Kinetic modeling of lignin catalytic hydroconversion in a semi-batch reactor

Résumé

A kinetic modeling for lignin catalytic hydroconversion over a supported CoMoS catalyst in a semi-batch reactor has been constructed based on analysis results from Gel Permeation Chromatography (GPC) and two-dimensional Gas Chromatography (GC × GC). The model includes 15 pseudo-component lumped products classified by their states and functional groups. Hydrogen consumption, liquid-gas mass transfer resistance and vapor-liquid equilibrium are accounted for. Physical and chemical parameters were estimated from experiments carried out at 350 °C and 80 bar. The resulting model is able to fit the experimental data well. From estimated parameters, it is deduced that the bottlenecks of lignin catalytic hydroconversion are the deeper conversion of the soluble oligomeric fractions and the relatively slow hydrodeoxygenation rate.
