• Kinetic modeling for steam reforming of naphtha surrogates on NiMgAl catalyst. The model discrimination was conducted based artificial neural networks. Ab initio (DFT) calculations allow further refinements and corroborations. selected kinetic satisfactorily captures catalyst activity selectivity. validated a wider set operating conditions feedstocks. Steam hydrocarbons is will be, in the sho...

"SEQUAH ON CLAPHAM COMMON" is the legend attached to a small Victorian oil-painting in the Wellcome Institute library (plate 1).1 The setting, Clapham Common, is known to Londoners as a grassy open space a mile or two south of the river Thames, but the name "Sequah" today means, to most people, nothing. Yet for a brief period around 1890, Sequah was perhaps the most celebrated medical operator ...

The debutanizer column is an important unit operation in petroleum refining industries as it is the main column to produce liquefied petroleum gas as its top product and light naphtha as its bottom product. This system is difficult to handle from a control standpoint due to its nonlinear behavior, multivariable interaction and existence of numerous constraints on both its manipulated and state ...

Activity-guided isolation of the fermentation broth of the deep-sea derived fungus Acaromyces ingoldii FS121, which was obtained from the China South Sea, yielded a new naphtha-[2,3-b]pyrandione analogue, acaromycin A (1) and a new thiazole analogue, acaromyester A (2), as well as the known compound (+)-cryptosporin (3). Their structures, including absolute configurations, were determined by ex...

A facile synthesis of novel polycyclic heterocycles namely naphthaquinoxaline and naphthazaquinoxaline derivatives is carried out by the reaction of lapachol and β-lapachone, naturally occurring naphthoquinones with o-phenylene diamine and 2,3-diaminopyridine. Regioselectivity in the reaction of β-lapachone with 2,3-diaminopyridine is confirmed by single crystal X-ray diffraction of a represent...

Catalytic naphtha reforming is one of the most important processes in which, low quality naphtha is converted into high octane motor gasoline. In this study, a mathematical model was developed and was used for investigation the effect of temperature, pressure, hydrogen to hydrocarbon ratio on the octane number, the yield of product and the undesirable phenomena of coke deposition in a semiregen...
