    摘要: An FCC process comprising an enlarged riser section and a distributor in an elevated position and with an opening in its tip away from riser walls may reduce coke build-up along the interior walls of a riser. Catalytic mixing may be improved, which could reduce riser coking by increasing hydrocarbon contact with catalyst before contacting the riser wall. Increasing the distance between the introduction of the hydrocarbon and the riser wall may increase this likelihood for hydrocarbon-catalyst contact. Highly contaminated hydrocarbons cause greater coking than do normal hydrocarbons and this FCC process may be effective in decreasing riser coking on such heavy hydrocarbons.

    摘要: A process for improving the yield of ethylene and propylene from a light naphtha feedstock includes obtaining light naphtha feedstock from a primary cracking zone having a cracking catalyst. The light naphtha feedstock is contacted with an olefin catalyst in an olefin producing zone to produce an ethylene- and propylene-rich stream. After reacting with the olefin catalyst, the ethylene- and propylene-rich stream is separated from the olefin catalyst from in a separator zone. At least a portion of the olefin catalyst is regenerated by combusting coke deposited on a surface of the olefin catalyst in an oxygen-containing environment, and at least a portion of the olefin catalyst is heated. These portions could be the same one or they could be different. In some embodiments, at least a portion of the olefin catalyst could be neither regenerated nor heated. The olefin catalyst is returned to the olefin producing zone.
