RADIAL FLOW GAS PHASE REACTOR AND METHOD FOR REDUCING THE NITROGEN OXIDE CONTENT OF A GAS

摘要

A radial flow gas phase reactor for the selective catalytic reduction of nitrogen oxide in a gas stream includes a shell enclosing an interior space in which is located at least one catalyst bed containing a catalyst for the selective conversion of NOx. A deflector directs the flow of gas radially through the bed. An injector upstream of the catalyst introduces a reducing agent such as ammonia into the inlet gas stream. The catalyst bed can includ e particulate, monolith, or microengineered catalyst.
