Photocatalytic purification of volatile organic compounds in indoor air: A literature review

Although both the academic and the trade literature have widely acknowledged the need to foster the development of more-innovative products, little empirical research has examined the cognitive processes underlying the creation of these novel product concepts. In this research, three empirical studies examine how analogical thinking influences the idea-generation stage of the new product development process. The first study uses the verbal protocols of real-world industrial designers to trace the role of analogy in the context of a new product development task, and the second and third studies use an experimental approach to assess the effectiveness of different ideation strategies and conditions. Findings from these studies indicate that the originality of the resulting product design is influenced by the extent of analogical transfer, the type of analogies used, and the presence of external primes. In addition, these studies reveal a positive relationship between the originality of the product ...

The Influence and Value of Analogical Thinking During New Product Ideation

The subject of this report is chemistry and engineering for the application of heterogeneous photocatalysts. The state of the art in catalysts are forms of titanium dioxide or modifications thereof, but work on other heterogeneous catalysts is included.

Dimensionless analysis of slurry photocatalytic reactors using two-flux and six-flux radiation absorption–scattering models

One of the remaining challenges in application of heterogeneous photocatalysis for treatment of air streams containing dilute VOCs is to design a cost-effective photocatalytic reactor that simultaneously allows efficient contact of the contaminated air and solid catalyst while uniformly irradiating the solid catalyst with light. A pseudohomogeneous model was developed to study effects of system parameters on process performance for a gas–solid lamp-in-tube annular-photocatalytic-oxidation (PCO) reactor in which the annular space is filled with photocatalyst-coated packing. In this model the flow field is assumed to be uniform and radial diffusion negligible. Homogeneous reactions are neglected. Heterogeneous reaction rates follow Langmuir–Hinshelwood–Houghen–Watson kinetics with rate parameters extracted from independent experiments. A 1:D “two-flux” incidence submodel is used to account for the radial UV light distribution throughout the reactor annular space. This submodel requires knowledge of the UV lamp radiant emittance, the optical characterstics of the catalytic thin-film coating, and the UV irradiance at the outer wall of the reactor and contains only a single adjustable parameter—the mean free path between photon–catalyst interactions. The model was validated with experimental performance measurements for destruction of acetone and isopropyl alcohol in a bench-scale photoreactor. The validated model can be used to predict the optimum catalyst film thickness for given reactor dimensions, packing shape and size, and VOC abatement problem.
