The Optimally Performing Fischer-Tropsch Catalyst

The optimally performing Fischer-Tropsch catalyst.

Microkinetics simulations are presented based on DFT-determined elementary reaction steps of the Fischer-Tropsch (FT) reaction. The formation of long-chain hydrocarbons occurs on stepped Ru surfaces with CH as the inserting monomer, whereas planar Ru only produces methane because of slow CO activation. By varying the metal-carbon and metal-oxygen interaction energy, three reactivity regimes are...

Aqueous-phase Fischer-Tropsch synthesis with a ruthenium nanocluster catalyst.

Introduction Hydrogenation of carbon monoxide to produce hydrocarbons, normally called Fischer-Tropsch synthesis (F-T synthesis), is one of the most important hydrogenation reactions due to its potential for the intermediate production of hydrocarbon fuels in the “postpetroleum” era. The reaction is favored at low-temperature and therefore reducing the particle size of the catalyst to several n...

Fischer–Tropsch synthesis on a model Co/SiO2 catalyst

A model Co/SiO2 catalyst was prepared by depositing cobalt on silica films in ultrahigh vacuum conditions. Fischer–Tropsch synthesis was carried out at a total pressure of carbon monoxide and hydrogen between 0.33 and 1.0 bar. The effects of reaction temperature and pressure on kinetics and chain growth probability were investigated. The turnover frequency, activation energy, and product distri...

Separation of Fischer-Tropsch Wax from Catalyst by Supercritical Extraction

Fischer-Tropsch Synthesis The CAER Perspective

The discovery of the catalytic synthesis of ammonia must rank as one of the important discoveries by mankind. In addition to providing the fertilizer needed to feed an expanding population, Fritz Haber’s recognition of recycle processing combined with the developing German technology to handle high pressures of hydrogen, led a major revolution in the chemical industry. In rapid succession, the ...
