Researchers Submit Patent Application, "Process for Hydrocracking Heavy Oil and Oil Residue with a Carbonaceouse Additive", for Approval (USPTO 20170267937)

By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Schleiffer, Andreas (Lauenbruck, DE); Yang, Hong (San Diego, CA), filed on February 12, 2015, was made available online on September 28, 2017.

The patent's assignee is Bp Europa Se.

News editors obtained the following quote from the background information supplied by the inventors: "Hydroprocessing (which may also be referred to as hydrocracking, hydrotreating, hydroconverting, hydroconversion or hydrogenative cracking/processing/converting/conversion/treating/treatment) of heavy oils and/or oil residues is a known process that may be used to form useful materials from crude oil components that have high initial boiling points (i.e. typically greater than about 385.degree. C. for atmospheric residue, greater than about 525.degree. C. for vacuum residue and between about 350.degree. C. and about 525.degree. C. for vacuum gas oil). In order to make hydroprocessing conditions more economically viable, metal catalysts may be used to facilitate the hydroprocessing. See e.g. U.S. Pat. No. 4,770,764, U.S. Pat. No. 8,372,776 and US 20110017636. However, such metal catalysts are expensive and may be prone to deactivation. Alternatively, non-metallic (that is to say, non-metallised) carbonaceous materials such as lignite coke may be used as an additive instead of the metal catalysts. See U.S. Pat. No. 5,064,523. Such carbonaceous additives, however, are typically very inefficient at hydroprocessing larger hydrocarbon molecules, including molecules such as asphaltenes, which unfortunately leads to unconverted heavy oils and/or oil residues in the process, and incomplete hydroprocessing (including coke formation). To worsen matters, unprocessed asphaltenes (and coke) may also adhere to additive particles, thus preventing their further utility in the process.

"There accordingly remains a need for a process for hydroprocessing heavy oils and oil residues such as vacuum gas oil, atmospheric residue and vacuum residue into substances having smaller molecules of greater utility that simultaneously offers the cost benefits of avoiding metal catalysts alongside improved process efficiency, especially when it comes to hydrocracking asphaltenes."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Surprisingly, the applicants have now found that the above problems may be addressed by providing a process for the hydroprocessing of heavy oils and/or oil residues, the process comprising the steps of contacting a non-metallised carbonaceous material with an acid to form a non-metallised carbonaceous additive; and contacting the heavy oils and/or oil residues with the non-metallised carbonaceous additive in the presence of a hydrogen-containing gas at a temperature of from 250.degree. C. to 600.degree. C. Also surprisingly, the applicants have found that the above problems may be addressed with a non-metallised carbonaceous additive for the hydroprocessing of heavy oils and/or oil residues wherein the non-metallised carbonaceous additive comprises an acid-treated, non-metallised carbonaceous material."

For additional information on this patent application, see: Schleiffer, Andreas; Yang, Hong. Process for Hydrocracking Heavy Oil and Oil Residue with a Carbonaceouse Additive. Filed February 12, 2015 and posted September 28, 2017.
