ʻO nā huahana e lawelawe ana i nā pono olakino o ka lehulehu.Wahi a WHO, pono e loaʻa kēia mau huahana "i nā manawa a pau, i ka nui kūpono, i nā ʻano dosage kūpono, me ka maikaʻi a me ka ʻike kūpono, a ma ke kumukūʻai hiki i ke kanaka a me ke kaiāulu ke loaʻa".

  • ʻO ka hoʻoheheʻe ʻana i ka Ammonia i ka hydrogen

    ʻO ka hoʻoheheʻe ʻana i ka Ammonia i ka hydrogen

    ʻAmonia Decomposition

    ʻO ka hana hydrogen o ka hoʻoheheʻe amonia e lawe i ka ammonia wai ma ke ʻano he mea maka.Ma hope o ka vaporization, loaʻa ke kinoea hui pū me 75% hydrogen a me 25% nitrogen ma ka hoʻomehana a me ka decomposition me ka catalyst.Ma o ke kaomi swing adsorption, hiki ke hana hou ʻia ka hydrogen me 99.999% maʻemaʻe.

  • Hoʻoheheʻe ʻia ka Methanol i ka hydrogen

    Hoʻoheheʻe ʻia ka Methanol i ka hydrogen

    Hoʻoheheʻe Methanol

    Ma lalo o kekahi mahana a me ka puʻe, e loaʻa ka methanol a me ka mahu i ka methanol cracking reaction a me ka hoʻololi kalapona monoxide e hoʻohua i ka hydrogen a me ke kalapona kalapona me ka catalyst.He pūnaehana hoʻoheheʻe catalytic hoʻoheheʻe nui kēia, a penei ka hoʻohālikelike kemika:

    CH3OH → CO +2H2(1)

    H2O+CO → CO2 +H2(2)

    CH3OH +H2O → CO2 +3H2(3)

    Hoʻokaʻawale ʻia ka hydrogen a me carbon dioxide i hana ʻia e ka reforming reaction e ka pressure swing adsorption (PSA) no ka loaʻa ʻana o ka hydrogen maʻemaʻe kiʻekiʻe.
