Abstract
An improved catalytic converter having a shell, a plurality of horizontal catalyst bed supports upon which catalyst is retained and arranged one bed support above another within the shell, and a plurality of horizontal divider plates, one located between each pair of bed supports; the improvement comprising wherein at least one of the bed supports comprises a first full bed support extending essentially across the diameter of the shell, the full bed support comprising (i) an inner dished plate, centrally and symmetrically disposed within the shell, and (ii) an annular dished plate between the shell and the inner dished plate; a substantially circular gas entry port and a substantially circular gas exit port within the shell in gaseous communication with the first full bed support; and a substantially dished divider plate extending essentially across the diameter of the shell above the first bed support and comprising (i) an inner divider plate, centrally and symmetrically disposed within the shell and (ii) an annular curved divider plate between the shell and the inner divider plate having a raised first arcuate-shaped portion adjacent the shell substantially the circumference of t…
