Influence of the Promoter Deposition Conditions on the Catalytic Properties of Ruthenium–Cobalt Systems in the Fischer–Tropsch Synthesis

The composition, structure, catalytic activity, and selectivity of alumina-supported cobalt catalysts promoted with ruthenium deposited by different methods were studied. The systems with bimetallic RuCo nanoparticles were studied in the Fischer–Tropsch synthesis. The catalyst containing 13.38 wt %...

Description
Summary:The composition, structure, catalytic activity, and selectivity of alumina-supported cobalt catalysts promoted with ruthenium deposited by different methods were studied. The systems with bimetallic RuCo nanoparticles were studied in the Fischer–Tropsch synthesis. The catalyst containing 13.38 wt % Co and 0.11 wt % Ru, prepared by microwave-assisted promoter deposition, exhibits higher selectivity with respect to liquid products (yield of С 5+ hydrocarbons 82.1%) and higher chain growth factor (α = 0.863) compared to the systems of similar composition (13.51 wt % Co, 0.13 wt % Ru), prepared using ultrasonic treatment. Microwave irradiation leads to the homogeneous distribution of bimetallic particles on the inner and outer surfaces of support pores, which results in increased yield of high-molecular-mass products in the Fischer–Tropsch process.
