Latest Patents

One of his latest inventions is a hydrogen-selective membrane. This membrane comprises a tubular porous ceramic support with a palladium metal layer deposited on its inside surface. The thickness of the palladium layer is greater than about 10 µm but typically less than about 20 µm. The hydrogen permeation rate of the membrane exceeds 1.0 moles/m².s at temperatures above 500°C and a transmembrane pressure difference of about 1,500 kPa. Additionally, the hydrogen-to-nitrogen selectivity is greater than 600 at temperatures above 500°C and a transmembrane pressure of about 700 kPa. This innovative membrane allows for the separation of hydrogen from a mixture of gases, which may include ammonia. The method involves heating the gas mixture to temperatures between 400°C and 1000°C before flowing it past the membrane. The ammonia is typically decomposed to yield nitrogen and hydrogen using a catalyst such as nickel, which may be placed inside the tubular ceramic support. The gas mixture can be sourced from industrial processes, such as the exhaust gases from the Integrated Gasification Combined Cycle (IGCC) process.
