FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to the diesel fuel production method from the hydrocarbons stream, including: hydrocarbons stream feeding to the hydrotreating reactor; said hydrocarbons stream hydrotreating in the presence of hydrogen stream and pre-purification catalyst with obtaining of the pre-purified output stream; said pre-purified output stream separating into the vaporous pre-purified stream and liquid pre-purified stream; performance of the said liquid pre-purified stream hydrocracking in the presence of hydrocracking catalyst and hydrogen with production of the output hydrocracking stream; said vapor pre-cleaned stream mixing with all said hydrocracking output stream with production of the mixed hydrocracking output stream; fractionating of at least part of the said mixed hydrocracking output stream with production of the diesel fuel stream; and the said diesel fuel stream hydrotreating in the presence of the hydrotreating hydrogen stream and hydrotreating catalyst with production of the hydrotreating output stream. Invention also relates to this method implementation device.
EFFECT: use of the proposed invention allows to produce larger amount of diesel fuel meeting the requirements for this product.
