Nā puke moʻolelo laha ʻole ma 2023 (1)

Hoʻohana ʻia ka Rare Earth i ka hoʻomaʻemaʻe ʻana i ka pauku kaʻa ʻaila

Ma ka hopena o 2021, ʻoi aku ka nui o nā kaʻa ma Kina ma mua o 300 miliona, ʻo ia ka nui o nā kaʻa kaʻa ma mua o 90%, ʻo ia ka ʻano kaʻa koʻikoʻi ma Kina. I mea e hoʻoponopono ai i nā mea haumia maʻamau e like me ka nitrogen oxides (NOx), hydrocarbons (HC) a me carbon monoxide (CO) i loko o ka pauku kaʻa ʻaila, ua hoʻomohala ʻia ka "catalyst ʻekolu", kahi ʻenehana hoʻopau kaʻa kaʻa ʻāina ma hope o ka mālama ʻana. , hoʻohana ʻia a hoʻomaikaʻi mau ʻia. E alakaʻi ana ka ʻenehana hou i loko o ka cylinder direct injection (GDI) i ka hoʻokuʻu ʻana i nā mea hoʻohaumia particulate (PM) nui, a ʻo ia hoʻi ke alakaʻi ʻana i ka hana ʻenehana kānana ʻāpana ʻaila (GPF). ʻO ka hoʻokō ʻana i nā ʻenehana i luna aʻe e pili ana i ke komo ʻana o ka waiwai hoʻolālā o Kina - rare earth. Ke nānā mua nei kēia pepa i ka hoʻomohala ʻana o nā ʻenehana hoʻomaʻemaʻe pauku kaʻa kaʻa, a laila nānā i nā ʻano noi kikoʻī a me nā hopena o nā mea honua laha loa (ʻoi aku ka cerium dioxide) i ʻekolu ala catalyst oxygen storage material, catalyst carrier/noble metal stabilizer a me ka ʻaila kaʻa. kānana particulate. Hiki ke ʻike ʻia me ka hoʻomohala ʻana a me ka ʻenehana hou ʻana o nā mea hou o ka honua laha ʻole, ʻoi aku ka maikaʻi o ka ʻenehana hoʻomaʻemaʻe kaʻa ʻaila hou. ʻO ka mea hope loa, ke nānā nei kēia pepa i ke ʻano o ka hoʻomohala ʻana o nā mea ʻāina laha ʻole no ka hoʻomaʻemaʻe ʻana i ke kaʻa ʻaila, a me ka nānā ʻana i nā mea nui a paʻakikī o ka hoʻomaikaʻi ʻana i nā ʻoihana pili.

Nūpepa o Kina Rare Earth, i paʻi mua ʻia ma ka pūnaewele: Pepeluali 2023
