Wahi a ka ʻikepili noiʻi ʻoihana,hana kinoea hydrogenKe noho nei ke kaʻina hana i ka wahi mua ma ka mākeke hana hydrogen honua.ʻO ka hapa o ka hana hydrogen mai ke kinoea kūlohelohe ma Kina ka lua, ma hope o ka lanahu.Hoʻomaka ka hana ʻana o ka hydrogen mai ke kinoea kūlohelohe ma Kina i ka makahiki 1970, e hāʻawi nui ana i ka hydrogen no ka synthesis ammonia.Me ka hoʻomaikaʻi ʻana i ka maikaʻi catalyst, kahe kaʻina hana, pae kaohi, ʻano mea hana a me ka hoʻolālā ʻana, ua hōʻoia ʻia ka hilinaʻi a me ka palekana o ke kaʻina hana hydrogen gas maoli.
ʻO ke kaʻina hana hydrogen kinoea maoli he ʻehā mau ʻanuʻu: ka hoʻomaʻamaʻa mua ʻana i ke kinoea, ka hoʻoponopono ʻana i ka mahu kinoea maoli, ka hoʻololi ʻana o carbon monoxide,hoʻomaʻemaʻe hydrogen.
ʻO ka hana mua ʻo ka pretreatment maka, ka mea nui e pili ana i ka desulfurization kinoea, ʻo ka hana maoli ka hoʻohana ʻana i ka cobalt molybdenum hydrogenation series zinc oxide ma ke ʻano he desulfurizer e hoʻololi i ka sulfur organik i loko o ke kinoea kūlohelohe i ka sulfur inorganic a laila wehe.
ʻO ka hana ʻelua, ʻo ia ka hoʻololi ʻana i ka mahu o ke kinoea maoli, kahi e hoʻohana ai i ka nickel catalyst i ka reformer e hoʻohuli i nā alkanes i loko o ke kinoea maoli i loko o ke kinoea feedstock nona nā mea nui he carbon monoxide a me ka hydrogen.
ʻO ke kolu o ka ʻanuʻu ʻo ia ka hoʻololi ʻana o carbon monoxide.Hoʻopili ʻo ia me ka mahu wai i mua o kahi catalyst, a laila e hoʻohua ai i ka hydrogen a me carbon dioxide, a loaʻa i kahi kinoea hoʻololi i haku ʻia me ka hydrogen a me carbon dioxide.
ʻO ka hana hope e hoʻomaʻemaʻe i ka hydrogen, i kēia manawa ʻo ka ʻōnaehana hoʻomaʻemaʻe hydrogen i hoʻohana pinepine ʻia ʻo ia ka ʻōnaehana hoʻomaʻemaʻe hoʻomaʻemaʻe ʻana i ka kaomi swing adsorption (PSA).Aia kēia ʻōnaehana i nā ʻano o ka hoʻohana ʻana i ka ikehu haʻahaʻa, ka hana maʻalahi a me ka maʻemaʻe kiʻekiʻe o ka hydrogen.
ʻO ka hana ʻana o ka hydrogen mai ke kinoea kūlohelohe nā mea maikaʻi o ka nui o ka hydrogen production scale a me ka ʻenehana makua, a ʻo ia ke kumu nui o ka hydrogen i kēia manawa.ʻOiai ʻo ke kinoea maoli he wahie fossil a hoʻopuka i nā kinoea ʻōmaʻomaʻo i ka hana ʻana i ka hydrogen uliuli, akā ma muli o ka hoʻohana ʻana i nā ʻenehana holomua e like me ka hopu kalapona, hoʻohana a me ka mālama ʻana (CCUS), ua hōʻemi ia i ka hopena o ka honua ma o ka hopu ʻana. nā kinoea ʻōmaʻomaʻo a me ka loaʻa ʻana o ka hana haʻahaʻa haʻahaʻa.
