Revisiting the Role of Mass and Heat Transfer in Gas–Solid Catalytic Reactions

Processes (2020)

Riccardo Tesser E. Santacesaria

The tremendous progress in the computing power of modern computers has in the last 20 years favored the use of numerical methods for solving complex problems in the field of chemical kinetics and of reactor simulations considering also the effect of mass and heat transfer. Many classical textbooks dealing with the topic have, therefore, become quite obsolete. The present work is a review of the role that heat and mass transfer have in the kinetic studies of gas–solid catalytic reactions. The scope was to collect in a relatively short document the necessary knowledge for a correct simulation of gas–solid catalytic reactors. The first part of the review deals with the most reliable approach to the description of the heat and mass transfer outside and inside a single catalytic particle. Some different examples of calculations allow for an easier understanding of the described methods. The second part of the review is related to the heat and mass transfer in packed bed reactors, considering the macroscopic gradients that derive from the solution of mass and energy balances on the whole reactor. Moreover, in this second part, some examples of calculations, applied to chemical reactions of industrial interest, are reported for a better understanding of the systems studied.

From Homogeneous to Heterogeneous Catalysts in Biodiesel Production

Industrial & Engineering Chemistry Research (2007)

Martino Di Serio M. Cozzolino Maddalena Giordano Riccardo Tesser P. Patrono

The production of biodiesel as a fuel in diesel engines greatly increased in recent years and is expected to grow more and more in the near future. Increasing biodiesel consumption requires optimized production processes allowing high production capacities, simplified operations, high yields, and the use of more economic feedstocks such as waste oils and fats. However, the latter often contain large amounts of free fatty acids and cannot be processed with the commonly practiced technology based on the use of alkaline catalysts in the homogeneous phase that requires the use of highly refined oil as raw materials. Therefore, the development of processes for low-cost biodiesel production requires the individuation of heterogeneous catalysts that are very efficient in promoting the transesterification reaction also in the presence of free fatty acids and water, allowing the prompt separation of pure glycerol and not requiring expensive purification of this byproduct. In the present contribution, the performances of different heterogeneous catalysts are compared both in the absence and in the presence of free fatty acids. In some cases, the resistance of the catalysts to the presence of water and the eventual deactivating effects after the first use have also been tested. The catalysts considered are both basic and acidic in nature, such as hydrotalcite, MgO, TiO2 grafted on silica, vanadyl phosphate, and different metals-substituted vanadyl phosphate of the type Me(H2O)xVO1-xPO4·2H2O, where Me is a trivalent cation such as Al, Ga, Fe, and Cr and where x = 0.18−0.20. Finally, the understanding of the kinetic behavior of the most stable catalyst TiO2/SiO2 has been deepened.

Fluoride adsorption on hydroxyapatite: From batch to continuous operation

Journal of environmental chemical engineering (2024)

Vincenzo Russo Antonio D’Angelo Clorinda Salvi Rosanna Paparo M. Fortunato

In the present paper, the removal of fluoride from drinking was investigated via adsorption technique, an important contaminant that could cause serious threat to human health. The challenge of this work is the scale-up from batch to continuous operation, including regeneration of the adsorbent, using a commercial hydroxyapatite, namely Fuorandel®. Adsorption Dynamic Intraparticle Model (ADIM) was used to describe the data collected in batch mode, obtaining important parameters to design a continuous adsorption column, such as: surface diffusivity, DS, and tortuosity, τ. Those parameters were fixed to simulate the experimental data collected in a continuous device obtaining good results. Finally, the sorbent regeneration in a batch system was investigated, optimizing the conditions to enhance Fluorandel® recovery. The present paper shows clearly the potential application of the selected sorbent, giving all the tools needed to scale-up the operation at industrial level.

Reactive Chromatography Applied to Ethyl Levulinate Synthesis: A Proof of Concept

Processes (2021)

Carmelina Rossano Claudio Luigi Pizzo Riccardo Tesser Martino Di Serio Vincenzo Russo

Levulinic acid (LA) has been highlighted as one of the most promising platform chemicals, providing a wide range of possible derivatizations to value-added chemicals as the ethyl levulinate obtained through an acid catalyzed esterification reaction with ethanol that has found application in the bio-fuel market. Being a reversible reaction, the main drawback is the production of water that does not allow full conversion of levulinic acid. The aim of this work was to prove that the chromatographic reactor technology, in which the solid material of the packed bed acts both as stationary phase and catalyst, is surely a valid option to overcome such an issue by overcoming the thermodynamic equilibrium. The experiments were conducted in a fixed-bed chromatographic reactor, packed with Dowex 50WX-8 as ion exchange resin. Different operational conditions were varied (e.g., temperature and flow rate), pulsing levulinic acid to the ethanol stream, to investigate the main effects on the final conversion and separation efficiency of the system. The effects were described qualitatively, demonstrating that working at sufficiently low flow rates, LA was completely converted, while at moderate flow rates, only a partial conversion was achieved. The system worked properly even at room temperature (303 K), where LA was completely converted, an encouraging result as esterification reactions are normally performed at higher temperatures.

Kinetics of the Oxidative Dehydrogenation of Ethanol to Acetaldehyde on V₂O₅/TiO₂−SiO₂ Catalysts Prepared by Grafting

Industrial & Engineering Chemistry Research (2004)

Riccardo Tesser V. Maradei Martino Di Serio E. Santacesaria

Catalysts that are very active and selective in the oxidative dehydrogenation of ethanol to acetaldehyde have been prepared by grafting vanadyl triisopropoxide onto a silica support whose surface was coated with TiO2. Together with acetaldehyde, small amounts of byproducts were obtained, including acetic acid, acetals, and CO2. The kinetic behaviors of the catalysts were studied in the temperature range 100−180 °C, by changing the ethanol residence time, the molar ratio between the reagents, and the vanadium load. A four-step mechanism was adopted, consisting of the following steps: (i) dissociative adsorption of ethanol onto vanadium, (ii) α-hydrogen withdrawal by the metal to form acetaldehyde and a hydride group, (iii) oxidation of the formed hydride, and (iv) dehydration of the vanadium site to restore the original active site. This mechanism can be simplified, and the resulting kinetic expression is similar to a Mars and van Krevelen kinetic expression. The reaction is well-described by this kinetic model. The activation energy (11 kcal/mol) obtained for the main reaction is in agreement with the values reported in the literature for the same type of catalyst. The reaction rates depend linearly on the vanadium load.

Comparison of Different Reactor Types Used in the Manufacture of Ethoxylated, Propoxylated Products

Industrial & Engineering Chemistry Research (2005)

Martino Di Serio Riccardo Tesser E. Santacesaria

Ethoxylation and/or propoxylation are performed in industry to produce surfactants and polyglycols. The reaction is normally promoted by an alkaline catalyst (such as NaOH or KOH) and is performed in gas−liquid stirred reactors, Venturi loop reactors, and spray tower loop reactors. In the first two types of reactors, the gas phase is dispersed into the liquid phase; on the contrary, in the latter case, the liquid phase is dispersed into the gaseous one. In this paper, the key factors in ethoxylation/propoxylation technology will be examined: (i) the types of reactors employed and their performances; (ii) the role of kinetics and mass transfer in the process; and (iii) safety.
