ʻO ka wehewehe a me nā kūlana maʻemaʻe o ka maʻemaʻe kiʻekiʻeMethane

Maʻemaʻe kiʻekiʻemethanepili i ke kinoea methane me ka maʻemaʻe kiʻekiʻe. ʻO ka maʻamau, ʻo ka methane me ka maʻemaʻe o 99.99% a i ʻole ke kiʻekiʻe aʻe hiki ke manaʻo ʻia he maʻemaʻe kiʻekiʻemethane. Ma kekahi mau noi koʻikoʻi, e like me ka ʻoihana uila, hiki i nā koi maʻemaʻe ke piʻi i 99.999% a i ʻole ke kiʻekiʻe. Loaʻa kēia maʻemaʻe kiʻekiʻe ma o ka hoʻomaʻemaʻe kinoea paʻakikī a me nā ʻenehana hoʻokaʻawale e wehe i nā mea haumia e like me ka moisture, carbon dioxide, carbon monoxide, hydrogen, a me nā mea kinoea ʻē aʻe.

Nā wahi noi o ka methane maʻemaʻe kiʻekiʻe

I ka ʻoihana uila,methane maʻemaʻe kiʻekiʻeHoʻohana ʻia ʻo ia ma ke ʻano he etching gas a me kahi mea maka no ka hoʻoheheʻe ʻana i ka mahu (CVD) i ka hana semiconductor. No ka laʻana, i loko o ka etching plasma, ua hui pū ʻia ka methane me nā kinoea ʻē aʻe e kālai pono i nā mea semiconductor, e hana ana i nā ʻano kaapuni liʻiliʻi. Ma CVD,methanehāʻawi i kahi kumu kalapona no ka ulu ʻana i nā kiʻi ʻoniʻoni ʻoniʻoni i hoʻokumu ʻia i ke kalapona, e like me nā kiʻiʻoniʻoni silicon carbide, kahi hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka hana a me ke kūpaʻa o nā mea semiconductor.

Nā Mea Kimepika:Methane maʻemaʻe kiʻekiʻehe mea waiwai nui ia no ka hoʻohui ʻana i nā kinikona waiwai nui. No ka laʻana, hiki iā ia ke hana me ka chlorine e hana i nā pūhui chloromethane e like me chloroform, dichloromethane, trichloromethane, a me carbon tetrachloride. ʻO Chloromethane kahi mea maka no ka hana ʻana i nā pūhui organosilicon, ʻo dichloromethane a me trichloromethane ka mea maʻamau i hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe, a ua hoʻohana mua ʻia ka carbon tetrachloride ma ke ʻano he mea kinai ahi, akā ua kaupalena ʻia kona hoʻohana ʻana ma muli o kona hopena ozone-depleting. Eia kekahi,methanehiki ke hoʻololi ʻia i syngas (kahi hui ʻana o ka carbon monoxide a me ka hydrogen) ma o ka hoʻoponopono ʻana i nā hopena, a ʻo ka syngas kahi kumu kumu no ka hana ʻana i ka methanol, synthetic ammonia, a me nā huahana kemika he nui.

Ma ka ʻāpana ikehu: ʻOiai ʻo ka methane maʻamau (ke kinoea maoli) ka punawai ikehu mua,methane maʻemaʻe kiʻekiʻehe kuleana nō hoʻi i kekahi mau noi ikehu kūikawā. No ka laʻana, i loko o nā pūnaewele wahie, hiki ke hoʻohana ʻia ka methane maʻemaʻe kiʻekiʻe e like me ka wahie, e hana ana i ka hoʻoponopono hou ʻana e hana i ka hydrogen, nāna e hoʻoikaika i ka cell fuel. Ke hoʻohālikelike ʻia me nā wahie mōʻalihaku maʻamau, ʻoi aku ka maikaʻi o ka ikehu kiʻekiʻe a me ka hoʻohaʻahaʻa ʻana i nā mea hoʻohaumia.

Hoʻomākaukau i nā kinoea maʻamau:Methane maʻemaʻe kiʻekiʻehiki ke hoʻohana ʻia ma ke ʻano he kinoea maʻamau no ka calibration o nā mea hana loiloi kinoea. No ka laʻana, i loko o ke kinoea chromatograph, hoʻohanamethane maʻemaʻe kiʻekiʻeHiki i ke kinoea maʻamau o ka ʻike ʻike ʻia ke calibrate i ka ʻike a me ka pololei o ka mea kani, e hōʻoia ana i nā hopena analytical pololei a hilinaʻi no nā kinoea ʻē aʻe.
