Methods for producing fuels and solvents substantially free of fatty acids

Номер: US20120316370A1
Автор: David Bressler
Принадлежит: University of Alberta

Described herein are methods for producing fuels and solvents from fatty acid re-extraction sources. In general, the pyrolysis products of fatty acids are extracted in order to remove residual fatty acids and produce very pure hydrocarbon compositions composed of alkanes and alkenes. The fatty acids removed from the extraction step can be further pyrolyzed to produce additional hydrocarbons or, in the alternative, the fatty acids can be isolated and used in other applications. Also disclosed herein are fuels and solvents produced by the methods described herein.

Fuel compositions containing an isomerized component of a single carbon number and methods of preparing the fuel compositions

Номер: US20130109893A1
Автор: Heinz J. Robota, Jhoanna C. Alger
Принадлежит: University of Dayton

Fuel compositions containing an isomerized component of a single carbon number may contain at least 97 wt. %, based on the total weight of the fuel composition, of an isomerized component consisting of aliphatic paraffin isomers all having the formula C n H 2n+2 , where 10≦n≦22 and n has the same value for each aliphatic paraffin isomer in the isomerized component. The fuel compositions have a normal alkane content of less than 10 wt. %, based on the total weight of the fuel composition. Methods for preparing the fuel compositions include hydroisomerizing a normal alkane starting material to form an isomerized mixture and subsequently removing remnant normal alkanes from the isomerized mixture by solvent dewaxing and/or distillation. Some of the fuel compositions may have freezing points at or below −47° C., making them amenable for use a surrogate fuels in the place of JP-8.

Multi-stage fractionation of fcc naphtha with post treatment and recovery of aromatics and gasoline fractions

Номер: US20200109340A1
Автор: Ali H. Alshareef
Принадлежит: Saudi Arabian Oil Co

A stream of cracked naphtha is fractionated into at least four specified fractions defined by their respective boiling point ranges. The lightest fraction, IBP to 50° C., is treated in a selective etherification or alkylation process to reduce its RVP value and increase its RON. The second fraction, 50° C. to 150° C., is selectively hydrogenated to treat and convert the diolefins present and the treated stream is sent directly to the gasoline blending pool since it has the desired RON and low sulfur content. The third, and optionally a fourth fraction, boiling in the range of 50° C. to 180° C., in an embodiment, are utilized for the production of aromatics and the raffinate stream, after aromatic extraction, is sent to the gasoline blending pool. A fraction of this latter stream can optionally be recycled for further cracking to produce additional aromatics and gasoline blending components. The heaviest fraction, 180° C. to MBP, constitutes a relatively small volume and is hydrotreated at high pressure, and one portion of the hydrotreated stream is recycled to the FCC unit for further processing and the remaining hydrotreated portion is sent to the gasoline blending pool.

Reduction of sulfur-containing and nitrogen-containing compounds from hydrocarbon feeds is achieved by first contacting the entire feed with a hydrotreating catalyst in a hydrotreating reaction zone operating under mild conditions to convert the labile organosulfur and organonitrogen compounds. An extraction zone downstream of the hydrotreating reaction zone separates an aromatic-rich fraction that contains a substantial amount of the remaining refractory organosulfur and organonitrogen compounds. The aromatic-lean fraction is substantially free of organosulfur and organonitrogen compounds, since the non-aromatic organosulfur and organonitrogen compounds were the labile organosulfur and organonitrogen compounds which were initially removed by mild hydrotreating. The aromatic-rich fraction is oxidized to convert the refractory organosulfur and organonitrogen compounds to oxidized sulfur-containing and nitrogen-containing hydrocarbon compounds. These oxidized organosulfur and organonitrogen compounds are subsequently removed.

Described is a novel process for fractionating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction and water-soluble organics in an economical and energy efficient manner. Using the concepts of solvents and anti-solvent behaviours to separate the pyrolysis oil, which is an emulsion, a method utilising minimal quantities of solvents and water is proposed, By comparison with the existing methods to isolate the hydrophobic aromatic fraction, there is a volume reduction of greater than 50:1. Additionally, there is a significant time saving over the 24 hours for the accepted method as a solvent, and the anti-solvent system is pontaneous.

Systems and methods are provided for solvent deasphalting of steam cracker tar. The resulting deasphalted oil produced from the steam cracker tar can then be hydroprocessed, such as hydrotreated and/or hydrocracked in a fixed bed reactor. The solvent deasphalting can correspond to a mild or trim deasphalting or can correspond to solvent deasphalting at higher solvent to oil ratios. Performing a trim deasphalting can reduce or minimize the amount of deasphalting residue that is formed as a product from the deasphalting process.
