  • Heavy oil hydrocracking process with multimetallic liquid catalyst in slurry bed
    Patent number: 6660157
    Abstract: The invention relates to a new and improved heavy oil hydrocracking process using a multimetallic liquid catalyst in a slurry-bed reactor, particularly an improvement of lightweight treatment of heavy oil in the petroleum processing technology. According to the present invention, a slurry-bed hydrocracking reactor and a highly dispersed multimetallic liquid catalyst are mainly applied during the process. A fixed-bed hydrotreating reactor is also used on line to enhance lightweight oil yield from heavy oil under normal pressure.
