  • HYDROREFINING METHOD FOR HYDROCARBON OIL
    Publication number: 20100206770
    Abstract: The invention provides a hydrocarbon oil hydrorefining method, characterized by including providing a mixture of a heavy hydrocarbon oil and a hydrocarbon oil exhibiting an effect of increasing dissolved hydrogen concentration; mixing the oil mixture, which is subjected to hydrorefining, with hydrogen; and causing the resultant mixture to pass through a reactor for carrying out hydrorefining. The method can enhance performance in hydrorefining of the heavy oil.
