A heavy hydrocarbon oil is mixed with one or more disulfide oil compounds and/or one or more oxidized disulfide oil compounds and, optionally, a homogeneous catalyst includes dissolved hydrogen, and the mixture is subjected to a delayed coking process to produce a liquid coking unit product stream for recovery and further processing, with the delayed coking being completed in a reduced residence time as compared to the delayed coking of the heavy hydrocarbon oil without the DSO and/or ODSO compounds.

Measuring the real corrosion risk that organosulfur compounds present in refinery operations is simplified by first measuring the total sulfur content of a sample of a hydrocarbon material. The sample is then combined with a specific quantity of high surface area iron powder at a temperature representative of the highest temperature anticipated in a refining process for a period of time, such as one hour. The solid phase is then removed, and the total sulfur content is again measured. The difference between the before and after represents the total reactive sulfur of the hydrocarbon material. The hydrocarbon material is then blended with other hydrocarbon materials to create a stream that can be optimized to utilize the maximum volume of the lowest cost feedstock while managing the corrosion risk to the refinery equipment and piping.

The present technology provides a process that includes heating a first mixture of elemental sulfur and particles comprising an alkali metal sulfide in a liquid hydrocarbon to a temperature of at least 150 C., to provide a sulfur-treated mixture comprising agglomerated particles; and separating the agglomerated particles from the sulfur-treated mixture to provide a desulfurized liquid hydrocarbon and separated solids. This process may be used as part of a suite of processes for desulfurizing liquid hydrocarbons contaminated with organosulfur compounds and other heteroatom-based contaminants. The present technology further provides processes for converting carbon-rich solids (e.g., petroleum coke) into fuels.

Disclosed is a process for the alteration of the ratio of the specific gravities of the oil and water phases resulting from the conversion of biomass to liquid products, the reduction of the conductivity and of metals of the product mixture, which each can aid in the removal of solids contained in the oil phase; and a liquid-liquid extraction method for partitioning desirable carbon containing compounds into the oil phase and undesirable carbon containing compounds into the water phase.

The invention involves an integrated process in which a hydrocarbon feedstock is treated with a caustic (alkaline) extraction to remove sulfides, disulfides, and mercaptans. These extracted materials are further treated, and are then used to activate hydrotreating catalysts.
