Special Issue Information

Dear Colleagues,

Appropriate design of catalytic and photocatalytic reactors is the key for process development. Different types of catalytic reactors were proposed to cope with the variety of applications, where heat and mass transfer, as well as pressure drop could limit the reaction in some way, due, e.g., to productivity, selectivity or safety issues. Therefore, in catalytic applications, the concepts of reactivity, kinetics, transport phenomena and reactor modelling are intimately in contact, in order to provide detailed sizing and the correct prevision of reactor performance. Conversely the applications span from super-giant plants (e.g. the case of ammonia synthesis), to catalytic and photocatalytic microreactors. Photocatalysis, on its side, extends somehow the complexity of catalytic reactors scale-up due to additional important effect of irradiation and the need of transparent windows/surfaces, which impose different design requirements. In this, it represents another frontier for process scale up, based on the spreading interest of photocatalysis for widely different applications. This special issue collects original research papers, reviews and commentaries focused on the challenges for reactor design and modelling, specifically applied to the development of catalytic and photocatalytic processes. Submissions are welcome especially (but not exclusively) in the following areas:

- Kinetics of catalytic and photocatalytic reactions

- Sizing and modelling of catalytic and photocatalytic reactors

- Transport phenomena in catalytic and photocatalytic processes

- Modelling flow in catalytic and photocatalytic reactors

- Computational Fluid Dynamics applied to catalytic and photocatalytic reactors.

- Process design and scale up issues

- Process simulation

- Innovative concepts of reactors and microreactors for catalytic and photocatalytic applications

Catalytic steam gasification of extra-heavy oil (EHO) fractions was studied using functionalized aluminosilicates, with NiO, MoO3, and/or CoO nanoparticles with the aim of evaluating the synergistic effect between active phase and the support in heavy oil on-site upgrading. Catalysts were characterized by chemical composition through X-ray Fluorescence, surface area, and pore size distribution through N2 adsorption/desorption, catalyst acidity by temperature programmed desorption (TPD), and metal dispersion by pulse H2 chemisorption. Batch adsorption experiments and catalytic steam gasification of adsorbed heavy fractions was carried out by thermogravimetric analysis and were performed with heavy oil model solutions of asphaltenes and resins (R–A) in toluene. Effective activation energy estimation was used to determine the catalytic effect of the catalyst in steam gasification of Colombian EHO. Additionally, R–A decomposition under inert atmosphere was conducted for the evaluation of oil components reactions with active phases and steam atmosphere. The presence of a bimetallic active phase Inc.reases the decomposition of the heavy compounds at low temperature by an increase in the aliphatic chains decomposition and the dissociation of heteroatoms bonds. Also, coke formation after steam gasification process is reduced by the application of the bimetallic catalyst yielding a conversion greater than 93%. Full article
