The present disclosure provides a method of treating waste plastic pyrolysis oil. The method includes a first step of washing waste plastic pyrolysis oil with water and then removing moisture; a second step of mixing the waste plastic pyrolysis oil from which the moisture is removed and a sulfur source to prepare a mixed oil; a third step of hydrotreating the mixed oil with hydrogen gas in the presence of a hydrotreating catalyst; a fourth step of separating the hydrotreated mixed oil into a liquid stream and a gas stream to obtain liquid pyrolysis oil; and a fifth step of recovering hydrogen gas from the separated gas stream and recycling the recovered hydrogen gas to the third step.

The present invention relates to a method for upgrading heavy oil by using byproducts of coke production, and particularly provides a method for upgrading heavy oil comprising the steps of: a) mixing heavy oil with byproducts of coke production to produce a mixed liquid: and b) subjecting the mixed liquid to pyrolysis, the method allowing reduction of the amount of coke generated and thus being economical and effective.

A method of mitigating fouling in a delayed coking unit heater may include forming a plastic mixture including a plastic material and a carrier. The plastic mixture may be combined with a coker feedstock upstream of a coke drum.

A multi-stage process for reducing the environmental contaminants in an ISO8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process and a Detrimental Solids removal unit as either a pre-treating step or post-treating step to the core process. The Product Heavy Marine Fuel Oil complies with ISO 8217 for residual marine fuel oils and has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass and a Detrimental Solids content less than 60 mg/kg. A process plant for conducting the process is also disclosed.

A multi-stage process for transforming a high sulfur ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process that produces a Product Heavy Marine Fuel Oil that can be used as a feedstock for subsequent refinery process such as anode grade coking, needle coking and fluid catalytic cracking. The Product Heavy Marine Fuel Oil exhibits multiple properties desirable as a feedstock for those processes including a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process is also disclosed.

The present disclosure provides a marine fuel component produced from feedstock of biological origin and a method for producing the same. The present disclosure provides marine fuel blends containing the marine fuel component of biological origin and at least one additional marine fuel.

Catalyst fines can be removed from heavy oils, such as marine fuel oils, by introducing an additive in an effective amount to at least partially remove the catalyst fines, where the additive is an oxyalkylated acid-catalyzed alkylphenol formaldehyde resin and/or a Mannich condensate base resin copolymer.

A method for treating petroleum, petroleum fraction, or natural gas, the process comprising: adding a) a first component which is selected from material, particularly roots, of a plant of the genus Glycyrrhiza, and/or an arbuscular mycorrhizal fungi, and b) a second component which is selected from a plant material or -ingredient comprising plastids, algae and/or cyanobacteria,
to the petroleum, petroleum fraction, or natural gas.
