A quartz liner is installed inside the reactor to provide electrical insulation between the catalyst and the reactor wall. The gap between the liner and the reactor is meticulously calculated and sealed at one end, creating a dead volume between the glass liner and the inner wall of the reactor. The reactor’s material inlet extends into the liner, minimizing the risk of gas entering the space between the liner and the reactor’s inner wall. The electrodes are rated for 2000 V.

Nitrification Cascade Reactor System
