Systems and methods to remove liquid product and fines from a slurry reactor

摘要

The present invention provides methods and means for separating slurry liquid from catalyst in a three-phase slurry process. The embodiments of the invention are characterized by conducting the three-phase process under conditions to provide an upper region in the slurry that contains a catalyst concentration of about 20 wt% or less and a lower region with a catalyst concentration higher than about 20 wt%. A portion of the slurry in this upper region is degassed and passed to liquid-solid separation devices for recovery of liquid product.
