Continuous Flow Hydroxylation of Benzene to Phenol in a …
2024年9月3日 · In this work, we successfully developed a flat-plate reactor for continuous flow photocatalytic hydroxylation of benzene to phenol. The main conclusions are as follows: (1) The smectite clay, with high transparency and low light scattering, and the casting template were keys to the uniform immobilization of P25 over the glass surface.
Continuous photocatalytic reactor: Critical review on the design …
2022年6月1日 · Flat plate reactor is a laminar flow reactor, where the degradation efficacy falls owing to limited solar radiation penetration at greater flow rates. Nevertheless, it produces better results for slurry-type reactors over the immobilized types.
Flat-plate mesophotoreactor with a serpentine channel and …
2024年10月29日 · As the grid count increases, there is a continuous decrease in pressure drop. And when the number of grids increases from 4 to 5, the pressure drop remains unchanged. ... Based on the above results, several principles that should be followed when scaling up flat-plate photochemical reactors were summarized as follows: 1. ensure good mixing and ...
What are the basic elements of an electrochemical reaction? How do we leverage electrochemistry to produce chemicals in continuous flow reactors? Why are we interested in E-chem synthesis? What are components of E-chem rxn? *Assume perfect mixing (rAthe same everywhere) *Assume steady state (no accum.)
Photocatalytic Reactor Modeling: Application to Advanced Oxidation ...
2019年8月23日 · Vaiano et al. modeled a flat-plate continuous reactor with N-doped TiO 2 immobilized on glass spheres. They developed a reactor model considering plug flow behavior inside the packed bed, without considering external mass transfer phenomena.
Development of intensified flat-plate packed-bed solar reactors …
2021年1月7日 · In this work, we present a rationale for the design of heterogeneous photoreactors, which is applied for the fabrication of a flat-plate packed-bed reactor. We do this by exploring (i) the configuration of the flow distributing region and (ii) the technology used for prototyping the selected designs.
