PROCESS FOR UPGRADING LIGHT OLEFINS IN A TURBULENT FLUIDIZED CATALYST BED REACTOR ABSTRACT A fluidized bed catalytic process for conversion of light olefinic gas feedstock containing ethene to produce hydrocarbons rich in C5+ liquids, comprising the steps of maintaining a fluidized bed of zeolite catalyst particles in a turbulent reactor bed at a temperature of about 315 to 510°C, said catalyst having an apparent particle density of about 0.9 to 1.6 g/cm3 and a size range of about 1 to 150 microns, and 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; passing hot feedstock vapor upwardly through the fluidized catalyst bed under turbulent flow conditions; 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 a major amount of C5+ hydrocarbons and containing C3-C5 alkanes and alkenes in the ratio of about 0.2:1 to 5:1.
