Web20 mrt. 2024 · March 20, 2024. Zeochem’s molecular sieves are used in a variety of applications, but the goal is always the same: separating two or more components from each other. This can be done in several different ways, but the most common processes are pressure swing adsorption (PSA) and thermal swing adsorption (TSA). WebHydrogen can be produced using a number of different processes. Thermochemical processes use heat and chemical reactions to release hydrogen from organic materials, such as fossil fuels and biomass, or from materials like water. Water (H 2 O) can also be split into hydrogen (H 2) and oxygen (O 2) using electrolysis or solar energy.
