    Assessment of the Oxidative Desulfurization of Middle Distillate Surrogate Fuels with Spectroscopic Techniques by Eleni Syntyhaki, Anastasia Detsi, Dimitrios Karonis

    Published 2020-01-01
    “…The goal of this study was the implementation of a simple and economical oxidative and extractive system for the desulfurization of surrogate mixtures with an intermediate sulfur concentration 1% w/w, at the mild temperature of 70°C, and without the use of supplementary and assisting methods such as heterogeneous catalysis or ultrasound irradiation. The sulfur content was estimated using X-ray fluorescence. …”

    Recent catalytic advances in the production of adipic acid and its esters from bio-based C6 molecules and carbon dioxide by Dinesh Kumar Mishra, Cong Chien Truong, Yeongin Jo, Young-Woong Suh

    Published 2025-12-01
    “…Here, we review the eco-friendly valorization of renewable bio-based C6 molecules, such as 5-hydroxymethylfurfural derivatives (e.g. 2,5-furandicarboxylic acid, 2,5-tetrahydrofuran dicarboxylic acid, and 1,6-hexanediol), sugar acid derivatives (i.e. d-glucaric acid, d-glucarate-6,3-lactone esters, glucarodilactone, mucic acid, and muconic acid), and CO2 into AA and its esters through a wide assortment of homogeneous and heterogeneous catalysis. The aspects of catalyst evaluation, operating conditions, and reaction mechanisms are comprehensively discussed. …”
