ʻO ka wehewehe ʻana i ka huahana petroleum coke

ʻO ka calcined coke kahi ʻano carburizer a me ka petroleum coke o nā kikoʻī like ʻole.
ʻO nā kikoʻī nui o nā huahana graphite ʻo ￠150-￠1578 a me nā hiʻohiʻona ʻē aʻe. He mea koʻikoʻi ia no nā ʻoihana hao a me ke kila, ʻoihana silicon polysilicon ʻoihana, ʻoihana emery, ʻoihana aerospace a me nā huahana ʻē aʻe.

1: ʻAla ʻaila coke
ʻO ka Petroleum coke kahi mea ʻaila paʻa paʻa paʻa paʻa ʻeleʻele a ʻeleʻele paha me ka ʻulaʻula metala a he porous. He mea kalapona, columnar, a i ʻole ka nila-like carbonaceous i loko o nā kristal graphite microscopic.
ʻO ka Petroleum coke nā hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur, a me nā mea metala kaumaha.

ʻO ka Petroleum coke ka huahana o ka pyrolysis o ka aila maka i loko o ka hui coking lohi e hana i ka aila māmā i ka wela kiʻekiʻe.
ʻO ka huahana o ka coke petroleum ma kahi o 25-30% o ka aila maka.
ʻO kona haʻahaʻa haʻahaʻa calorific e pili ana i ka 1.5-2 mau manawa o ka lanahu, ʻaʻole i ʻoi aku ka nui o ka lehu ma mua o 0.5%, ʻoi aku ka nui o ka volatile ma kahi o 11%, a ua kokoke kona ʻano i ka anthracite.

2: ʻO ke kūlana maikaʻi o ka petroleum coke ʻO ka coke petroleum lohi e pili ana i ka coke i hana ʻia e ka hui coking lohi, ʻike ʻia hoʻi ʻo coke maʻamau, ʻaʻohe ## maʻamau.
I kēia manawa, hana nui nā ʻoihana hana home e like me ka maʻamau ʻoihana SH0527-92 i hoʻokumu ʻia e ka China Petrochemical Corporation.
Hoʻokaʻawale nui ʻia ka maʻamau e like me ka sulfur content o ka petroleum coke.
No. 1 coke kūpono no ka hana ʻana i ka mana graphite electrode maʻamau i ka ʻoihana hana kila, a hoʻohana ʻia hoʻi e like me ke kalapona no ka hoʻomaʻemaʻe alumini.
No. 2 coke ua hoʻohana 'ia no ka electrode paste a me ka graphite electrode hana ma electrolytic cell ( umu ahi) i ka alumini hooheheeia oihana.
Hoʻohana ʻia ka coke No. 3 i ka hana ʻana i ka carbide silicon (mea wili) a me ka calcium carbide (calcium carbide), a me nā huahana kalapona ʻē aʻe, a me ka hana ʻana i nā poloka anode no ka hoʻoheheʻe alumini a me ke kūkulu ʻana i ke kalapona kalapona. nā pōhaku lepo a i ʻole ka umu ahi ma lalo o ka umu ahi.
3: nā mea hoʻohana nui o ka petroleum coke
ʻO ka hoʻohana nui o ka petroleum coke he anode mua a me ka anode paste no ka alumini electrolytic, ka hana kalapona o ka carbonizing agent, graphite electrode, smelting industrial silicon and fuel, etc.

E like me ke ʻano a me ke ʻano o ka petroleum coke, hiki ke hoʻokaʻawale ʻia nā huahana coke petroleum i ka coke needle, sponge coke, projectile coke a me ka pauka coke:
(1) Hoʻohana nui ʻia ka coke me ke ʻano like me ka nila a me ke ʻano fiber, e like me ka electrode graphite kiʻekiʻe a me ka electrode graphite ultra-high-power i ka hana kila.
No ka mea, he koʻikoʻi koʻikoʻi ko ka coke koki i ka ʻike sulfur, ka lehu, ka ʻikepili volatile a me ka ʻano maoli, aia nā koi kūikawā i ka ʻenehana hana a me nā mea maka o ka nila coke.

(2) Sponge coke, me ke kiʻekiʻe kemika reactivity a me ka haʻahaʻa haumia maʻiʻo, ua nui hoʻohana 'ia i loko o ka alumini hooheheeia oihana a me carbon.

(3) Projectile coke a spherical coke: he spherical i ke ʻano a he 0.6-30mm ke anawaena. Hana ʻia ia mai ke koena kiʻekiʻe-sulfur a me ka kiʻekiʻe-asphaltene a hiki ke hoʻohana wale ʻia no ka hana mana, sima a me nā wahie ʻoihana ʻē aʻe.

(4) Coke pauka: hana ʻia e ka fluidized coking kaʻina me nā ʻāpana maikaʻi (diameter: 0.1-0.4mm), kiʻekiʻe volatilization maʻiʻo a me ke kiʻekiʻe thermal expansion coefficient, no laila ʻaʻole hiki ke hoʻohana pololei ʻia i ka hoʻomākaukau electrode a me ka ʻoihana kalapona.

4: Koke ʻaila i hoʻopaʻa ʻia
Ke hoʻokō ka graphite electrode no ka hana kila a i ʻole ka anode paste (melting electrode) no ka aluminika a me ka magnesium, i mea e hoʻokō ai i ka petroleum coke (coke) i nā koi, pono e calcined ka coke.
ʻO ka mahana calcining ka mea maʻamau ma kahi o 1300 ℃, ke kumu o ia e hoʻopau i ka volatilization naphthol coke i kahi hiki loa.
Ma kēia ala, hiki ke hoʻemi ʻia ka maʻi hydrogen o ka petroleum coke reproducts, hiki ke hoʻomaikaʻi i ka degere graphitization o ka coke petroleum, hiki ke hoʻomaikaʻi ʻia ka ikaika kiʻekiʻe a me ka wela o ka graphite electrode, a hiki ke hoʻomaikaʻi ʻia ka conductivity uila o ka graphite electrode. .
Hoʻohana nui ʻia ʻo Calcining e hana i ka graphite electrode, carbon paste huahana, Diamond sand, food-grade phosphorus industry, metallurgical industry and calcium carbide, i waena o ka graphite electrode i hoʻohana nui ʻia.
Hiki ke hoʻohana pololei ʻia ka Coke me ka ʻole o ka forging 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 ka coke no ka ʻoihana metallurgical blast furnace a i ʻole blast furnace lining carbon brick, hiki ke hoʻohana ʻia no ka hoʻolei ʻana i ka coke compact, etc.
