ʻO ka coke calcined kahi ʻano carburizer a me ka petroleum coke o nā kikoʻī like ʻole.
ʻO nā kikoʻī nui o nā huahana graphite he 150- 1578 a me nā hiʻohiʻona ʻē aʻe. He mea pono ia no nā ʻoihana hao a me ke kila, nā ʻoihana silicon polysilicon ʻoihana, nā ʻoihana emery, ka ʻoihana mea aerospace a me nā huahana ʻē aʻe.
1: Koke ʻaila
He huahana petroleum paʻa ʻeleʻele a hina hina paha ka petroleum coke me kahi ʻōlinolino metala a he porous. He mea kalapona granular, kolamu, a nila paha i hana ʻia me nā kristal graphite microscopic.
ʻO ka coke petroleum he hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur, a me nā metala kaumaha.
ʻO ka petroleum coke ka huahana o ka pyrolysis o ka ʻaila maka i loko o ka ʻāpana coking lohi e hana i ka ʻaila māmā ma ke ana wela kiʻekiʻe.
ʻO ka nui o ka hana o ka petroleum coke he 25-30% o ka hana o ka aila maka.
ʻO kona waiwai hoʻomehana haʻahaʻa ma kahi o 1.5-2 mau manawa o ka lanahu, ʻaʻole ʻoi aku ka nui o ka lehu ma mua o 0.5%, ʻo ka nui o ka volatile ma kahi o 11%, a kokoke kona ʻano i ka anthracite.
2: Kūlana maikaʻi o ka petroleum coke ʻO ka delayed petroleum coke e pili ana i ka coke i hana ʻia e ka ʻāpana coking delayed, i ʻike ʻia hoʻi he coke maʻamau, ʻaʻohe kūlana ## e pili ana.
I kēia manawa, hana nui nā ʻoihana hana kūloko e like me ke kūlana ʻoihana SH0527-92 i hoʻokumu ʻia e ka China Petrochemical Corporation mua.
Hoʻokaʻawale nui ʻia ke kūlana e like me ka nui o ka sulfur o ka petroleum coke.
He kūpono ka coke helu 1 no ka hana ʻana i ka electrode graphite mana maʻamau i ka ʻoihana hana kila, a hoʻohana ʻia hoʻi e like me ke kalapona no ka hoʻomaʻemaʻe alumini
Hoʻohana ʻia ka coke helu 2 no ka hoʻopili electrode a me ka hana ʻana o ka electrode graphite i loko o ke kelepona electrolytic (kapuahi) i ka ʻoihana hoʻoheheʻe alumini
Hoʻohana ʻia ka coke helu 3 i ka hana ʻana o ka silicon carbide (mea wili) a me ka calcium carbide (calcium carbide), a me nā huahana kalapona ʻē aʻe, a me ka hana ʻana o nā poloka anode no ka mea hoʻoheheʻe alumini a me ke kūkulu ʻana i nā piliki uhi kalapona a i ʻole ka lalo o ka umu i loko o ka umu pahū.
3: nā hoʻohana nui o ka petroleum coke
ʻO nā hoʻohana nui o ka petroleum coke he anode i hoʻomoʻa mua ʻia a me ka anode paste no ka alumini electrolytic, ka hana kalapona o ka mea hoʻoheheʻe carbonizing, ka electrode graphite, ka hoʻoheheʻe ʻana i ka silicon ʻoihana a me ka wahie, a pēlā aku.
Wahi a ke ʻano a me ke ʻano o ka petroleum coke, hiki ke hoʻokaʻawale ʻia nā huahana petroleum coke i ka nila coke, ka sponge coke, ka projectile coke a me ka powder coke.
(1) ʻO ke koka ʻano nila, me ke ʻano nila a me ke ʻano o ka fiber, hoʻohana nui ʻia e like me ke electrode graphite mana kiʻekiʻe a me ke electrode graphite mana kiʻekiʻe loa i ka hana kila.
Ma muli o nā koi koʻikoʻi o ka nila coke i ka ʻike sulfur, ka lehu, ka volatiles a me ka nui maoli, aia nā koi kūikawā ma ka ʻenehana hana a me nā mea maka o ka nila coke.
(2) ʻO ka coke huʻa, me ka hana kemika kiʻekiʻe a me ka haʻahaʻa o ka haumia, hoʻohana nui ʻia i ka ʻoihana hoʻoheheʻe alumini a me ka ʻoihana kalapona.
(3) Coke projectile a i ʻole coke poepoe: he ʻano poepoe kona a he 0.6-30mm ke anawaena. Hana ʻia ia mai ke koena sulfur kiʻekiʻe a me ka asphaltene kiʻekiʻe a hiki ke hoʻohana wale ʻia no ka hana mana, ka sima a me nā wahie ʻoihana ʻē aʻe.
(4) Coke pauka: hana ʻia ia ma o ke kaʻina hana coking fluidized me nā ʻāpana liʻiliʻi (diameter: 0.1-0.4mm), ka nui o ka volatilization a me ke coefficient hoʻonui thermal kiʻekiʻe, no laila ʻaʻole hiki ke hoʻohana pololei ʻia i ka hoʻomākaukau ʻana o ka electrode a me ka ʻoihana kalapona.
4: Coke petroleum i hoʻopaʻa ʻia
I ka wā e hoʻokō ai ka electrode graphite no ka hana kila a i ʻole ka anode paste (helting electrode) no ka alumini a me ka magnesium, i mea e hoʻokō ai ka petroleum coke (coke) i nā koi, pono e calcined ka coke.
ʻO ka mahana calcining maʻamau ma kahi o 1300℃, ʻo ke kumu o ia mea e hoʻopau i ka volatilization naphthol coke i ka hiki.
Ma kēia ʻano, hiki ke hoʻemi ʻia ka nui o ka hydrogen o nā huahana petroleum coke, hiki ke hoʻomaikaʻi ʻia ke kekelē graphitization o ka petroleum coke, hiki ke hoʻomaikaʻi ʻia ka ikaika wela kiʻekiʻe a me ke kūpaʻa wela o ka electrode graphite, a hiki ke hoʻomaikaʻi ʻia ka conductivity uila o ka electrode graphite.
Hoʻohana nui ʻia ka calcining no ka hana ʻana i nā electrode graphite, nā huahana kāpili kalapona, ke one Diamond, ka ʻoihana phosphorus papa meaʻai, ka ʻoihana metallurgical a me ka calcium carbide, kahi i hoʻohana nui ʻia ai ka electrode graphite.
Hiki ke hoʻohana pololei ʻia ʻo Coke me ka hoʻopaʻa ʻole ʻia e like me ka calcium carbide, silicon carbide a me ka boron carbide e like me nā mea wili.
Hiki ke hoʻohana pololei ʻia e like me ke coke no ka ʻoihana metallurgical pahū umu a i ʻole ka uhi ʻana o ka umu pahū i nā pōhaku kalapona, hiki ke hoʻohana ʻia no ke kaʻina hana hoʻolei coke paʻa, a pēlā aku.
