METHOD OF HYDROCRACKING SELECTIVE IN RELATION TO IMPROVED DISTILLATE AND IMPROVED OUTPUT OF LUBRICANTS AND THEIR PROPERTIES Russian patent published in 2015 - IPC C10G71/00 C10G47/18 C10G65/10 C10G65/12 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the method including hydrocracking of the raw stock flow being selective for the converted products in range of boiler temperatures of the distillate, and producing the unconverted products suitable for use as lubricants including: provision of raw stock flow, hydrocracking of raw stock flow with creation of the hydrocracking product, and separation of the hydrocracking product to the converted product, and unconverted products, at that the raw stock flow is made by: hydrotreating of the crude oil fraction, with creation of the hydrotreated product, hydrocracking of the hydrotreated product at the stage of preliminary hydrocracking by flow of the hydrogen containing treating gas in the presence of the catalytic system of the preliminary hydrocracking at the effective conditions of the preliminary hydrocracking sufficient to achieve the conversion degree 50% maximum, with creation of the hydrotreated product subjected to the preliminary hydrocracking, and separation of the hydrotreated product subjected to the preliminary hydrocracking to the preliminary converted product, and preliminary unconverted product such, that the preliminary unconverted product is flow of the raw stock - vacuum gasoil.

EFFECT: converted fraction shows high output of the distillate and set or improved properties of the distillate fuel, and unconverted fraction shows improved properties especially useful for the lubricants.
