Special Issue Information

Dear Colleagues,

Continued progress in computing hardware and software are markedly affecting the approaches adopted to chemical processes equipment analysis and design. Particularly, Computational Fluid Dynamics (CFD) is becoming an increasingly used tool in many fields within Chemical Engineering.

Chemical reactors are one of the exemplifying cases of the sorts of equipment benefitted by the abovementioned progress, the design of which may be notably improved by the use of CFD. This is because this tool is capable of describing the hydrodynamics of very complex situations; for instance, as occurs in most of the multiphase reactors. Due to the dramatic effect of the fluids’ contact on reactor performance it is clear that CFD is to some extent revolutionizing chemical reaction engineering. Obviously, not only hydrodynamics is important. Heat transfer and chemical kinetics are integrated in CFD models in a natural way through the conservation equations. Therefore, CFD modeling allows a complete description of the phenomena governing reactor performance, thus, giving rise to an unprecedented powerful tool to guide design and scale-up.

Within this context, this Special Issue aims at compiling relevant contributions showing the capabilities of CFD applied to the analysis and design of any type of chemical reactor. Manuscripts in which the modeling results are validated by experimental evidence are particularly welcome.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ChemEngineering is an international peer-reviewed open access quarterly journal published by MDPI.

The present work deals with the kinetic analysis and modelling of glycerol (GLY) oxidation in the liquid phase over a supported gold catalyst. A Langmuir-Hinshelwood model was proposed, after considering the effect of the reaction temperature, the NaOH/GLY ratio and the initial concentrations of GLY and GLY-Product mixtures. The proposed model effectively predicted the experimental results, and both the global model and the individual parameters were statistically significant. The results revealed that the C–C cleavage to form glycolic and formic acids was the most important reaction without a catalyst. On the other hand, the supported Au catalyst promoted the GLY oxidation to glyceric acid and its further conversion to tartronic and oxalic acids. Regarding the adsorption terms, glyceric acid showed the highest constant value at 60 °C, whereas those of GLY and OH were also significant. Indeed, this adsorption role of OH seems to be the reason why the higher NaOH/GLY ratio did not lead to higher GLY conversion in the Au-catalysed reaction. Full article
