Abstract: A method for forming mesophase pitch can include applying a stimulus to a first amount of coal tar to form a first amount of mesophase pitch. The stimulus can include one or more of an electromagnetic field (“EMF”) or a magnetic field. The method can further include evaluating a characteristic of the first amount of mesophase pitch, changing a parameter of the stimulus in response to evaluating the characteristic of the first amount of mesophase pitch, and applying the stimulus exhibiting the changed parameters to a second amount of coal tar to form mesophase pitch.

Abstract: A delayed thermal cracking process, system, and apparatus for heavy (i.e., high boiling point) coker feed materials which eliminates the production of a solid coke product and replaces the coke product with a higher value, pumpable tar liquid material which can be used as an asphalt paving material, as a fuel oil, or for other purposes. A hydrocarbon cooling and diluting material is added to and mixed with the tar material in the coking drum after the fill cycle to produce the liquid tar product and eliminate the steam-out, quenching, draining, unheading, hydraulic cutting, reheading, pressure testing, and warm-up procedures previously required in delayed coking systems, and to also eliminate the environmental issues and costs associated therewith.

Abstract: A method is disclosed for preparing an aviation fuel composition by subjecting a feedstock of biological and/or recycled origin to cracking in a cracking unit and to fractionation in a fractionation unit to obtain a kerosene fraction. The obtained kerosene fraction is subjected to hydrotreatment in a hydrotreatment unit to form a first jet fuel component. The formed first jet fuel component is mixed with a further jet fuel component to form a fuel composition having a wear scar diameter of 0.78 mm or less, as measured with BOCLE lubricity test method according to ASTM D5001. The feedstock contains one or more of tall oil pitch (TOP), a mixture of sludge palm oil, palm fatty acid distillate and animal fat (FATS), and used lubricant oil (ULO).

Abstract: Processes and systems for the conversion of hydrocarbons herein may include separating an effluent from a moving bed reactor, the effluent including reaction product, first particulate catalyst, and second particulate catalyst. The separating may recover a first stream including the reaction product and first particulate catalyst and a second stream including second particulate catalyst. The second stream may be admixed with a regenerated catalyst stream including both first and second particulate catalyst at an elevated temperature. The admixing may produce a mixed catalyst at a relatively uniform temperature less than the elevated regenerated catalyst temperature, where the temperature is more advantageous for contacting light naphtha and heavy naphtha within the moving bed reactor to produce the effluent including the reaction product, the first particulate catalyst, and the second particulate catalyst.

Abstract: Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

Abstract: The present disclosure describes a fractional distillation tower that uses color sensing technology that provides nearly real time cutpoint analysis of high value products. With this information, the cutpoints may be aggressively shifted to a financially advantageous product slate and stay aggressive throughout each day rather than wait for a once or twice daily report of what products have been made and their analyses with respect to specifications.
