Molecular Views on Fischer–Tropsch Synthesis Chemical Reviews

The Fischer–Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons. WebAbstract Dissociation of CO on a Co(0001) surface is explored in the context of Fischer–Tropsch synthesis on cobalt catalysts. Experiments show that CO dissociation can occur on defect sites around 330 K, with an estimated barrier between 90 and 104 kJ mol − 1 . Despite the ease of CO dissociation on defect sites, extensive carbon … nottingham city council planning department
