ABSTRACT:
A catalytic converter system for engine exhaust gases provides an auxiliary moving bed of SO.sub.2 adsorption material such that the SO.sub.2 content of the exhaust stream can be continuously adsorbed into a segmental portion of the bed prior to reaching the catalytic conversion zone. At the same time, the higher temperature treated gases from the catalyst zone are continuously passed through another portion of the SO.sub.2 adsorption material to effect the removal of sorbed SO.sub.2 therefrom, and the energy of the exhaust gas stream flow is utilized to contact vanes or turbine type blades to provide the continuous rotational movement of the bed of SO.sub.2 adsorbing material so that it, in turn, is rotated or cycled through the adsorption zone and through the desorption zone and then back to the adsorption zone in a continuous operation as long as there is exhaust gas flow in the system.
