation upstream of hydrocracking after FTS can be considered as useful.
