Fischer-tropsch reaction
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 … See more The Fischer–Tropsch process involves a series of chemical reactions that produce a variety of hydrocarbons, ideally having the formula (CnH2n+2). The more useful reactions produce alkanes as follows: (2n + 1) H2 + n CO … See more Four metals are active as catalysts for the Fischer–Tropsch process: iron, cobalt, nickel, and ruthenium.Since FT process typically transforms inexpensive precursors into … See more Ras Laffan, Qatar The LTFT facility Pearl GTL at Ras Laffan, Qatar, is the second largest FT plant in the world after Sasol's … See more Using conventional FT technology the process ranges in carbon efficiency from 25 to 50 percent and a thermal efficiency of about 50% for CTL facilities idealised at 60% with GTL facilities at about 60% efficiency idealised to 80% efficiency. See more Fischer–Tropsch plants associated with coal or related solid feedstocks (sources of carbon) must first convert the solid fuel into gases. These gases include CO, H2, and alkanes. This conversion is called gasification. Synthesis gas ("syngas") is obtained from coal … See more The F-T process attracted attention as a means of Nazi Germany to produce liquid hydrocarbons.
