Hydrogen generation device

special materials

  • Special program control valves

    Special program control valves

    Special program control valves independently researched and developed and produced by Techairs uses the world’s advanced low-flow resistance valve body, with the streamlined runner and anti-erosion and anti-fatigue technology, switch of the valve is fast with good sealing performance, and no leakage of the switch reaches more than 1 million times, and it has the capacity to bear two-way pressure and resist high-speed airflow.
  • Efficient adsorbents

    Efficient adsorbents

    Adsorbent directly affects the efficiency and service life of the device. Possible impurities are CO, CO2, H2O, and because CO will poison the majority of hydrogenation catalysts, in order to strictly control the content of impurities in hydrogen, quality control shall be conducted on the adsorption capacity of the adsorbent, bulk density, mechanical strength, separation ratio and so on. Use TechairsTM efficient adsorbent jointly produced by Techairs, such as AC12-1P, AZ51-2L, AZ91-2T, especially the efficient adsorbent that can absorb CO. Its advantages and features are as follows: * Large adsorption capacity for adsorbate other than hydrogen - reduce the volume of filling and investment; * Good adsorption performance for very low concentration of impurities; * Can produce ultra-pure hydrogen that results in large separation factor for adsorbate and hydrogen - improve the separation effect and increase yield; * Have sufficient mechanical strength and wear resistance - its service life can reach up to more than 15 years;
  • Catalysts


    The self-developed bi-functional hydrogen catalysts allow the synchronization of reforming and switch, which are featured with big specific surface area, suitable pore distribution, high conversion rate, good selectivity, high antitoxic and heat resistance. Compared to the other similar products, the comprehensive performance is increased by 20% to 30%.
