Publication number: 20160024397Abstract: Disclosed is a pyrolysis process that is capable of being with reduced coke and/or tar formation. The process can pyrolyze hydrocarbon feed that contains low- to mid-range levels of non-volatiles. Pyrolysis is carried out with a predetermined amount of the feed being in the liquid phase so as to minimize coke and/or tar formation in the pyrolysis reactor. The pyrolysis feed may also include a diluent, such as molecular hydrogen, that further acts to minimize coke and/or tar formation in the pyrolysis reactor. The amount of diluent in the pyrolysis feed can be adjusted to adjust or control dry point of the hydrocarbon in the pyrolysis feed.Type: ApplicationFiled: October 8, 2015Publication date: January 28, 2016Inventors: Paul F.

Patent number: 8092671Abstract: A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.Type: GrantFiled: December 21, 2009Date of Patent: January 10, 2012Assignee: ExxonMobil Chemical Patents, Inc.Inventors: Robert David Strack, Richard C.
