A challenge to the simulation of Fischer–Tropsch reaction system is lack reliable kinetic models which correctly account for deviations from ideal polymerisation behaviour. The current trend in literature attribute these effects only. This ignores that reactions synthesis contain many aspects an equilibrium-controlled process. arises since rate chain growth much faster than monomer formation CO...

The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...

In this study, the effect of preparation technique of carbon nanotube (CNT)-supported cobalt catalysts on the activity and selectivity of Fischer-Tropsch synthesis (FTS) was studied. Different concentrations of acetic acid were used for the pretreatment of the catalyst support to modify the surface properties of CNT. This modification improved the reduction degree and dispersion of supported co...

Nano-structure of Co–Mn spinel oxide was prepared by thermal decomposition method using [Co(NH3)4CO3]MnO4 as the precursor. The properties of the synthesized material were characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET), Transmission Electron Microscopy (TEM), surface area measurements, Energy-Dispersive X-ray (EDX) spectroscopy analys...

Polymeric carbon was deposited over Siralox supported cobalt catalysts by an ethylene treatment at 230 °C and 260 °C. Cobalt with particle sizes of 10 14 nm were studied. Temperature programmed hydrogenation Raman spectroscopy analyses the species found to be similar those formed during Fischer-Tropsch synthesis. The tested in high-throughput 16 parallel reactors 20 bars 220 °C, using a H2/CO r...

Synthetic fuels play an important role in the defossilization of future aviation transport. To reduce ecological impact remote airports due to long-range transportation kerosene, decentralized on-site production synthetic paraffinic kerosene is applicable, preferably as a near-drop-in fuel or, alternatively, blend. One possible solution for such power-to-liquid process. We describe basic develo...
