Benefits of technology

The present invention provides a method of liquefaction and fuel production that has various technical advantages over other methods. It can adjust the ratio of carbonaceous material and biomass to produce a desired mixture of products. It can produce a fully or substantially synthetic fuel that meets specific specifications and can also produce a synthetic kerosene-dominant refinery. However, it has a smaller carbon footprint than other methods of liquefaction and fuel production. It can also be integrated with existing fuel production facilities, allowing for the production of desired fuel without the need for additional blendstocks. It can refine fuel precursors into a desired fuel in a more efficient way than other refining techniques and can accommodate different refining technology preferences. It is flexible and can produce aviation fuels or other transportation fuels. It can also reduce the size of the plant and eliminate the need for substantial gas cleanup equipment.

Problems solved by technology

However, petroleum is a limited and nonrenewable resource, and the extraction, transportation, and refining of petroleum can be problematic from an environmental, political, and energy efficiency standpoint.
In addition, most competitive technologies do not produce all of the key constituents needed to produce synthetic fuels, such as aviation fuels.

example 1

Production of Solvent

[0111]Initial tests were performed to produce test coal-derived solvent for the liquefaction runs. A slurry including coal tar-derived solvent (b.p., 343°-538° C.) was formed with predried pulverized coal. The slurry was contacted with a commercial presulfided CoMo catalyst under a hydrogen pressure in the autoclave. The experiment was run at 450° C., a pressure of 78 atmo, and under a constant flow of 13 scfh hydrogen for 60 minutes. The product slurry was distilled to produce test coal-derived solvent (b.p., 343°-538° C.). The liquefaction procedure was repeated using the solvent generated to produce solvent using a recycled solvent.

Runs 1-3: Liquefaction of Canola Oil and Coal

[0112]After a desired quantity of the test coal-derived solvent was generated using the recycled solvent, a slurry including coal, canola oil, vacuum bottoms (e.g., hydrocarbon waxes similar to petroleum residue left after refining of crude oil) and coal-derived solvent (having a mass ratio of 0.8:0.2:1.0:1.0), and 0.03 wt % of commercial presulfided CoMo catalyst was placed in the autoclave. The sulfur in the coal was enough to keep the catalyst sulfided during the run. The reactor was charged with 70 atm hydrogen pressure and placed in the heating jacket. The reactor was heated to 350° C. to convert triglycerides into paraffins via hydrolysis and decarbonylation and then heated and pressurized to the temperature and pressure shown in Table 1, which also shows other operating conditions. A constant hydrogen flow was maintained throughout the run. The runs were carried out in hydrogen flow-through mode (13.18 scfh). At the end of the run,...

Runs 4-5: Liquefaction of Algae Oil and Coal

[0114]Coal, algae oil, and catalyst were slurried in a coal-derived solvent. A similar procedure to that used in Example 2 was used. Operating conditions and yield data are given in Tables 1 and 2.

Abstract

The present invention relates to production of fuels from carbonaceous material and biomass. In some examples, the carbonaceous material is nonpetroleum fossil fuel or petroleum residuals. Various embodiments of the present invention provide a method of liquefaction of carbonaceous material and biomass. The method includes providing or obtaining a feed mixture, the mixture including carbonaceous material and biomass. The method also includes subjecting the feed mixture to liquefaction, to provide a product slurry. Various embodiments of the present invention provide a method of fuel production from carbonaceous material and biomass. The method includes separating the product slurry from the liquefaction, to give a conversion component. The method also includes processing the conversion component, to give a fuel.
