In the case of the falling film micro-photo reactor the catalysis in the form of gas-liquid is hence studied and there are reaction plates with he required microchannel in order to support it. There is an interfacial area here to the size of 20,000 m2/m3. This is necessary to ensure the reactant gas will move over the film and flow as a liquid. Different forms of micro-photo reactors will have different form of advantages. The advantages of using micro-photo reactor in the context of issues with batch system were first identified by researchers Porter and Volman. Some of the benefits cited in research were that the thin layers ensured there was better penetration. This was not the case in the batch systems. There is also a surface rea that support better mixing and hence efficient heat and mass transfer would be achieved. In such cases where the starting reagents might need to be mixed in a way such that the reaction speeds up, the batch processes faced issues (Coyle, & Oelgemöller, 2008). On the other hand, in the use of a micro-photo reactor, the irradiation time will be very much reduced and hence the flow rates can be controlled. Overall efficiency increased. Some of the other advantages that come with the use of micro-photo reactor are that in the catalyst applications testing they would be useful for eliminating the waste and improving reusability of the catalysis. They are much safer in the context of automation too and this was also an issue in batch processes. Furthermore, there are reactions that can be controlled better because they are specifically targeted to be initiated in small volumes only. So in the context of testing, it is therefore much easier than that of the batch reactors (Griesback et al, 2012). The processes can be controlled with respect to pressure and then tested and then with temperature or the residence time in the case of research. At the micro level element, the most important significance of using the micro-photo reactor over any other is that of the security of the actions. Exothermic reaction resulting in explosions is reduced. In the case of clustered reaction, these micro-photo reactors are useful for understanding optimization effects and more.
There are different forms of photochemical reactions hence used in the micro-photo reactor. Based on the basic categories, these are divided into the homogeneous reactions where the reagents are usually in one state or they might be heterogeneous reaction and then there are catalytic reactions where the heterogenic catalysis is the investigation carried out (Chang et al, 2008). This literature review paper concerns itself with understanding the catalytic reactions only. Under homogeneous reactions, some of the observed chemical reactions are that of photopinacolization where the transformation of benzopehnone is studied. Here the isopropanol solvent is used. The Barton reaction is yet another reaction where a steroidal substance reactor testing would be done. Photocyclo-addiiton reactions are also a form of homogeneous reaction. Heterogeneous reactions on the other hand are those reactions where liquid and gas reagents are involved and the falling film type reactor micro-photo reactor was specifically constructed for this prose. The form of reactions that are involved here are that of the photo oxygenation reactions, the photochloriantion reactions and more. Although these studies also might be used in the understanding of some form of catalysis, these are not part of the primary investigation being carried out in this research.
