A series of articles dealing, in as simple a way as possible, with the basic facts of lubrication, lubricants, their selection and prescription, specification, application, and testing. This series is primarily intended for students, engineering personnel who may be unfamiliar with certain aspects and others who, one way or another, are interested in this important subject.

Bull, S. A hydrotreating process for manufacturing lube oils of HVI quality or better has been developed and implemented on a commercial scale. Development included catalyst optimization, selection of operating conditions and evolution of product specifications. The process operates at moderate hydrogen pressure and has been proved in seven years' commerciai operation. Extensive product development has shown that hydrotreated base oils give products at least equal in performance to those based on extracted oils, with notable advantages in some applications. Premium quality multigrade engine oils formulated from VHVI base oils show significant advantages over HVI formulations in low temperature and volatility properties at much lower cost than synthetic-based lubricants.

Most products of Crude oil processing are usually grouped into three categories: light distillates LPG, gasoline, naphtha , middle distillates kerosene, diesel , heavy distillates and residuum fuel oil, lubricating oils, wax, tar. You have to separate the different types of hydrocarbons to have anything useful. In the early days of the oil industry, lubricants The feedstocks that move into base oil production have alternative destinations in fuels operations and many of the by-products of base oil production move back to the fuels side for processing and blending. Some are predominantly naphthenes so yield a lubricating oil that is more sensitive to temperature changes than the paraffin-base crudes.
This invention relates to an improved method of preparing base stocks for lubricating oil with improved color, thermal and oxidative stability. More particularly, it relates to an improved method of preparing base stocks for lubricating oil with improved color, thermal and oxidative stability by varying the temperatures and pressures of the hydrofinishing process. It is well-known that lubricants are susceptible to deterioration by oxidation. Lubricants can be attacked by oxygen or air at high temperatures to form heavy dark viscous sludges, varnish and resins. Such deterioration reduces a lubricant's effectiveness to perform its required task.
Base oils, unlike essential oils, don't contain a concentrated aroma but most of them have a mild distinctive smell and don't evaporate. Now this recent news from Amyris is pretty interesting since I used to cover a little bit of the base oil industry when I wrote articles for Chemical Market Reporter before on lubricants, greases and waxes.
Неудачный выбор места, - прокомментировал Смит. - Халохот думал, что поблизости никого. Халохот какое-то время наблюдал за происходящим, потом скрылся за деревьями, по-видимому, выжидая. - Сейчас произойдет передача, - предупредил Смит.
Лейтенант рассказал вам про кольцо? - удивился Клушар, - Рассказал. - Что вы говорите! - Старик был искренне изумлен. - Я не думал, что он мне поверил.
Беккер задумался. Что это за имя такое - Капля Росы.
