Upgrading diene-containing light olefins in a fluidized bed reactor
This patent describes a continuous system for catalytic conversion of diolefinrich hydrocarbon feedstock to heavier hydrocarbons under essentially isothermal conditions at elevated temperature, comprising in combination: enclosed vertical reactor means without baffles containing a fluidized bed of solid conversion catalyst particles in turbulent flow regime; heat exchange means in the reactor for controlling reaction zone temperature; particle separator means contained within the reactor for separation of catalyst particles and product effluent; bottom inlet means for receiving a fluidizing hydrocarbon vapor stream and passing the hydrocarbon vapor stream upwardly through the catalyst bed to maintain turbulent fluidized bed catalyst flow; grid means for distributing the fluidizing hydrocarbon vapor stream above the bottom inlet means; liquid pump means for pressure injecting an atomized stream of cold liquid feedback deep into the reaction zone; thermally insulated conduit means connected to the liquid pump for transporting the stream of liquid feedstock into the reaction zone above the grid means at a temperature below reaction zone temperature; thermally insulated atomizing nozzle means for atomizing the stream of liquid feedstock connected to the conduit means to provide an atomized feedstock stream with an average particle size not greater than 300 microns; catalyst regenerator means operatively connected to the vertical reactor means for regenerating spent catalyst particles for recycle to the reactor.
