Cracking (chemistry)

Handbook of Petroleum Processing pp Cite as. Hydrocracking is a flexible catalytic refining process that can upgrade a large variety of petroleum fractions. Hydrocracking is commonly applied to upgrade the heavier fractions obtained from the distillation of crude oils, including residue. The process adds hydrogen which improves the hydrogen to carbon ratio of the net reactor effluent, removes impurities like sulfur to produce a product that meets the environmental specifications, and converts the heavy feed to a desired boiling range. The chemistry involves the conversion of heavy molecular weight compounds to lower molecular weight compounds through carbon-carbon bond breaking and hydrogen addition.

Hydrocrackers designed for residue conversion employ ebullated bed e-bed reactors or slurry-phase reactors. Fixed-bed and e-bed hydrocrackers employ dual-function hydrocracking catalysts, which contain both acid sites and hydrogenation sites. Acidity comes from amorphous aluminosilicates ASA , crystalline zeolites, and related materials such as silica-alumina phosphates SAPO.

The properties of catalyst were studied by N 2 adsorption-desorption, X-ray diffraction, and scanning electron microscopy. The reaction was conducted in cyclohexane under 0. Amounts of organic compounds which fall into the categories of homologues of benzene and naphthalene were detected. It suggested that the catalyst could effectively catalyze the cleavage of C-C-bridged bonds. As an important chemical process, direct coal liquefaction DCL could be a feasible option to directly convert coals into liquid fuels or chemicals [ 1 , 2 ].

Hydrocracking in Petroleum Processing

Переключая передачи, Беккер мчался вперед между белокаменными стенами. Улочка имела множество поворотов и тупиков, и он быстро потерял направление. Он поднял вверх голову, надеясь увидеть Гиральду, но окружившие его со всех сторон стены были так высоки, что ему не удалось увидеть ничего, кроме тоненькой полоски начинающего светлеть неба. Беккер подумал, где может быть человек в очках в тонкой металлической оправе.

 Чед, уверяю тебя, в шифровалке творится что-то непонятное. Не знаю, почему Фонтейн прикидывается идиотом, но ТРАНСТЕКСТ в опасности. Там происходит что-то очень серьезное. - Мидж.

Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева. Кабинет номер 9А197. Директорские апартаменты. В этот субботний вечер в Коридоре красного дерева было пусто, все служащие давно разошлись по домам, чтобы предаться излюбленным развлечениям влиятельных людей.
