Fischer–Tropsch synthesis on a model Co/SiO2 catalyst
A model Co/SiO2 catalyst was prepared by depositing cobalt on silica films in ultrahigh vacuum conditions. Fischer–Tropsch synthesis was carried out at a total pressure of carbon monoxide and hydrogen between 0.33 and 1.0 bar. The effects of reaction temperature and pressure on kinetics and chain growth probability were investigated. The turnover frequency, activation energy, and product distri...
متن کاملReactions of Olefins Added during Fischer-Tropsch Synthesis over Supported Cobalt Catalyst
The control on product distributions in Fischer-Tropsch synthesis by feeding olefins in the n-paraffin solvent over a 20 wt.% Co/SiO2 catalyst under the typical reaction conditions of 503K, 2.1MPa, H2/CO = 2, and co-fed olefins 16 mol% in CO base in a trickle bed reactor has been studied. The selected co-fed olefins include 1-octene, 2-octene and 1-dodecene. Results showed that the addition of ...
متن کاملThe Effect of Temperature on Product Distribution over Fe-Cu-K Catalyst in Fischer-Tropsch Synthesis
The iron-based catalyst was prepared by a microemulsion method. The composition of the final nanosized iron catalyst, in terms of the atomic ratio, contains 100Fe/4Cu/2K. The experimental techniques of XRD, BET, TEM, and TPR were used to study the phase, structure, and morphology of the catalyst. Fischer-Tropsch synthesis (FTS) reaction test was performed in a fixed bed reactor under pressure o...
متن کاملKinetic Study of Fischer Tropsch Synthesis over co Precipitated Iron-Cerium Catalyst
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...
