    • A process for upgrading crude oil fractions or other hydrocarbon oil feedstreams boiling in the range of 36° to 520° C., and preferably naphtha and gas oil fractions boiling in the range of 36° to 400° C., employs a solid adsorption material to lower sulfur and nitrogen content by contacting the hydrocarbon oil, and optionally a viscosity-reducing solvent, with one or more solid adsorbents such as silica gel or silica, silica alumina, alumina, attapulgus clay and activated carbon in a mixing vessel for a predetermined period of time; passing the resulting slurry to a membrane separation zone, optionally preceded by a primary filtration step (i.e., single stage or multiple stages), to separate the solid adsorption material with the adsorbed sulfur and nitrogen compounds from the treated oil; recovering the upgraded hydrocarbon product having a significantly reduced nitrogen and sulfur content as the membrane permeate; mixing the solid adsorbent material with one or a combination of aromatic solvents such as toluene, benzene, the xylenes and tetrahydrofuran to remove and stabilize the sulfur and nitrogen compounds; transferring the solvent to a fractionation tower to recover the solvent, which can be recycled for use in the process; and recovering the hydrocarbons that are rich in sulfur and nitrogen for processing in a relatively small high-pressure hydrotreating unit or transferring them to a fuel oil pool for blending.

    • A delayed coking process includes: a. introducing a fresh hydrocarbon feedstock containing undesirable sulfur and/or nitrogen compounds for preheating into the lower portion of a coking unit product fractionator; b. introducing at least a portion of an intermediate fraction derived from the fractionator and at least one adsorbent material that selectively adsorbs sulfur- and/or nitrogen-containing compounds into a mixing zone to form an adsorbent slurry stream; c. discharging a bottoms fraction from the fractionator; d. adding all or a portion of the slurry stream to the bottoms fraction to form a mixed coking unit feedstream; e. heating the mixed feedstream in the coking unit furnace to a predetermined coking temperature; and f. passing the heated mixed feedstream to a drum of the delayed coking to produce a delayed coking product stream while depositing the adsorbent material having adsorbed sulfur and/or nitrogen compounds with the coke in the coking drum.
