E-huela, he aha ia?
I ka pōkole, e-fuel - heluhelu: ʻoluʻolu kaiapuni - ʻokoʻa i kāna mau hoa kuʻuna ma ke ʻano o ka hana ʻana. Hoʻopili ka mea hope i kahi ʻano hana synthetic me ka hoʻohana ʻana i ka wai a me carbon dioxide, a me ka hoʻohana ʻana i ka uila ʻōmaʻomaʻo a me ka ikehu lā. E like me nā wahie mōʻalihaku kaulana, ma waena o nā wahie synthetic hiki iā mākou ke loaʻa i ka e-gasoline, e-diesel a me e-gasoline.
Kūleʻa, he aha ia manaʻo?
ʻO ka pinepine, kapa ʻia nā wahie synthetic pili i ka honua. He aha ia mea? Hoʻokumu ʻia ka huaʻōlelo ma ko lākou pilina me carbon dioxide. ʻO ke kūʻokoʻa i ʻōlelo ʻia ma luna nei, ʻo ia ka carbon dioxide i mea e pono ai e hana i ka e-fuel a me kahi huahana o kona puhi ʻana. Nui no ka manaʻo. Eia nō naʻe, ma ka hoʻomaʻamaʻa ʻana, ʻo ia ka carbon dioxide e komo i ka lewa me nā kinoea hoʻopau. Ke hoʻopaʻapaʻa nei ka poʻe makemake i ke kaiapuni i nā wahie hou e ʻoi aku ka maʻemaʻe o kēia mau mea ma mua o nā kinoea hoʻopau mai nā ʻenekini e holo ana ma nā wahie mōʻalihaku kahiko.
ʻAʻole i loaʻa i ka sulfur a me benzene
No laila, e hoʻomaka kākou me ka wahie i hoʻohana pinepine ʻia - ka ʻaila. ʻO kāna analogue synthetic he e-gasoline. ʻAʻole koi ʻia ka aila maʻemaʻe e hana i kēia wahie pili i ke kaiapuni, no ka mea ua hoʻololi ʻia e isooctane ma ke ʻano wai. Hoʻopuka ʻia ka mea hope mai kahi pūhui kemika organik mai kahi hui hydrocarbons i kapa ʻia ʻo isobutylene a me ka hydrogen. ʻO ka E-gasoline ka mea i hōʻike ʻia e kahi helu octane kiʻekiʻe loa ROZ (Research Oktan Zahl - ka mea i kapa ʻia ʻo ka helu octane noiʻi), hiki i 100. No ka hoʻohālikelike ʻana, ʻo ka helu octane o ka ʻaila i loaʻa mai ka ʻaila ʻaila mai 91-98. ʻO ka maikaʻi o ka e-gasoline ka maʻemaʻe - ʻaʻole i loko o ka sulfur a me benzene. No laila, maʻemaʻe loa ke kaʻina hana hoʻopau, a ʻo ka helu octane kiʻekiʻe e alakaʻi i ka piʻi nui ʻana i ka lākiō hoʻopiʻi, kahi e alakaʻi ai i ka hoʻonui ʻana i ka pono o nā mīkini ʻaila.
Blue Crude - aneane uila uila
ʻAʻole like me ka wahie diesel maʻamau, hoʻohana ʻia ka diesel uila ma ke ʻano he wahie synthetic. ʻO ka mea e mahalo ai, no ka hana ʻana, pono ʻoe i nā mea ʻaʻole pili i ka hana ʻana i nā ʻāpana diesel, e like me ka wai, carbon dioxide a me ka uila. No laila pehea e hana ʻia ai ka e-diesel? ʻO ka mea mua o nā mea i luna, ka wai, ua wela i kahi mahana o kahi 800 degere C i ka wā o ka electrolysis. Hoʻololi ia i mahu, hoʻoheheʻe ia i hydrogen a me ka oxygen. ʻO ka hydrogen i loko o ka synthesis reactors a laila hana me ka carbon dioxide i nā kaʻina hana kemika. Hana ʻia nā mea ʻelua ma kahi mahana o 220 ° C a me kahi kaomi o 25 bar. Ma ke ʻano o nā kaʻina hana synthesis, loaʻa kahi wai ikehu i kapa ʻia ʻo Blue Crude, ʻo ia ka mea i hoʻokumu ʻia i nā pūhui hydrocarbon. Ma hope o ka pau ʻana, hiki ke kamaʻilio e pili ana i ka wahie e-diesel synthetic. He helu cetane kiʻekiʻe kēia wahie a ʻaʻole i loaʻa nā pūhui sulfur pōʻino.
Me ka methane synthetic
A ʻo ka mea hope loa, he mea no ka poʻe aloha i ke kinoea kaʻa, akā ʻaʻole i ka mana kaulana loa o LPG, ʻo ia ka hui ʻana o propane a me ka butane, akā i loko o ke kinoea CNG maoli. ʻO ke kolu o ke ʻano wahie kaiapuni, e-gas, ʻaʻohe mea like me ka mea e hoʻokele ai i nā mīkini kaʻa ma hope o nā hoʻololi ʻenehana. No ka hana ʻana i kēia ʻano wahie pono ʻoe i ka wai maʻamau a me ka uila. I ke kaʻina hana electrolysis, hoʻokaʻawale ka wai i ka oxygen a me ka hydrogen. ʻO ka mea hope wale nō e pono ai no nā kumu hou aʻe. Hoʻopili ka hydrogen me ka carbon dioxide. ʻO kēia kaʻina hana, i kapa ʻia ʻo methanation, e hana i kahi ʻano kemika o ke kinoea electron e like me ke kinoea maoli. He mea nui ia e hoʻomaopopo i kāna unuhi ʻana he mau mea ʻino ʻole e like me ka oxygen a me ka wai.
