This invention describes a novel and efficient processing scheme that can be used to transform a vacuum residue feedstock into 0.5 wt % sulfur bunker fuel that fulfills the specifications required by the International Maritime Organization (IMO).

Processing scheme for production of low sulfur bunker fuel

The integration of hydrogen and methanol production within a coal liquefaction, petroleum refinery or biomass conversion facility resulting in the unanticipated benefits of lower carbon dioxide (CO) production, net emissions, and higher carbon and thermal efficiencies is the subject of this invention.

Integrated coal liquefaction, petroleum or biomass facility with decreased carbon dioxide production and higher carbon and thermal efficiencies

The invention described herein relates to a novel process to create carbon black feed stocks derived from coal by utilizing direct coal liquefaction resulting in an economic process for producing carbon black feedstock. Moreover, relative to the current state of the art (use of FCC slurry oil), the invention process will be significantly more profitable when oil prices increase.

Carbon black feedstock from direct coal liquefaction

This invention utilizes a novel method and set of operating conditions to efficiently and economically process a potentially very fouling hydrocarbon feedstock. A multi-stage catalytic process for the upgrading of coal pyrolysis oils is developed. Coal Pyrolysis Oils are highly aromatic, olefinic, unstable, contain objectionable sulfur, nitrogen, and oxygen contaminants, and may contain coal solids which will plug fixed-bed reactors. The pyrolysis oil is fed with hydrogen to a multi-stage ebullated-bed hydrotreater and hydrocracker containing a hydrogenation or hydrocracking catalyst to first stabilize the feed at low temperature and is then fed to downstream reactor(s) at higher temperatures to further treat and hydrocrack the pyrolysis oils to a more valuable syncrude or to finished distillate products. The relatively high heat of reaction is used to provide the energy necessary to increase the temperature of the subsequent stage thus eliminating the need for additional external heat input. A refined heavy oil product stream is recycled to the fresh feed to minimize feedstock fouling of heat exchangers and feed heaters.

Process for upgrading coal pyrolysis oils

A multi-stage catalytic process for the direct liquefaction of coal is utilized with a hydrotreater to first liquefy and subsequently treat the product in one integrated process. A fresh hydrogenation catalyst is used to reduce heteroatoms (S, N) from coal liquids in the downstream hydrotreater. This catalyst is then cascaded and re-used in the direct coal liquefaction process, first in the low temperature Stage 1, and then re-used in the high temperature Stage 2. Coal liquid products have very low contaminants and can be readily used to produce gasoline and diesel fuel. Catalyst requirements are substantially lowered utilizing this novel process.

Direct coal liquefaction with integrated product hydrotreating and catalyst cascading

This invention relates to a novel integrated hydroconversion process for converting heavy atmospheric or vacuum residue feeds and also converting and reducing impurities in the vacuum gas oil liquid product. This is accomplished by utilizing two residue hydroconversion reaction stages, two vapor-liquid separators, and at least two additional distillate ebullated-bed hydrocracking/hydrotreating reaction stages to provide a high conversion rate of the residue feedstocks.

Process for multistage residue hydroconversion integrated with straight-run and conversion gasoils hydroconversion steps

An improved process for heavy oil conversion and upgrading and a combined method for heavy oil conversion and vacuum gas-oil treatment are described herein. The method utilizes the creation and recycle of a separate product from the vacuum still, which is thereafter recycled back to the heavy oil conversion reactor. The result is the production of a higher quality medium gas oil product relative to the overall vacuum gas oil product which is acceptable for use in a typical vacuum gas oil treatment process. Additionally, there is a higher diesel yield selectivity from the heavy oil conversion unit.
