Upgrading light olefin fuel gas and catalytic reformate in a turbulent fluidized bed catalyst reactor
A fluidized bed catalyst process is described for conversion of C/sub 4/- light olefinic gas feedstock to C/sub 5/+ hydrocarbons and for conversion of C/sub 6/ to C/sub 8/ aromatic feedstock to C/sub 7/ to C/sub 11/ aromatics. It consists of: maintaining a fluidized bed of zeolite catalyst particles in a turbulent reactor bed at a temperature of about 500/sup 0/ to 800/sup 0/F, the catalyst having an apparent particle density of about 0.9 to 1.6 g/cm/sup 3/ and a size range of about 1 to 150 microns, an average catalyst particle size of about 20 to 100 microns containing about 10 to 25 weight percent of fine particles having a particle size less than 32 microns; contacting the feedstocks and passing the feedstocks upwardly through the fluidized catalyst bed under turbulent flow conditions at reaction conditions sufficient to convert at least about 70% of the olefin feedstock and to convert at least 5% of the C/sub 6/ to C/sub 8/ aromatic feedstock; maintaining turbulent fluidized bed conditions through the reactor bed between transition velocity and transport velocity at a superficial fluid velocity of about 0.3 to 2 meters per second; and recovering hydrocarbon product containing C/sub 5/+ hydrocarbons C/sub 7/ to C/sub 11/ aromatic hydrocarbons.
