Abstract: The present disclosure generally relates to upgrading difficult to process heavy-oil. In particular, the disclosure relates to upgrading heavy oil and other high carbon content materials by using an integrated thermal-process (ITP) that utilizes anti-coking management and toluene insoluble organic residues (TIOR) management to directly incorporate lighter hydrocarbons into high molecular weight, low hydrogen content hydrocarbons such as thermally processed heavy oil products. This process can be integrated with other thermal processing schemes, such as cokers and visbreakers, to improve the conversion and yields from these integrated processes.

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.
