Influence of the geometry of a monolithic support on the efficiency of photocatalyst for air cleaning

Design of a micro-channel reactor for decomposition of organic pollutants in waste water treatment

“…The integration of Eq. (5) is possible only when there is no limitation by mass transfer, no difference of concentration between bulk flow and the catalyst surface (Furman et al, 2007, Dingwang et al, 2001. By integrating equation (5) between the reactor inlet and outlet, it follows:…”

Microstructured Reactors Designed by Stereolithography and Characterized by Fluorescent Probes

“…Stereolithography process was used to polymerize photoresist at the surface of the slide (Figure 1). This technology enables the fabrication of many complex shapes and has been presented in previous papers [6]. The Spectra-Physics Model 2020 argon ion laser was used for irradiations in the near ultraviolet (wavelength 363.8 nm) with an exposure of 300 mJ/cm 2 .…”

UV-A photocatalytic treatment of Legionella pneumophila bacteria contaminated airflows through three-dimensional solid foam structured photocatalytic reactors

“…Recently, Zahraa and co-workers studied the influence of the geometry of a monolith support on the efficiency of photocatalysts for air cleaning, by designing Nd-YAG laser assisted stereolithography-shaped epoxy resins as 3D supports for TiO 2 layers, and further by investigating the static mixer, the crossed channels and the star geometry configurations using methanol as model VOC [12]. They developed a model that described the basic phenomena involved, such as light absorption, hydrodynamic and transfer processes and also reaction kinetics.…”
