Method and Apparatus for Managing the Conversion of Hydrocarbons Into Olefins

摘要

An apparatus and method are provided for processing hydrocarbon feeds. The method enhances the conversion of hydrocarbon feeds into ethylene. In particular, the present techniques expose feed containing hydrocarbons to high-severity operating conditions in a pyrolysis reactor and separate the reactor product from the reactor into a first product having hydrogen and a second product including ≧90 mole percent of the acetylene in the reactor product. Then, the second product is reacted with a catalyst in a converter to form ethylene.

1. A hydrocarbon conversion method comprising:
exposing a pyrolysis feed under thermal pyrolysis high-severity operating conditions to produce a reactor product comprising hydrogen, ethylene, and X mole % acetylene per mole of reactor product; reacting at least a portion of the reactor product with a catalyst in a converter operated in at least partially in the vapor phase to form a conversion product comprising 0.0 mole % to Z mole % acetylene per mole of the conversion product, the portion of the reactor product comprising Y mole % of acetylene per mole of the portion of the reactor product and the portion of the reactor product having a hydrogen to acetylene molar ratio in the range of from 1.0 and 10.0; and wherein (i) X<90.0% of a first acetylene non-autodecomposition amount, (ii) Y<90.0% of a second acetylene non-autodecomposition amount, and (iii) Y>Z.
