Title: Arie Jacobus Kalkman: Innovator in Hydrogen Purification and Energy Storage
Introduction
Arie Jacobus Kalkman is a notable inventor based in Zwijndrecht, Netherlands. He has made significant contributions to the fields of hydrogen purification and energy storage, holding a total of 2 patents.
Latest Patents
Kalkman's latest patents include a process for wet oxidation hydrogen purification. This invention focuses on purifying a raw hydrogen gas stream that contains hydrogen gas in an amount of 85-99%. The process involves contacting the raw hydrogen gas stream with an oxidized bed made of oxidized metal, resulting in a waste gas stream that comprises water and less than 5% hydrogen gas. This process also leads to a reduction of the oxidized metal. Additionally, the invention includes a step where a bed containing reduced metal is contacted with water to produce a purified hydrogen gas stream with over 99% hydrogen gas, preferably 99.97% or more. Furthermore, Kalkman has developed an internal configuration for redox-based heat storage systems. This invention consists of a chemical combustion reactor that includes at least two porous active fixed beds separated by an inactive insulating layer, which are partially surrounded by an insulating mantle. The active beds consist of a metal and/or its oxide.
