Study of CO hydrogenation reaction on cobalt titania catalyst

Co hydrogenation on the cobalt catalyst with titania support (co/tio 2) without reduction condition and with a fixed-bed differential cylindrical reactor was kinetically studied. internal and external mass transfer resistances of the porous catalyst are low and neglected in experimentations. models have been developed using langmuir-hinshelwood-hougen-watson (lhhw) theory based on carbide and enolic mechanisms. models have compared with experimental data according to levenberg-marquardt algorithm. the best model (-rco = kph2/(1 + apco)2 ) is selected because of good agreement with experimental data. absorption step and hydrogen dissociation on surface of the catalyst is considered as a rate determination,simultaneously. activation energy and enthalpy of the carbon monoxide consumption were obtained 82.3 kj/mol and the 57.9 kj/mol,respectively.
