Kinetic model of CO2 photocatalytic reduction over TiO2
Original language description
Kinetic of CO2 photocatalytic reduction by water vapour powder was examined in a stirred batch annular reactor with a suspended TiO2 catalyst at 110 kPa. An 8 W Hg lamp with a peak light intensity at 254 nm was used for illumination (0-24 hour). Two mainproducts were determined: methane in gas phase and methanol in liquid phase. Hydrogen and low amounts of carbon oxide were also detected. Kinetic data were evaluated by non-linear regression method and plausible mechanism was proposed. First of all carbon monoxide is formed, from which both methane and methanol is formed in the parallel reactions. The products, CO and O2, were adsorbed and photo-oxidized in a reverse reaction since they especially CO, were not effectively desorbed and diffused from thecatalyst surface. The comparison of experimental CH4 and CH3OH yields and yields determined according kinetic model was made.
