Novel bimetallic 1%M-Fe/Al2O3-Cr2O3 (2:1) (M = Ru, Au, Pt, Pd) catalysts for Fischer-Tropsch synthesis

The main objective of this work was to study the physicochemical and catalytic properties bimetallic supported catalysts [1%M-Fe/Al2O3-Cr2O3 (2:1) (M = Ru, Au, Pt, Pd)] in Fischer-Tropsch synthesis. Furthermore, investigated effect noble metal addition iron-supported on their reactivity. were studied using a range characterization techniques such as X-ray diffraction (XRD), temperature-programmed reduction (TPR-H2), desorption ammonia (TPD-NH3) BET (Brunauer – Emmett - Teller method). activity tests performed by synthesis high-pressure fixed-bed reactor gas mixture H2 CO with molar ratio 1:1. correlation between performance hydrogenation also investigated. reactivity results showed that most active system exhibited high specific surface area, highest total acidity reducible catalyst compared other tested. In addition, AuFe selectivity towards liquid product formation during hydrogenation.
