TL;DR: In this article, an effort has been made to improve the sulfur and nitrogen tolerance in the conversion of n-hexadecane by introducing palladium and magnesium as additives, leading to the improvement of sulfur tolerance.

TL;DR: In this paper, SK Corporation of Korea developed a unique process, SK hydrodesulfurization (HDS) pretreatment technology, to produce ultralow sulfur diesel (ULSD) with pretreatment of the middle distillate-range petroleum fractions.

TL;DR: In this paper, a method of simultaneously manufacturing high quality Naphthenic base oil and heavy base oil using a single catalyst system is presented, by subjecting an oil fraction (slurry oil or light cycle oil) produced by fluid catalytic cracking to hydrotreating, catalytic dewaxing and hydrofinishing.

TL;DR: In this paper, a method of manufacturing high-quality base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline was proposed.

TL;DR: In this article, a method of producing aromatics and light paraffins from hydrocarbonaceous oils derived from oil, coal or wood was proposed, including partially saturating and hydrocracking the oil derived from oils in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation/reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbon component having 5 or fewer carb
