Green Car Congress | New process produces high-octane synthetic fuel from low-octane Fischer-Tropsch gasoline
In recent years, interest in the Fischer-Tropsch synthesis has increased significantly and thus it makes possible to produce synthetic motor fuels by using alternative energy resources as raw materials such as natural gas, coal, and biomass. The resulting product, which is commonly called synthetic crude oil, is a mixture of light and medium distillates with a boiling point of up to 350–360 °C. To obtain commercial gasoline from synthetic crude oil requires costly and multi-stage refining in the processes of hydrogenation, isomerization and reforming, which greatly complicates the entire chain of production of commercial gasoline. In addition, the industrial technology of upgrading the Fischer-Tropsch gasoline fraction (reducing the amount of olefinic hydrocarbons, as well as increasing detonation resistance) is a multistage process that exceeds the processing of straight-run gasoline obtained from petroleum feedstock in the number of stages.
In this regard, a significant resource base is unclaimed for economic reasons. The development of a fundamentally new technology for upgrading gasoline Fischer-Tropsch will ensure energy security and diversification of raw materials for the production of motor gasoline.
