Effect of Cobalt Catalyst Confinement in Carbon Nanotubes Support on Fischer-Tropsch Synthesis Performance

Pre-treating the multi-walled carbon nanotubes (CNTs) support by refluxing in 35 volume% nitric corrosive followed by warming at the
temperature of 600°C to 900 °C and results in the development of imperfections on the carbon nano tubes. Expanding in the temperature of the
pre-treatment of the carbon nanotubes from 600 °C to 900 °C, upgraded the part of cobalt-oxide nanoparticles exemplified in the channels of
carbon nanotubes from 31% to 70%. The demonstration of cobalt just as carbon nanotubes in fischer-tropsch blend (FTS) was assessed in a fixedbed
small scale reactor at a temperature of 240 °C and a weight of 2.0 MPa. The most noteworthy cobalt change got over Co/CNTs.A.900 was
59% and it dropped by ~3% following 130 hour of time-on-stream. In any case, greatest cobalt change utilizing Co/CNTs.A.600 impetuses was 28%
and it will be diminished quickly by about 54% following 130 hours of time-on-stream. This discovery shows that the joined corrosive and warm
pre-treatment of carbon nanotubes support at 900 °C and furthermore it improves the strength and movement of the Co/CNTs impetus in FTS.
