Abstract

Fischer-Tropsch synthesis in supercritical phase was developed and its reactional behavior and mass transfer phenomenon were analyzed by both experimental and simulation methods. The same reaction apparatus and catalysts were used for both gas-phase reaction and liquid-phase F-T reactions to correctly compare characteristic features of diffusion dynamics and the reaction itself, in various reaction phases. Efficient transportation of reactants and products to the inside of catalyst bed and pellet, quick heat transfer and in situ wax extraction from catalyst by supercritical fluid were accomplished and deactivation of the catalyst was suppressed. As an application of this process, wax can be produced effectively in the supercritical phase reaction, especially in the case when heavy olefin is added to the supercritical fluid.
