Patent ID: 8388920

Claim:
A method for supplying NH 3 to an exhaust gas treatment system comprising: producing ammonia by an electrolytic hydrolysis of urea effected by applying a voltage difference to an electrolytic cell comprising: a cathode having a first conducting component, an anode having a second conducting component, urea, and an alkaline electrolyte composition in electrical communication with the anode and the cathode, where the alkaline electrolyte composition has a hydroxide concentration of at least 0.01 M or a pH of at least 8, wherein the voltage difference is applied across the cathode and the anode, wherein the voltage difference is sufficient to effect the electrolytic hydrolysis of urea to produce at least NH 3 ; recovering at least a portion of the NH 3 ; and transferring the at least a portion of the NH 3 to the exhaust gas treatment system.
