  • Process and system for producing light olefins from inferior oils
    Publication number: 20220064552
    Abstract: A process for producing light olefins from inferior oils includes the steps of: subjecting an inferior oil to a thermal conversion reaction in the presence of hydrogen to obtain a conversion product; separating the conversion product to obtain a first separated product; separating the first separated product to obtain an upgraded oil and a pitch; subjecting the upgraded oil to hydro-upgrading to obtain a hydro-upgraded oil; separating the hydro-upgraded oil to obtain a hydro-upgraded heavy oil; and subjecting the hydro-upgraded heavy oil to catalytic cracking to obtain a catalytic cracking product comprising a light olefin.

  • Process and system for upgrading low-quality oils
    Patent number: 11078434
    Abstract: Disclosed is a process and system for upgrading low-quality oils. The upgrading process comprises: (1) subjecting a low-quality oil to a conversion reaction in the presence of hydrogen and optionally in the presence of a conversion catalyst to obtain a conversion product, (2) processing the conversion product to obtain a first processed product, wherein the first processed product comprises a specific amount of a special component, and (3) subjecting the first processed product to extraction separation to obtain an upgraded oil and a pitch. The upgrading process and the upgrading system have the advantages of stable operation, high upgrading efficiency, environmental friendliness, low coke yield or high yield of upgraded oil.
