Diffusion-dependent upgrading of hydrocarbons synthesized by Co/zeolite bifunctional Fischer–Tropsch catalysts

Insights into the mechanism of carbon chain growth on zeolite-based Fischer–Tropsch Co/Y catalysts

“…This was the same as the path reported in the literature. 47,48 According to the reaction energy barriers and reaction heat of R4, R5, and R6, it can be seen that the reaction energy barrier of R5 was 1.05 eV, lower than that of R4. Therefore, the optimal reaction path of H-assisted in the CO dissociation process was: CO hydrogenated to HCO first, then hydrogenated to H 2 CO, and finally H 2 CO dissociated to the CH 2 species (R1 -R5 -R6 path).…”

The Influence of Platinum on the Catalytic Properties of Bifunctional Cobalt Catalysts for the Synthesis of Hydrocarbons from CO and H2

“…The implementation of such technologies involves the creation of multifunctional catalytic systems that are effective in the conditions of FT synthesis and that have potential in the reactions of hydrocracking, isomerization, oligomerization, aromatization and hydrogenation of hydrocarbons [7][8][9][10][11][12][13][14][15][16]. The catalyst simultaneously implements the function of FT synthesis (hydrogenating metals) and hydrorefining products (zeolites or zeolitelike structures).…”
