Special Issue Information

Dear Colleagues,

Following the success of the first Global Conference on Catalysis and Reaction Engineering at Las Vegas, USA on October 19-21, 2017, we take pleasure to announce second edition of the conference. The 2^nd edition of Global Conference on Catalysis, Chemical Engineering & Technology (CAT 2018) will take place at Holiday Inn Rome, Italy from 13^th to 15^th September 2018. CAT 2018 will provide a dedicated platform to peer researchers, young inspired scientists, academicians, and industrialists to meet, discuss and share the knowledge that’s still more to be revealed in the field of Catalysis and Chemical Engineering. The aim of the conference is to bring together leading experts in the field of catalysis, chemical engineering and technology. The series of talks, poster presentations, workshops, discussions and networking events will keep participants engaged in learning and making new connections at this Catalysis, Chemical Engineering & Technology Conference.

The present Special Issue will feature the works presented at CAT 2018 that promote linkage of the catalytic science, ingineering and technology. Authors with expertise in any topic of catalysis are cordially invited to submit their manuscripts to this Special Issue of Catalysts. Significant full papers and review articles are very welcome. The topics of the conference will cover various aspects of catalysis in all of its diversity, as well as other areas on the boundaries such as environmental protection, energy, sustainability, green chemistry, fine chemistry, biotransformation, surface chemistry and enzyme and microbial technology.

More information about the conference can be found at https://catalysis-conferences.magnusgroup.org/.

Scientists are cordially invited to contribute original research papers or reviews in all aspects of catalysis, chemical engineering and technology to this special issue of Catalysts.

Abstract

Co-containing Beta zeolite catalysts prepared by a wet impregnation and two-step postsynthesis method were investigated. The activity of the catalysts was examined in Fischer-Tropsch synthesis (FTS), performed at 30 atm and 260 °C. The physicochemical properties of all systems were investigated by means of X-ray diffraction (XRD), in situ XRD, temperature programmed desorption of ammonia (NH₃-TPD), X-ray Photoelectron Spectroscopy (XPS), temperature programmed reduction of hydrogen (TPR-H₂), and transmission electron microscopy (TEM). Among the studied catalysts, the best results were obtained for the samples prepared by a two-step postsynthesis method, which achieved CO conversion of about 74%, and selectivity to liquid products of about 86%. The distribution of liquid products for Red-Me-Co₂₀Beta was more diversified than for Red-Mi-Co₂₀Beta. It was observed that significant influence of the zeolite dealumination of mesoporous zeolite on the catalytic performance in FTS. In contrast, for microporous catalysts, the dealumination did not play such a significant role and the relatively high activity is observed for both not dealuminated and dealuminated catalysts. The main liquid products of FTS on both mesoporous and microporous catalysts were C₁₀-C₁₄ isoalkanes and n-alkanes. The iso-/n-alkanes ratio for dealuminated zeolite catalysts was three times higher than that for not dealuminated ones, and was related to the presence of different kind of acidic sites in both zeolite catalysts.

Hydroxymethylation of Furfural to HMF with Aqueous Formaldehyde over Zeolite Beta Catalyst

by Shun Nishimura and Atsuki Shibata

Abstract

Hydroxymethylation of 2-furaldehyde (furfural) toward 5-hydroxymethyl-2-furaldehyde (HMF) was examined in this work among various zeolites with an aqueous formaldehyde as a reagent in a batch and a flow reactor system. It was found that the zeolite beta gave high activity and good reusability with calcination treatment before each run for the target reaction in the batch system. The unique stability of the HMF yield in the liquid-flow system was also observed only in the case of zeolite beta. The effect of the SiO₂/Al₂O₃ ratio in the zeolite beta suggested that hydrophobicity would be an important factor in faster hydroxymethylation with an aqueous formaldehyde reagent. The highest turnover frequency (TOF) for HMF production was found to be 2.4 h⁻¹ in the case of zeolite beta with SiO₂/Al₂O₃ = 440 in the batch reactor system. An approximately 30% yield for HMF was achieved under optimum conditions for zeolite beta catalysts. Full article

Abstract

A series of cerium-based UiO-66 was obtained via hydrothermal and sonochemical methods, using the same quantities of reagents (cerium ammonium nitrate (CAN), terephthalic acid (H₂BDC)) and solvents) in each synthesis. The impact of synthesis method and metal to linker ratio on the structural and textural properties of obtained UiO-66(Ce), as well as their composition in terms of Ce⁴⁺/Ce³⁺ ratio, structure defects resulting from missing linker, and CO₂ adsorption capacity was discussed. By using typical characterization techniques and methods, such as XRD, N₂ and CO₂ sorption, TGA, XPS, and SEM, it was shown that the agitation of reacting mixture during synthesis (caused by stirring or ultrasounds) allows to obtain structures that have more developed surfaces and fewer linker defects than when MOF was obtained in static conditions. The specific surface area was found to be of minor importance in the context of CO₂ adsorption than the contribution of Ce³⁺ ions that were associated with the concentration of linker defects.

Transient Operation: A Catalytic Chemoselective Hydrogenation of 2-Methyl-3-Butyn-2-ol via a Cooperative Pd and Radiofrequency Heating Directed Kinetic Resolution

by Duaa Raja, Jabbar Gardy, Ali Hassanpour, Chun-Yu Ho and Javier Fernandez Garcia

Abstract

The effect of periodic temperature oscillations has been studied for the hydrogenation of 2-methyl-3-butyn-2-ol over a Pd-based catalyst in a micro-trickle bed reactor. This hydrogenation was investigated using a radiofrequency heated reactor under transient conditions using temperature cycling. The dynamic operation using this configuration was found to increase both conversion and selectivity towards 2-methyl-3-buten-2-ol compared to the steady-state operation with an improvement of up to 24% for the selectivity being observed. The developments made here also result in a lower activation energy in comparison to previous data, providing a starting point for radiofrequency heating to enhance reaction rate through the exploitation of thermal cycling at production scale.
