Ọgbọ hydrogen

  • Ammonia Decomposition to Hydrogen

    Amonia Decomposition

    Mmepụta hydrogen nke ire ere amonia na-ewere amonia mmiri mmiri dị ka akụrụngwa. Mgbe vaporization gasịrị, a na-enweta gas agwakọta nwere 75% hydrogen na 25% nitrogen site na kpo oku na ire ere na ihe na-akpata. Site na mgbasawanye nrụgide nrụgide, enwere ike imepụta hydrogen nwere ịdị ọcha 99.999%.

  • Methanol Decomposition to Hydrogen

    Methanol mebiri emebi na hydrogen

    Methanol ire ere

    N'okpuru ụfọdụ okpomọkụ na nrụgide, methanol na uzuoku na-enweta mmeghachi omume mgbawa methanol yana mmeghachi omume ngbanwe carbon monoxide iji mepụta hydrogen na carbon dioxide na ihe mkpali. Nke a bụ usoro mmeghachi omume catalytic siri ike nke nwere ọtụtụ ihe na ọtụtụ mmeghachi omume, yana nha kemịkalụ bụ nke a:

    CH3OH → CO +2H2(1)

    H2O+CO → CO2 +H2(2)

    CH3OH +H2O → CO2 +3H2(3)

    A na-ekewa hydrogen na carbon dioxide nke emepụtara site na mmeghachi omume ngbanwe site na nrụgide swing adsorption (PSA) iji nweta hydrogen dị oke ọcha.
