Ka ʻike o ka petroleum coke a me ka calcined petroleum coke
1. ʻAla ʻaila coke
ʻO ka Petroleum coke kahi huahana ʻaila paʻa paʻa paʻa paʻa ʻeleʻele a hina ʻeleʻele paha me ka luster metala a he porous.ʻO nā ʻāpana coke Petroleum he hydrocarbons, he 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur a me nā mea metala kaumaha.
ʻO ka Petroleum coke kahi huahana o ka pyrolysis o ka ʻaila feedstock i nā ʻāpana coking lohi i nā wela kiʻekiʻe e hana i nā huahana aila māmā.ʻO ka huahana o ka petroleum coke 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%, ʻo ka mea volatile e pili ana i 11%, a ua kokoke ka maikaʻi i ka anthracite.
2. ʻO ke kūlana maikaʻi o ka petroleum coke
ʻO ka coke ʻaila hoʻopaneʻe e pili ana i ka coke ʻōmaʻomaʻo i hana ʻia e ka hui coking lohi, ʻike ʻia hoʻi ʻo ka coke maʻamau, a ʻaʻohe kūlana ʻāina kūpono i kēia manawa.I kēia manawa, hana nui nā ʻoihana hana home e like me ke kūlana ʻoihana SH0527-92 i hoʻokumu ʻia e ka Sinopec Corporation.Hoʻokaʻawale nui ʻia ka maʻamau e like me ka sulfur content o ka petroleum coke.Ma waena o lākou, kūpono ka coke papa mua a me ka No.Hoʻohana ʻia ka coke No. 2 i ka ʻoihana hana alumini.Electrode paste i hoʻohana 'ia i loko o electrolytic cell ( umu ahi) a me ka hana ana o graphite electrodes, No. 3 coke ua hoʻohana 'ia no ka hana ana i ka silicon carbide (abrasive mea) a me ka calcium carbide (calcium carbide), a me nā huahana kalapona 'ē aʻe, i hoʻohana 'ia i ka hana o anodes no ka alumini hooheheeia pahu Poka lalo a hoohana ia no ka umu puhi kalapona kapili kalapona a i ole ka umu ahi i hanaia malalo.
3. ʻO ka hoʻohana nui ʻana i ka petroleum coke
ʻO ka hoʻohana nui ʻana o ka petroleum coke he anodes i hoʻomoʻa mua ʻia a me nā anode pastes i hoʻohana ʻia i ka alumini electrolytic, carbon carbon production carbon enhancers, graphite electrodes, smelting industrial silicon, a me nā wahie.
E like me ke ʻano a me ke ʻano o ka petroleum coke, hiki ke hoʻokaʻawale ʻia nā huahana coke petroleum i 4 mau ʻano: coke needle, sponge coke, projectile coke a me ka pauka coke: (1) Needle coke, me ke ʻano o ka nila a me ke ʻano fiber, hoʻohana nui ʻia. no ka hana kila High-power graphite electrodes a me ka ultra-high-power graphite electrodes ma No ka mea, he koʻikoʻi ko ka needle coke e pili ana i ka sulfur content, ka lehu lehu, ka mea volatile a me ka paʻa maoli, aia nā koi kūikawā no ka ʻenehana hana ʻenehana coke a me ka maka. mea waiwai.
(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 ma ke ʻano a he 0.6-30mm ke anawaena.Hana ʻia ia mai ka ʻaila koena kiʻekiʻe-sulfur a kiʻekiʻe-asphaltene a hiki ke hoʻohana wale ʻia e like me nā wahie ʻoihana e like me ka hana mana a me ka sima.
(4) Powder coke: Ua hanaʻia e ka fluidized coking process, me nā'āpana maikaʻi (0.1-0.4mm i ke anawaena), kiʻekiʻe volatile content a me ke kiʻekiʻe thermal expansion coefficient, aʻaʻole hiki ke hoʻohana ponoʻia i ka hoʻomākaukau electrode a me kaʻoihana kalapona.
