A parallel flow reactor (20) for the selective catalytic reduction of nitrog en oxide in a gas stream includes a shell (21) enclosing an interior space in which is located a plurality of substantially parallel planar catalyst beds (23a-f), each containing a catalyst for the selective conversion of NOx. Deflectors (24a-e) in the spaces between the catalyst beds direct the flow o f gas through the beds. An injector (22) upstream of the catalyst beds introduces a reducing agent such as ammonia into the inlet gas stream. The catalyst bed can include monolith or microengineered catalyst.
