Nā mea hoʻoheheʻe hydrotreatinghe kuleana koʻikoʻi i ka hoʻomaʻemaʻe ʻana i nā huahana petroleum, ʻoi loa i ka hydrodesulfurization (HDS) o ka naphtha, ka aila kinoea (VGO) a me ka sulfur diesel ultra-haʻahaʻa (ULSD). He mea koʻikoʻi kēia mau catalysts no ka wehe ʻana i ka sulfur, nitrogen a me nā mea haumia ʻē aʻe mai nā hakina aila maʻemaʻe, a laila e hoʻomaikaʻi ai i ka maikaʻi a me ka hoʻokō kūlohelohe o ka huahana hope. E hoʻomaopopo i ke koʻikoʻi ohydrotreating catalysts, he mea pono e komo i loko o ka manaʻo o ka hydrotreating a me ka hana o nā catalysts i ke kaʻina hana.
He aha ka hydrotreating catalyst?
Hydrotreating catalysts he mau mea e paipai ai i ka hoʻololi kemika i loko o ka hydrotreating o nā hakina aila. ʻO ka Hydrotreating e pili ana i kahi papa hana catalytic e pili ana i ka hoʻohana ʻana i ka hydrogen e wehe i nā haumia a hoʻomaikaʻi i ka maikaʻi o nā huahana ʻaila. ʻO nā ʻano nui oʻO ka hydroprocessing ka hydrotreating, hydrocracking, ahydrofinishing, e koi ana kēlā me kēia i nā catalysts kiko'ī i hoʻohālikelike ʻia i ka hopena i makemake ʻia.
Naphtha Hydrotreating Catalyst
ʻO ka Naphtha hydrotreating e pili ana i ka wehe ʻana i ka sulfur, nitrogen a me nā mea haumia ʻē aʻe e hoʻokō i nā hoʻoponopono kūlohelohe koʻikoʻi a hoʻomaikaʻi i ka maikaʻi o ka octane o ka huahana. Hoʻohana ʻia nā Catalysts manaphtha hydrotreatingHoʻokumu ʻia ma luna o nā metala e like me ka cobalt, molybdenum a me ka nickel i kākoʻo ʻia ma ka alumina a i ʻole nā mea kiʻekiʻe kiʻekiʻe. Hoʻolaha kēia mau mea hoʻoheheʻe i ka hydrogenation a me ka desulfurization reactions e hana i ka haʻahaʻa-sulfur, kiʻekiʻe-octane naphtha kūpono no ka hui ʻana i ka ʻaila.
VGO HDS
ʻAila ʻea kinoea(VGO) kahi meaʻai nui no nā ʻano kaʻina hana i lalo, me ka fluidized bed catalytic cracking (FCC) a me ka hydrocracking. Eia nō naʻe, loaʻa pinepine ka VGO i nā pae kiʻekiʻe o ka sulfur a me ka nitrogen, pono e hoʻemi ʻia e hoʻokō i nā kikoʻī huahana. Hydrotreating catalysts i hoʻolālā kūikawā noVGO HDSHoʻonohonoho pono ʻia e kū i nā kūlana hana paʻakikī a hoʻoikaika i ka wehe ʻana i ka sulfur a me nā pūhui nitrogen, ka hopena i ka VGO maʻemaʻe a ʻoi aku ka waiwai no ka hana hou ʻana.
Ma muli o nā kūlana hoʻokuʻu ikaika, ultra-low sulfur diesel (ULSD) he huahana nui i ka ʻoihana hoʻomaʻemaʻe hou. ʻO ka hana ʻana o ULSD e pili ana i ka hydrotreating e hōʻemi i ka ʻike sulfur i nā pae haʻahaʻa loa. He koho nui loa nā catalysts ULSD HDS no ka desulfurization ʻoiai e hōʻemi ana i ka hydrogenation o nā mea ʻē aʻe, e hōʻoiaʻiʻo ana i ka maikaʻi o ka huahana a me ka hoʻokō ʻana i nā koi kānāwai.
ʻO ke kuleana o ka catalyst
I loko o kēia mau kaʻina hana hydrotreating, hana nui nā catalysts i ka hāpai ʻana i nā hopena i makemake ʻia me ka mālama ʻana i ka paʻa a me ka hana lōʻihi. ʻO ke koho o ka hoʻokumu ʻana i ka catalyst, me ke ʻano a me ka neʻe ʻana o nā metala ikaika a me nā mea kākoʻo, pili nui i ka pono a me ke koho ʻana o ka hopena hydrotreating. Eia kekahi, ʻo ka holomua ʻana i ka ʻenehana catalyst, e like me ka hoʻomohala ʻana i nā mea hoʻomohala metala hou a me nā mea kākoʻo i hoʻomaikaʻi ʻia, e hoʻomau i ka hoʻomaikaʻi ʻana i ka hana a me ka lōʻihi o ka hydroprocessing catalysts.
i ka hopena
Nā mea hoʻoheheʻe hydrotreatinghe mea koʻikoʻi i ka hana ʻana i nā huahana petroleum ʻoi aku ka maikaʻi. I ka lilo ʻana o nā hoʻoponopono kaiapuni i ʻoi aku ka paʻakikī, e hoʻomau ka pono o nā catalysts kūpono a koho i nā kaʻina hydrotreating. Ke hoʻomau nei ka noiʻi a me ka hana hoʻomohala ʻana i ka ʻenehana catalyst e hoʻomaikaʻi hou i ka hana a me ka hoʻomau ʻana o nā catalysts hydroprocessing, e hōʻoiaʻiʻo ana i ka hana ʻana o nā wahie a me nā petrochemical e hiki mai ana.
