摘要： 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.

摘要： This invention relates to a process and system for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) subjecting a vacuum resid to a first thermal conversion in a thermal conversion reactor (such as delayed coker, fluid coker, Flexicoker™, visbreaker and catalytic hydrovisbreaker) where at least 30 wt % of the vacuum resid is converted to material boiling below 1050° F. (566° C.); (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being integrated into a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to the radiant furnace in said steam cracking furnace; and (d) recovering at least 30 wt % olefins from the material exiting the radiant furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).

摘要： The invention relates to a regenerative reactor system which includes a reverse flow regenerative reactor. The reverse flow regenerative reactor includes a housing enclosing an interior region, and process flow components configured to manage the flow of a pyrolysis stream through the interior region. The process flow components include reactor beds. The reverse flow regenerative reactor also includes a pyrolysis inlet conduit for managing flow of the pyrolysis stream to the reverse flow regenerative reactor, and further includes a liquid distribution device that is configured to disperse a liquid portion of the pyrolysis stream along an internal surface of the pyrolysis inlet conduit.
