Composite pelletized catalyst for higher one-pass conversion and productivity in Fischer–Tropsch process

Preparation of Raney cobalt and identification of surface structures responsible for catalytic activity in the Fischer–Tropsch process

“…In general, the thermal conductivity of a particular system is determined both by its chemical composition, phase composition, and the structure of the porous body, the thermal resistance of contact barriers, and the nature of the gas mixture or liquid that contacts it and fills the pores. The use of both individual porous metals formed into granules and composites with it makes it possible to create effective catalysts for the synthesis of C 5 –C 100 hydrocarbons from CO and H 2 by mixing cobalt powders, aluminum metal, and binder with the liquid phase, extruding the resulting paste, and drying and calcining the obtained granules [31].…”

Fischer–Tropsch synthesis on cobalt-based catalysts with different thermally conductive additives

“…calculated on support weight and was confirmed by elemental analysis for each catalyst. The catalysts investigated in this paper were prepared according to the techniques described in detail elsewhere [29,30].…”

“…Unfortunately we don't have technical capability to measure temperature profile in the investigated reactor. But we did some experiments at a scaled-up semi-industrial facility (which is not the subject of this manuscript but described in detail elsewhere [37]) to demonstrate the effect of thermal conductive component introduction. Thermal conductivity of the reference catalyst (which did not contain thermally conductive additive) was 0.25 W/(m·K) and the difference between the wall and centre temperature was about 12-16 °C.…”

CoZr nanocomposites in a ceramic–metal AlOx(OH)y/Al matrix with a different Co/Zr ratio and its potential for syngas processing

“…In a number of studies, attempts were made to obtain Co-catalysts with high thermal conductivity. [9][10][11][12][13][14] The porous structure of the catalyst is essential for efficient mass transfer. A number of studies are aimed at developing catalysts with an optimal porous structure.…”
