Topic Information

Dear Colleagues,

The 23rd Romanian International Conference on Chemistry and Chemical Engineering (RICCCE23; https://riccce.chimie.upb.ro/) is the main international scientific event held in Romania in the field of chemistry and chemical engineering. The aim of RICCCE23 is to provide a forum for the presentation and discussion of the main scientific achievements made in chemistry and chemical engineering fields and to establish contacts between scientists as well as companies involved in research and development. Gathering in Mamaia, Romania, the conference brings together the most prominent scientists of the chemistry and chemical engineering research community. The 23rd RICCCE conference will take place in September 2023 and, once again, will cover all major areas in chemistry and chemical engineering and feature the latest scientific results that are making an impact in fundamental research and applications. The topics for original papers aim to cover all aspects of chemistry and include, but are not limited to, the following: 1. Advanced Strategies in Chemical Engineering and Biotechnology; 2. Bioengineering and Biomedical Technologies; 3. Green Energy and Chemistry Concepts; 4. Nanosciences and Nanotechnology; 5. Pharmaceutical Engineering and Food Safety; and 6. Sustainability and Environmental Engineering. We welcome you to share your up-to-date knowledge, developed by you and/or your research group, with the 23rd Romanian International Conference on Chemistry and Chemical Engineering, hoping that we will collect valuable contributions to create a unique topic collection for MDPI journals.

The hydro-upgrading reaction behavior of model compound 1-hexene and FCC middle gasoline was investigated using a fixed-bed hydrogenation microreactor with a prepared La-Ni-Zn/H-ZSM-5 catalyst. The catalyst was prepared by wetness impregnation method, using hydrothermal treated H-ZSM-5 zeolite blended with alumina as the support, and La, Ni, Zn as the active metals. The reaction tests were carried out at 300–380 °C, 1.0 MPa, 1.5–3.0 h−1 (LSHV), and 300:1 v/v (H2/oil). Analyzing the changes in hydrocarbon components before and after hydro-upgrading elucidated the mechanistic pathways of olefin hydroisomerization and hydroaromatization. Based on these findings, a seven-lump kinetic model was established for the FCC middle gasoline hydro-upgrading process. Given the diversity and complexity of reaction products, they were grouped into seven lumps: normal paraffins, isoparaffins, linear olefins, branched olefins, cycloolefins, naphthenes, and aromatics. Kinetic parameters were estimated using the Levenberg–Marquardt algorithm and validated against experimental data. The results showed that the conversion of naphthenes to aromatics exhibited the highest activation energy and pre-exponential factor, resulting in the largest reaction rate increase within the 320–380 °C range. The model accurately predicted the product yields of FCC gasoline hydro-upgrading, with a relative error of less than 5%. These findings provide valuable guidance for the optimization, design, and operation of FCC gasoline hydro-upgrading units, as well as for catalyst development, with the aim of improving process efficiency and fuel quality.

The most commonly used homogeneous catalyst for fatty acid esterification is a corrosive sulphuric acid. However, this requires costly investment in non-corrosive equipment, presents a safety risk, is time consuming, and increases effluent generation. In this study, inorganic 3D heteroborane cluster strong acids are employed for the first time as homogeneous catalysts. Three novel isomeric tetrachlorido and tetrabromido derivatives of 3,3′-commo-bis[undecahydrido-closo-1,2-dicarba-3-cobaltadodecaborate](1−) [1−] were synthesised and fully characterised using a range of analytical techniques, including NMR, TLC, HPLC, MS, UV-Vis, melting point (MP), CHN analyses, and XRD. Ultimately, H3O[8,8′-Cl2-1−] was identified as the most efficient, reusable, and non-corrosive homogeneous catalyst for the esterification of four fatty acids. The reactions are conducted in an excess of alcohol at reflux. The effective absorption of water vapour provided by the molecular sieves maximises acid conversion. The hydrophobic dye Sudan black B was employed as an acid-base indicator to facilitate a comparison of the H0 acidity function of sulphuric acid and halogenated heteroboranoic acids when dissolved together in methanol. The 23Na NMR analysis demonstrated that the application of dry methanol resulted in the displacement of Na+ ions from zeolite, which subsequently exchanged the H3O+ ions of the acid. This process led to a gradual reduction in the efficiency of the catalysts, particularly with repeated use. The solution to this issue is to regenerate the catalyst on the ion exchanger following each reaction. In contrast to the published methods, our new approach meets 10 of 12 green chemistry principles. Full article
