Title: David Alfredo Pacheco Tanaka: Innovator in Hydrogen Separation and Recycling Technologies
Introduction
David Alfredo Pacheco Tanaka is a notable inventor based in San Sebastián, Spain. He has made significant contributions to the field of hydrogen separation and recycling technologies. With a total of 2 patents, his work focuses on innovative processes that enhance the efficiency and sustainability of hydrogen use.
Latest Patents
One of his latest patents is titled "Process for the recovery and recycling of materials that constitute supported palladium membranes." This process involves the separation of the palladium (or palladium alloy) layer from the support by contacting the palladium membrane with hydrogen under pressure and at low temperature. Following this, a second gas, different from hydrogen, is introduced. The separated palladium layer can then be treated to solubilize the palladium and any alloy metals to obtain reusable salts, which can be utilized in the preparation of new palladium membranes. Additionally, the recovered supports are also reusable.
Another significant patent is the "Method for low hydrogen content separation from a natural gas mixture." This method includes several steps, starting with providing a stream containing hydrogen. The hydrogen stream is then transferred to a first membrane unit to obtain a retentate and a permeate, where the molar fraction of hydrogen in the permeate is higher than in the retentate. The retentate is subsequently sent to an electrochemical hydrogen compressor for further separation and purification of hydrogen.
