Title: Spouted bed with venturi draft tube and method for improved gas-solid contacting

Abstract

A Venturi draft tube spouted bed and method are disclosed that enables scale-up with small particles and improves heat and mass transfer by increasing material turnover rate. A Venturi-style eductor has been incorporated into the spouted bed draft tube to provide suction at the bottom of the bed to better entrain material and reduce the propensity for dead zones at the bottom of the narrow conical section.
