Systems for increasing catalyst concentration in heavy oil and/or coal resid hydrocracker

Номер: US20120009094A1
Автор: Roger K. Lott, Yu-Hwa Chang
Принадлежит: Individual

Systems for hydrocracking a heavy oil feedstock employ a colloidally or molecularly dispersed catalyst (e.g., molybdenum sulfide) which provide for concentration of the colloidally dispersed catalyst within the lower quality materials requiring additional hydrocracking. In addition to increased catalyst concentration, the inventive systems and methods provide increased reactor throughput, increased reaction rate, and of course higher conversion of asphaltenes and lower quality materials. Increased conversion levels of asphaltenes and lower quality materials also reduces equipment fouling, enables the reactor to process a wider range of lower quality feedstocks, and can lead to more efficient use of a supported catalyst if used in combination with the colloidal or molecular catalyst.

A hydroprocessing method and system involves introducing heavy oil and well-dispersed metal sulfide catalyst particles, or a catalyst precursor capable of forming the well-dispersed metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The well-dispersed or in situ metal sulfide catalyst particles are formed 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 well-dispersed or in situ metal sulfide catalyst particles. The well-dispersed or in situ metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.

Instead of attempting to process vacuum resid in a fixed bed processing unit, vacuum resid is deasphalted to form a deasphalted oil and deasphalter residue or rock. The rock can then be hydroprocessed in a fixed bed reaction zone, optionally after combining the rock with an aromatic co-feed and/or a hydroprocessing solvent. This can allow for improved conversion of the deasphalter rock and/or improved combined conversion of the deasphalter rock and deasphalted oil. 1.
