Process of promoting reactions in a fluidized bed comprising a plurality of catalysts

Patent ·
OSTI ID:6742045
This patent describes a process for promoting chemical reactions in a reaction chamber by passing an aeriform fluid upwardly through a fluidized stratified mass of subdivided small-size solids. These are confined in the chamber from beneath the mass. The said solids are at a temperature suitable for promoting chemical reactions and consist of particles having different physical and catalytic characteristics. The process continues by introducing a volatilizable liquid into one of the layers of said stratified mass above the bottom thereof. This causes the said liquid to completely vaporize in said mass with the vapors forming a combined stream having sufficient velocity to maintain said solids in a fluidized condition in said chamber. The process continues by promoting a chemical reaction in said stream while passing through said chamber in contact with said solids, at least one of the components of said combined stream entering said reaction. The stream contains at least one valuable reaction product which is recovered. The fluidized mass of solids consists of a plurality of different layers with the particles of one layer consists largely of different catalysts from those of an adjacent layer.
