ʻO ka dewaxing catalyticHe hana koʻikoʻi i ka ʻoihana ʻaila e hoʻoneʻe i nā pūhui waxy mai ka ʻaila ʻaila. He mea koʻikoʻi kēia kaʻina hana i ka hōʻoia ʻana e loaʻa i nā huahana ʻaila e like me ka diesel, gasoline, a me ka wahie jet i nā waiwai haʻahaʻa i makemake ʻia. Ma kēia ʻatikala, e kūkākūkā mākou i ka catalytic dewaxing, pehea e hana ai, a me kona koʻikoʻi i ka ʻoihana ʻaila.

He aha ka Catalytic Dewaxing?

ʻO ka catalytic dewaxing kahi hana hoʻomaʻemaʻe e hoʻoneʻe i nā pūhui waxy, e like me nā paraffins, mai ka ʻaila ʻaila. ʻO kēia mau pūhui waxy ke kuleana no ka hoʻopaʻa ʻana o nā huahana petroleum i nā haʻahaʻa haʻahaʻa, hiki ke hoʻopilikia i ka hana nui, ʻoi aku hoʻi i ke anuanu. Hoʻohana ke kaʻina hana i ka catalyst e hoʻololi i nā pūhui waxy i loko o ka wai hydrocarbons, e hoʻomaikaʻi ana i nā waiwai haʻahaʻa haʻahaʻa o nā huahana ʻaila.

Pehea e hana ai ka Catalytic Dewaxing?

ʻO ka dewaxing catalyticʻelua mau ʻanuʻu: hydrocracking a me isomerization. Hoʻopau ka Hydrocracking i nā pūhui waxy lōʻihi i loko o nā molekole liʻiliʻi, ʻoiai ʻo ka isomerization e hoʻonohonoho hou i nā molekole e hana i nā hydrocarbons kaulahao lālā i makemake ʻia. He haʻahaʻa ko kēia mau lālā hoʻoheheʻe ʻia ma mua o ka hydrocarbons kaulahao pololei, e hoʻomaikaʻi ana i nā waiwai haʻahaʻa haʻahaʻa o nā huahana ʻaila.

Hana ʻia ke kaʻina hana i loko o kahi moku reactor, kahi i hui pū ʻia ai ka ʻaila ʻaila me ke kinoea hydrogen a me ka catalyst. Hoʻomaʻamaʻa ʻia ka hui ʻana i nā wela kiʻekiʻe a me nā kaomi, a ua hoʻololi ʻia nā pūhui waxy i loko o ka wai hydrocarbons. Hoʻokaʻawale ʻia nā hydrocarbons wai mai ka catalyst a me nā mea i hana ʻole ʻia a hoʻouna ʻia i nā hana hoʻomaʻemaʻe hou.

No ke aha he mea nui ka Catalytic Dewaxing?

Pono ka catalytic dewaxing i ka hōʻoia ʻana e loaʻa i nā huahana petroleum nā waiwai haʻahaʻa haʻahaʻa i makemake ʻia. No ka laʻana, pono e hoʻomau ka wahie diesel i ka wai ma nā mahana haʻahaʻa e hōʻoia i ka hiki ke puhi ʻia a puhi maikaʻi ʻia i ke anuanu. Inā paʻa ka wahie diesel, hiki iā ia ke hoʻopaʻa i nā laina wahie, nā kānana, a me nā injectors, e hoʻokau i nā pilikia koʻikoʻi. Pēlā nō, pono e noho wai ka wahie jet i nā haʻahaʻa haʻahaʻa e hōʻoia i ka palekana a me ka maikaʻi o ka hana ʻana o nā mokulele i ke anuanu.

Hoʻomaikaʻi pū ʻo Catalytic dewaxing i ka maikaʻi holoʻokoʻa o nā huahana ʻaila. Ma ka hoʻololi ʻana i nā pūhui waxy i loko o nā hydrocarbons makemake nui ʻia, hiki i ke kaʻina hana ke hoʻomaikaʻi i ka helu cetane o ka wahie diesel a me ka helu octane o ka ʻaila, e hoʻomaʻemaʻe a maikaʻi iā lākou.

Ma kahi o kona koʻikoʻi i ka ʻoihana ʻaila, ua loaʻa i ka catalytic dewaxing nā pono kaiapuni. Ma ka hoʻomaikaʻi ʻana i ka maikaʻi o nā huahana petroleum, hiki i ke kaʻina hana ke hōʻemi i nā hoʻokuʻu a hoʻomaikaʻi i ka maikaʻi o ka ea. Hiki i nā wahie puhi maʻemaʻe me nā helu cetane a me ka octane kiʻekiʻe ke hōʻemi i nā hoʻokuʻu ʻino e like me ka nitrogen oxides (NOx) a me nā mea ʻala, e hāʻawi ana i kahi nohona olakino.

Ka hoohana ana ohoʻoheheʻe ʻiake piʻi nui nei i ka ʻoihana ʻaila ma muli o ka ulu nui ʻana o ka noi no nā wahie kiʻekiʻe, haʻahaʻa haʻahaʻa. Ke ulu mau nei ke kaʻina hana, me ka holomua o ka ʻenehana catalyst a me ka hoʻolālā kaʻina hana e hoʻomaikaʻi ana i kona pono a me ka pono.

I ka hopena, he hana koʻikoʻi ka catalytic dewaxing i ka ʻoihana ʻaila e hoʻoneʻe i nā pūhui waxy mai ka ʻaila ʻaila e hoʻomaikaʻi i nā waiwai haʻahaʻa haʻahaʻa a me ka maikaʻi holoʻokoʻa o nā huahana petroleum. ʻO ke kaʻina hana e pili ana i ka hydrocracking a me ka isomerization a hoʻohana i ka catalyst e hoʻololi i nā pūhui waxy i loko o ka wai hydrocarbons. He mea nui ka catalytic dewaxing i ka hōʻoia ʻana i ka palekana a me ka maikaʻi o ka hana ʻana o nā huahana petroleum i ke anuanu, hoʻomaikaʻi i ka maikaʻi o ka ea, a me ka hoʻokō ʻana i ka ulu ʻana o ka noi no nā wahie kiʻekiʻe, haʻahaʻa haʻahaʻa.
