摘要： Processes and systems for upgrading a hydrocarbon-containing feed. The hydrocarbon containing feed and a plurality of fluidized particles can be fed into a pyrolysis reaction zone. The plurality of fluidized particles can have a first temperature that can be sufficiently high to enable pyrolysis of at least a portion of the hydrocarbon-containing feed on contacting the particles. The particles can include an oxide of a transition metal element capable of oxidizing molecular hydrogen at the first temperature. The hydrocarbon-containing feed can be contacted with the particles in the pyrolysis reaction zone to effect pyrolysis of at least a portion of the hydrocarbon-containing feed to produce a pyrolysis effluent. At least a portion of the transition metal element in the particles in the pyrolysis effluent can be at a reduced state compared to the transition metal element in the particles fed into the pyrolysis reaction zone.

摘要： Processes and systems for converting a hydrocarbon-containing feed. The feed and heated particles can be contacted within a pyrolysis zone to effect pyrolysis of at least a portion of the feed to produce a pyrolysis zone effluent and a first gaseous stream rich in olefins and a first particle stream rich in the particles can be obtained therefrom. At least a portion of the first particle stream, an oxidant, and steam can be fed into a gasification zone and contacted therein to effect gasification of at least a portion of coke disposed on the surface of the particles to produce a gasification zone effluent. A second gaseous stream rich in a synthesis gas and a second particle stream rich in heated and regenerated particles can be obtained from the gasification zone effluent. At least a portion of the second particle stream can be fed into the pyrolysis zone.
