Abstract:
A method and apparatus for removing nitrogen oxides from gas streams, includes introducing a to-be treated gas stream into a gas-solid reaction column, and introducing ferric chloride solid particles into the gas-solid reaction tower at the same time. The nitrogen oxides in the gas streams undergo gas-solid chemical adsorption reaction with the ferric chloride solid particles to form solid products and are removed, and thereby purifying the gas.

Claim (Index 7):
A method according to  claim 1 , wherein said nitrogen oxides comprise nitrogen oxide and nitrogen dioxide.
