| Photocatalytic conversion of CO2 into valuable products has attracted many scientists and has developed as a promising technology. In the photo reaction, the photoreactor geometry has a significant effect on the reactor performance which depends on the photon collecting efficiency. This thesis work presents a new reactor design that converts CO2 and H2O to CO, H2, CH4 and C2H 6 in a continuous flow annular heterogeneous reactor. Experimental work was performed for designing the reactor, choosing a suitable light source and medium (support), and determining a suitable catalyst coating procedure.;The goal of the project was to design an annular photoreactor for CO 2 photoreduction with H2O over TiO2 and under UV light with optimal production rates and to serve as an enhancement to other common photoreactors.;This research seeks to benefit advanced photoreduction applications of continuous two-phase (solid-gas) systems. The new design has many advantages, including small reactor size relative to conversion, low light output, high surface area, and high light utilization which provide high production rates and more products such as CO, H2, CH4 and C2H 6. |
