... feedstocks obtained from distinct oil sources and refinery processes were used in this work: kerosene, light gas oil (LGO) and heavy gas oil (HGO) from atmospheric distillation; light and middle gas oil (LGO/MGO) from delayed coking; light vacuum gas oil (LVGO) from vacuum distillation; and light cycle oil...

... Abstract. The deep reduction of sulphur and aromatics contents of middle distillates are required to qualify them as environmentally friendly. We have developed very flexible hydrotreating process schemes and new catalysts able to produce clean middle distillates and to satisfy the most...

Nifontova - G. D. Galpern - M. M. Kusakov - I. B. Ushakova - A. A. Suchkova * Abstract. The paper summarizes...

... Résumé. Les additifs capables d'abaisser le point d'écoulement des middle distillates n'ont été développés que récemment mais ont déjà reçu un accueil favorable de la part de l'industrie pétrolière durant les deux dernières années. Cette communication traite de quelquesuns des éléments...

... Synopsis The use of furfural as a selective solvent for the extraction of middle boiling petroleum distillates effects a reduction in sulfur content, an increase in cetane number, improvement in burning quality and upgrades catalytic cycle gas oils to virgin quality. Furfural extracted light...

... been developed. Chemical conversion (liquefaction) of gas to make gas transportable as a liquid and add value to the products is now a proven technology. The Shell Middle Distillate Synthesis (SMDS) process is well known as Shell's contribution to this novel way of gas utilisation and is applied...

... Abstract Two major classes of additives are finding increasing use in middle distillate fuels. One class of additives, which improves stability and reduces sludge formation, has been used for more than 15 years. The tests used to determine the amount and type of additive best suited for a fuel...

... Abstract: In view of the new diesel specifications introduced around the world, the demand for highquality middle distillates has grown significantly over the past decade. Gas oils deep hydrodesulfurization has achieved much attention since the tolerated sulfur content in diesel fuel is being...

..., good structure with fewer defects and stronger acidity. Most of acidity composed of B acid. - The CPB zeolite has weaker acidity which mainly contains L acid. - The FTY zeolite has good nitrogen tolerance. Increase middle distillate selectivity by using amorphous SiO2-AI2O3 to replace Ab03 Besides USY...

... and high pressures to produces middle distillate fractions containing di- ana hydrogenate and cleave fused-ring aromatic hydrocarbons to tricyclic aromatics with low fuel value. These aromatics are give alkylbenzenes. A potential alternative is to use bacteria currently upgraded by expensive high pressure...

... and thermo-catalytic cracking of different waste polymers were developed in a gas heated horizontal tube reactor using -500'C temperature. Products were separated into fractions of gases, gasoline, middle distillates and heavy oil. It was found that plastic wastes could be converted into gasoline and middle...

...-skimming refinery is to be converted into a 220 kbpd full conversion refinery conceived to deal with heavy sour and acidic crude oils and devoted to maximize high quality middle distillates output. The reasons that support a delayed coker'hydrocracker conversion configuration are thoroughly analyzed...

... of, and a purchaser of, middle distillate. It proved reasonably easy for production to implement the computer plan, and the shortage of middle distillate was converted into a surplus, until our middle distillate tanks were full. Using the Deuce computer we then attempted to set plans for five seaboard refineries...

... be multiple and cross-linked. While energy and climate change legislation would impact future growth of middle distillates – the largest group both in terms of refined products (> 30%) and consumption growth (1.6%-1.8%), advances in Refining technology would be influential from supply side, whereas new...

... (DTGU) in the Schwechat refinery which has looked best to fit to the existing units and infrastructure. Vacuum residue should be converted well above 40%, the produced vacuum distillate is thermally cracked to mainly middle distillates which can be further hydrotreated in conventional diesel...

... and middle distillate demand. CONCAWE has considered the changes that EU refineries will have to undergo in terms of new investments, total economic impact, energy consumption and CO2 emissions in order to cope with a number of plausible supply/demand scenarios at the 2015 horizon. The main factors affecting...

... (more middle distillates, lower gasoline demand but higher octane gasoline) and investments running into hundreds of billions of dollars will be needed globally in the coming decades, to meet this changing demand structure. Even if such investments are made, there will likely be a surplus of low-octane...

... of the petroleum refining industry. Today, this goal has become even more important as the demand for heavy fuel oil and known reserves of the lighter crudes continue to decline. The market for residual fuel oil has been shrinking because of the steady increase in demand for middle distillates. Therefore, research...
