Process for upgrading light olefins in a turbulent fluidized catalyst bed reactor

Abstract From the Canadian patent

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 …
