  • Publication number: 20240068132
    Abstract: Nucleation enhancement and/or growth rate improvement of mesophase in pitch compositions derived from hydrocarbon feedstocks can be achieved by: reacting in a reaction zone a blend comprising an isotropic feed and a seeding agent, to produce a reacted pitch having a mesophase content of about 10 vol % to 100 vol %, based on the total volume of the reacted pitch, and a softening point (Tsp) below 400° C.; wherein the seeding agent is about 50 wt % or less, based on the total weight of the blend; wherein the seeding agent has a mesophase content of about 0.01 vol % to 100 vol %, based on the total volume of the seeding agent.

  • Patent number: 6260587
    Abstract: A collection and disposal system for intercepting fuel vapor, liquid fuel, and water accumulating at the filler neck compartment of a motor vehicle. The system includes a suction fan, a plurality of conduits communicating between the filler neck compartment and the suction fan, a collector for liquids accumulating in the filler neck compartment, and an electrical control system. The control system includes a switch which operates the suction fan when the filler neck compartment door is open. The suction fan draws vapors from the filler neck compartment through the conduits for disposal. Vapors may be conducted to the emissions control system, in particular the charcoal canister for trapping vapors, a suitable point of the engine such as the intake manifold, carburetor, or throttle body, or may be vented to the open atmosphere. The collector of liquids has a flapper valve which discharges liquids when a predetermined volume is collected. A buzzer is arranged to annunciate operation of the suction fan.
