A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.

A process for upgrading pyrolysis tar to higher value products. More particularly, this invention relates to the upgrading of steam cracker tar using relatively small amounts of a transition metal sulfide-containing particulate catalyst dispersed throughout the tar chargestock and in the presence of hydrogen, at relatively mild hydroconversion conditions.

A hydroprocessing system involves introducing heavy oil and in situ formed metal sulfide catalyst particles, or a catalyst precursor capable of forming metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The metal sulfide catalyst particles are formed in situ by 1) premixing a catalyst precursor with a hydrocarbon diluent to form a precursor mixture, 2) mixing the precursor mixture with heavy oil to form a conditioned feedstock, and 3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil to form the metal sulfide catalyst particles in situ in the heavy oil. The in situ formed metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.
