Coal pitch, dị mkpụmkpụ maka coal tar pitch, coal tar distillation nhazi mgbe mwepụ nke mmiri mmiri distillate fọdụrụnụ, bụ nke a ụdị artificial asphalt, n'ozuzu maka viscous mmiri mmiri, ọkara siri ike ma ọ bụ siri ike, nwa na-egbu maramara, n'ozuzu nwere carbon 92. ~ 94%, hydrogen banyere 4 ~ 5%. Coal tar pitch bụ ngwaahịa bụ isi na nhazi nke coal tar na bụ akụrụngwa na-enweghị ike dochie anya maka mmepụta carbon.
Ebumnuche nke mgbasa tar bụ itinye uche na ogige ndị nwere isi ihe na-esi esi na tar ka ọ bụrụ akụkụ ndị kwekọrọ maka nhazi na nkewa nke ngwaahịa monomer. Ihe fọdụrụ na mmịpụta distillate bụ coal tar pitch, na-aza 50% ~ 60% nke coal tar.
Dị ka ihe dị nro dị iche iche si dị, a na-ekewa asphalt coal n'ime obere okpomọkụ asphalt (asphalt dị nro), ọkara okpomọkụ asphalt (nkịtị asphalt), nnukwu okpomọkụ asphalt (ike asphalt) atọ, ụdị nke ọ bụla nwere akara nke 1 na nke 2 abụọ. .
A na-ejikarị bitumen coal eme ihe n'ubi ndị a:
* Mmanụ: Enwere ike ịgwakọta ihe siri ike na mmanụ dị arọ ma ọ bụ mee ka ọ bụrụ slurry, nwere ike rụọ ọrụ nke dochie mmanụ dị arọ.
Agba: Agba nke na-agbakwunye rosin ma ọ bụ turpentine na ihe ndị na-ejuputa mgbe ị na-esi mmanụ maka ụlọ ma ọ bụ ọkpọkọ mmiri. Ọ dị mma maka nhazi nchara n'èzí, ihe mkpuchi na akwa mkpuchi mmiri na oyi akwa mkpuchi, a pụkwara ịcha ya ma na-ese ya na ụlọ okpomọkụ.
* Owuwu okporo ụzọ, ihe eji arụ ụlọ: a na-agwakọta ya na asphalt petroleum, coal asphalt na petroleum asphalt tụnyere, enwere ọdịiche dị mma doro anya na ogologo ịdịte aka. Asphalt coal adịghị mma na rọba, ọ naghị enwe nkwụsi ike nke okpomọkụ, na-agbaji n'oge oyi, na-adị nro n'oge okpomọkụ, na ịka nká ngwa ngwa.
* Ihe nchikota: Mee electrode, tapawa anode na ngwaahịa carbon ndị ọzọ na-ekekọta, asphalt a na-agbanwekarị. N'ozuzu, a na-akwado asphalt a gbanwere site na asphalt okpomọkụ. Na China, a na-anabatakarị usoro ikpo ọkụ kettle, a na-ejikwa gas dị ka mmanụ ọkụ iji kpoo asphalt na reactor. N'ikpeazụ, a na-enweta asphalt siri ike gbanwere site na nkewa na granulation.
* Asphalt coke: ihe fọdụrụ siri ike nke coal asphalt mgbe oke okpomoku meghariri ma ọ bụ na-egbu oge coking. A na-ejikarị asphalt coke eme ihe dị ka akụrụngwa maka ihe carbon pụrụ iche, nke dị mkpa maka imepụta semiconductor na akụrụngwa mmepụta nke anyanwụ. A na-eji ya eme ihe dị ka ihe elektrọn maka nnụcha aluminom, ihe carbonized maka igwe ọkụ ọkụ eletrik na akụrụngwa ngwaahịa carbon pụrụ iche maka semiconductor.
* coke agịga: asphalt a nụchara anụcha dị nro site na pretreatment akụrụngwa, coking na-egbu oge, usoro ikpo ọkụ dị elu, nke a na-ejikarị na nrụpụta electrode na ngwaahịa carbon pụrụ iche. A na-eji ngwaahịa ndị sitere na akụrụngwa ya mara obere resistivity, ọnụọgụ mgbasawanye ọkụ dị ala, nguzogide okpomọkụ siri ike, ike igwe dị elu na nguzogide oxidation dị mma.
* Carbon fiber: eriri pụrụ iche nwere ihe karịrị 92% carbon ọdịnaya enwetara site na asphalt site n'ịnụcha, ịtụgharị, pre-oxidation, carbonization or graphitization.
* Mmanụ nwere mmetụta, carbon na-arụ ọrụ, carbon ojii na ojiji ndị ọzọ.
