Patent ID: 10906804

Abstract:
Systems and methods for hydrogen generation via ammonia decomposition that utilize a fixed bed reactor configured to receive inflows of NH3 and oxidant and to produce an outflow of high purity H2. The fixed bed reactor contains a fixed bed of a NH3 decomposition catalyst wherewith the NH3 decomposes to form N2 and H2; a plurality of ceramic hollows fibers with a high surface to volume ratio disposed in the fixed bed, the hollow fibers having an H2 selective membrane disposed thereon for extracting H2 from N2 and to form a permeate of the high purity H2 and a retentate of primarily N2; and a catalytic H2 burner also disposed in the fixed bed, the catalytic H2 burner for burning a portion of the H2 with the oxidant to provide thermal energy for the NH3 decomposition.
