FIELD: oil, gas and coke-chemical industry.
SUBSTANCE: invention relates to a method and a system for producing fuel oil and use thereof, as well as to oil fuel and use thereof. Method includes: (1) bringing the sulphur-containing oil feedstock into contact with an alkali metal to perform a preliminary reaction to obtain a material after a preliminary reaction, wherein the preliminary reaction is carried out in the absence of hydrogen; (2) contacting the material after the preliminary reaction with the agent providing hydrogen for the hydrogenation reaction; (3) separation of the material obtained at step (2) to obtain a liquid-phase product, oil fuel, and a solid mixture.
EFFECT: conversion into oil fuel of low-grade and cheap oil raw material, such as heavy residual oil products, with high efficiency of using alkali metals and a safe and reliable method.
