The conversion of carbon monoxide with hydrogen was studied on a standard Os on SiO2 catalyst at different reaction temperatures, in the range between 200 and 300 °C. Additionally, supported di- and triatomic organometallic Os complexes were tested for their activity in the Fischer-Tropsch synthesis at 220 °C. All compounds showed formation of hydrocarbons, indicating that the organoosmium complexes are indeed active for C─C bond formation. Osmium as Fischer-Tropsch catalyst, however, is approximately 100 times less active compared to ruthenium. Very high methane selectivities (> 90 C-%) were obtained as well as high olefin to paraffin ratios, in particular with the organometallic complexes tested.

Fire And Explosion

Interest in Fischer-Tropsch technology is increasing rapidly. Alkyl/alkenyl products from Fischer-Tropsch synthesis are alternative, renewable, environmentally and economically attractive fuels and there are considered one of the most favorable fuels for conventional fossil-based fuels. The chemistry of this gas-to-liquid industry converts synthesis gas containing carbon monoxide and hydrogen to oxygenated hydrocarbons such as alcohols. The fire hazards associated with the use of these liquid hydrocarbons mixtures are obvious. This article aims to explore the fundamental fire and explosion characteristics for main products composition from Fischer-Tropsch synthesis.

Supported Iron

In silica supported iron Fischer–Tropsch catalysts, promotion with copper strongly enhances both hematite reduction and magnetite carbidisation, while potassium promotion hinders reduction of hematite to magnetite but enhances magnetite carbidisation in carbon monoxide.
