Title:
SYSTEMS AND METHODS FOR HIGH EFFICIENCY REGENERATIVE SELECTIVE CAYALYTIC REDUCTION
Document Type and Number:
WIPO Patent Application WO/2012/012268
Kind Code:
A3
Abstract:
The invention provides a system for regenerative selective catalytic reduction including a catalyst chamber that contains a catalyst for reducing ΝΟχ in a gas stream passing therethrough. The system also includes a reactant injector, first and second heat exchangers, and a valve manifold adapted to direct a substantially continuous gas stream through the heat exchangers and catalyst chamber in such a manner as to flow through the catalyst chamber in the same flow direction during each cycle of the system. The invention also provides a process of regenerative selective catalytic reduction wherein the gas stream through the catalyst chamber flows in the same flow direction during each cycle of the process.
