  • Patent number: 11518949
    Abstract: A process for producing propylene and a low-sulfur fuel oil component, comprising the steps of contacting a heavy feedstock oil with a solvent for extraction separation to obtain a deasphalted oil and a deoiled asphalt; contacting the deasphalted oil and optionally a light feedstock oil with a catalytic conversion catalyst for reaction to obtain a reaction product comprising propylene; separating the reaction product to obtain a catalytic cracking distillate oil, and subjecting the catalytic cracking distillate oil to hydrodesulfurization to obtain a low-sulfur hydrogenated distillate oil, wherein the low-sulfur hydrogenated distillate oil and/or the deoiled asphalt is suitable for use as a fuel oil component. The process allows the conversion of saturated hydrocarbons in the heavy feedstock into propylene, eliminates the use of saturated hydrocarbons in the fuel oil component, and thus has better economic and social benefits.

  • Patent number: 11473024
    Abstract: Systems and methods are provided for increasing the portion of a pyrolysis tar fraction that can be hydroprocessed by using a physical particle size reduction process on at least a portion of the pyrolysis tar fraction. The physical particle size reduction process can reduce the percentage of particles in the pyrolysis tar fraction that have a particle size of 75 ?m or greater, or 50 ?m or greater. It has been unexpectedly discovered that at least a portion of the particles having a size of 75 ?m or less, or 50 ?m or less, can be effectively hydroprocessed to form products of greater value while still reducing or minimizing the amount of fouling or plugging in a hydroprocessing catalyst bed. By increasing the number of particles having a size of 75 ?m or less, or 50 ?m or less, while selectively removing larger particles from the SCT fraction, a higher yield of hydrocarbon products can be achieved for a feed containing an SCT fraction.
