Mechanism of Hydrocarbon Synthesis over Fischer-Tropsch Catalysts

Production of 11C-labelled n-hexane for use in positron emission imaging

“…The formation of C~ surface species from CO at high temperature is generally believed to take place via the Boudouard reaction [11,14]. This is confirmed from our experiments where the production of 11CO2 has been observed during high temperature adsorption of 11CO.…”

Recent Progresses in Understanding of Co-Based Fischer–Tropsch Catalysis by Means of Transient Kinetic Studies and Theoretical Analysis

“…Fortunately, these issues have been tackled with by some correction methods such as the site-dependent correction factors [125,129], which can provide an adsorption energy in the range of 1.10-1.40 eV and the current methods will be used in future, especially for high CO coverage. It is clearly seen that the chemisorption energies of most C1 species are around or more than 1 eV except for CH 3 OH, which binds weakly through the O atom since there is no unsaturated atoms in CH 3 OH [120]. Interestingly, the adsorption energies of n-alkyl with chain length n from 2 to 6 are almost the same because the bonding of these species with the surface is similar.…”

“…Fischer-Tropsch synthesis (FTS) is an alternative process for producing transportation fuels and chemicals by converting syngas derived from natural gas, biomass and coal [1][2][3][4]. Recently, the increase in demand for transportation fuels and the large reserves of natural gas have made FTS an attractive industrial process.…”

Oxidation of carbidic carbon on a rhodium surface

“…Rhodium is a good catalyst for the synthesis of hydrocarbons and oxygenated compounds [1,2], and is also one of the main components of the catalyst for automobile exhaust gas cleaning [3].…”
