Abstract
The invention reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. This provides an increased exit cross-sectional area for the upper reduction gas to escape and reduce the overall exit velocity of the combined upper and lower reduction gases and reduces the potential for catalyst fluidization.
Claims11
A reduction vessel having a reduction zone comprising an upper zone and a lower zone wherein said upper zone comprises an annular shaped baffle and an annular shaped opening and wherein a portion of said annular shaped baffle adjacent to said opening is a ventilated section.
An apparatus to increase a flow of gas exiting a reaction vessel comprising a cylindrical shaped reactor wherein within said cylindrical shaped reactor is positioned at least one annular baffle wherein a portion of a surface of said annular baffle comprises a screen.
