Reaction modeling on the phosphorous-treated Ru/Co/Zr/SiO2 Fischer–Tropsch catalyst with the estimation of kinetic parameters and hydrocarbon distribution

A Single-Event MicroKinetic model for the cobalt catalyzed Fischer-Tropsch Synthesis

“…An increasing H2 to CO molar inlet ratio increases the CO conversion as has been found by other experimental studies [20]. At the investigated operating conditions, there is no pronounced effect of the H2 to CO molar inlet ratio on the alkanes and alkenes selectivities at isoconversion conditions for the Co/CNT catalyst.…”

“…There is a general consensus that the reaction proceeds through a polymerization-like scheme where the monomeric building block is formed on the catalyst surface and is inserted in a growing chain [1]. This has led to the development of various microkinetic models for Co catalyzed FTS [15][16][17][18][19][20][21][22][23][24][25][26]. Klinke et al [16] developed a microkinetic model based on direct CO dissociation and chain growth by inserting CHx species.…”

A Comprehensive Kinetic Model of Fischer-Tropsch Synthesis over Supported Cobalt Catalyst

“…The average error calculated on these data for total hydrocarbon, olefin and paraffin are 15.4, 27.5, 12.5%, respectively which are satisfactory and comparable to those of Visconti and Kwack [14,15], especially for parafiins, better results were observed. However, more investigation needs to be done for the model of olefin formation.…”

“…However, only few comprehensive models on the polymerization mechanism of the cobalt based Fischer-Tropsch reaction are described in literature [11][12][13]. The most important works on comprehensive kinetic model over cobalt catalyst have been done by Visconti [14], Fontenelle and Fernandes [11] and Kwack [15]. In these works, a single reaction rate has been assumed for initiation step and its entire reactions, which can be one of the weaknesses of these complete kinetic models.…”

Modelling of a fixed bed reactor for Fischer–Tropsch synthesis of simulated N 2 -rich syngas over Co/SiO 2 : Hydrocarbon production

“…Kwack et al depicted the performance of the catalytic FT catalyst over Ru/Co/Zr/SiO 2 . They also developed the kinetic mode along with the estimation of kinetic parameters to predict the effect of the operating conditions on HC distribution and CO conversion [23]. Rahmati et al [24] obtained an intrinsic rate for the FT synthesis with a tubular fixed bed reactor over a promoted Fe catalyst.…”
