Zr-pillared montmoril lonite supported cobalt nanoparticles for Fischer – Tropsch synthesis

In this article Fischer–Tropsch(FT) synthesis was studied over cobalt nanoparticles supported on modifed Montmorillonite(Zr-PILC).Co-loaded/Zr-PILC catalysts were synthesized by hydrothermal methods and were characterized by XRD,XRF,BET,H2-TPR,TGA and SEM techniques.FT reactions were carried out in fxed bed microreactor(T 225 1C,260 1C and 275 1C,P 1,5 and 10 bars).The FT-products obtained over Co-loaded/Zr-PILC catalysts showed increased selectivity of C2–C12hydrocarbons and decreased selectivity towards CH4and higher molecular weight hydrocarbons(C21) at a TOS of 2–30 h as compared to the Co-loaded/NaMMT catalysts.With increase in reaction temperature from225 1C to 275 1C,CO-conversion and CH4selectivity increases while that of C5+hydrocarbons decreases.Decrease in CH4selectivity while increase in C5+hydrocarbons and CO-conversion were observed on increasing the pressure of reaction.

Zr-pillared montmorillonite supported cobalt nanoparticles for Fischer–Tropsch synthesis

In this article Fischer–Tropsch (FT) synthesis was studied over cobalt nanoparticles supported on modified Montmorillonite (Zr-PILC). Co-loaded/Zr-PILC catalysts were synthesized by hydrothermal methods and were characterized by XRD, XRF, BET, H₂-TPR, TGA and SEM techniques. FT reactions were carried out in fixed bed microreactor (T=225 °C, 260 °C and 275 °C, P=1, 5 and 10 bars). The FT-products obtained over Co-loaded/Zr-PILC catalysts showed increased selectivity of C₂–C₁₂ hydrocarbons and decreased selectivity towards CH₄ and higher molecular weight hydrocarbons (C₂₁) at a TOS of 2–30 h as compared to the Co-loaded/NaMMT catalysts. With increase in reaction temperature from 225 °C to 275 °C, CO-conversion and CH₄ selectivity increases while that of C₅₊ hydrocarbons decreases. Decrease in CH₄ selectivity while increase in C₅₊ hydrocarbons and CO-conversion were observed on increasing the pressure of reaction.
