| titleOfInvention | Upgrading diene-containing light olefins in a fluidized bed reactor |
| abstract | An improved fluidized bed process for upgrading olefinic hydrocarbon feedstock by contacting the feedstock with acidic siliceous zeolite conversion catalyst particles at elevated temperature under exothermic conditions to produce heavier hydrocarbons including gasoline range hydrocarbons. The improvement comprises maintaining a turbulent fluidized bed of catalyst particles by flowing hydrocarbon-containing vapor upwardly through said bed at less than transport velocity; and introducing liquid olefinic feedstock comprising at least one C4-C6 diene component into the fluidized catalyst bed in a lower portion thereof by rapidly atomizing and vaporizing the liquid feedstock, thus converting feedstock to heavier hydrocarbon without substantial thermal diene degradation thereof prior to contacting conversion catalyst particles in the fluidized bed. Reaction severity conditions may be maintained by controlling catalyst acidity, reaction temperature and reactant contact time to produce reaction efluent containing propane and propene in the ratio of about 0.2:1 to 200:1. A predominantly liquid product is recovered containing C4-C9 hydrocarbons rich in olefins and aromatics. |
