Abstract
A fluidized bed catalytic process for conversion of propene-rich light olefinic gas feedstock comprising at least 2 mol % ethene and having a C.sub.3 :C.sub.2 molar ratio of at least about 2:1 to produce hydrocarbons rich in C.sub.4.sup.+ aliphatics and aromatics, comprising maintaining a turbulent fluidized bed in a reactor operating at a moderate pressure in the range from about 400 to 2500 kPa, and temperature of about 315.degree. to 510.degree. C., the catalyst having an apparent particle density of about 0.9 to 1.6 g/cm.sup.3, 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, by passing hot feedstock vapor upwardly through the fluidized catalyst bed at a superficial fluid velocity of about 0.3 to 2 meters per second. Hydrocarbon product is recovered containing a major amount of C.sub.5.sup.+ hydrocarbons and containing C.sub.3 -C.sub.5 alkanes and alkenes in the ratio of about 0.1:1 to 200:1 and preferably at a reaction severity index (R.I.) of about 0.2:1 to 5:1.
