WebNumerous chain growth mechanisms, namely CO insertion and carbide, and active sites (flat and stepped surfaces) have been proposed to explain how hydrocarbons are formed from syngas during the Fischer-Tropsch reaction on Ru catalysts, particularly active and selective toward long-chain products. WebA quantitative approach is used to understand the chain growth mechanism in FT synthesis on the Ru, Fe, Rh, and Re surfaces. The C−C coupling reactions are extensively calculated on the stepped met... Chain Growth Mechanism in …
