Coal farar, shi ne takaice ga kwal kwalta farar, kwal kwal distillation aiki bayan kau da ruwa distillate saura, nasa ne wani irin wucin gadi kwalta, kullum ga danko ruwa, Semi-m ko m, baki da kuma m, kullum dauke da carbon 92 ~ 94%, hydrogen game da 4 ~ 5%. Farar kwal ɗin kwal wani babban samfuri ne a cikin tsarin sarrafa kwal ɗin kwal kuma ɗanyen abu ne da ba za a iya maye gurbinsa ba don samar da carbon.
Manufar distillation kwalta ita ce a tattara mahaɗan da ke da maki masu tafasa iri ɗaya a cikin kwalta zuwa ɓangarorin da suka dace don ƙarin sarrafawa da rarraba samfuran monomer. Ragowar hakar distillate shine farar kwal, wanda ke lissafin kashi 50% ~ 60% na kwal ɗin kwal.
Dangane da nau'ikan laushi daban-daban, an raba kwalta kwalta zuwa ƙananan kwalta (kwalta mai laushi), matsakaiciyar zafin jiki (talakawar kwalta), babban zafin rana (kwalta mai ƙarfi) nau'i uku, kowane rukuni yana da digiri na 1 da na 2.
Ana amfani da bitumen na kwal a fannoni masu zuwa:
* Man Fetur: Ana iya haɗa ƙaƙƙarfan abubuwan da aka haɗa da mai mai nauyi ko kuma a sanya su su zama slurry da aka yi amfani da su, na iya taka rawar maye gurbin mai.
Fenti: Fentin da ke ƙara rosin ko turpentine da filaye lokacin dafa mai don gine-gine ko bututu mai hana ruwa. Ya dace da tsarin ƙarfe na waje, siminti da masonry mai hana ruwa da Layer na kariya, kuma ana iya fentin shi da fenti a zafin jiki.
* Gina titi, kayan gini: gabaɗaya gauraye da kwalta na man fetur, kwalta kwal da kwalta na man fetur idan aka kwatanta, akwai tazara mai inganci da tazarar karko. Kwalta kwal ba ta da kyau a cikin filastik, rashin kwanciyar hankali, rashin ƙarfi a lokacin hunturu, laushi a lokacin rani, da saurin tsufa.
* Mai ɗaure: Yi electrode, manna anode da sauran samfuran carbon mai ɗaure, gabaɗayan gyaran kwalta. Gabaɗaya, ana shirya kwalta da aka gyara daga kwalta ta matsakaicin zafin jiki. A kasar Sin, ana amfani da tsarin dumama tukwane gabaɗaya, kuma ana amfani da iskar gas a matsayin mai don dumama kwalta a ma'aunin wutar lantarki. A ƙarshe, ana samun ingantaccen kwalta mai ƙarfi ta hanyar rabuwa da granulation.
* Kwalta coke: m ragowar kwalta kwalta bayan high zafin jiki retoring ko jinkirta coking. Ana amfani da coke na kwalta sau da yawa azaman albarkatun ƙasa don kayan carbon na musamman, wanda ba makawa ne don kera semiconductor da kayan aikin samar da hasken rana. An yi amfani da ko'ina azaman lantarki abu don aluminum refining, carbonized abu ga lantarki tanderu steelmaking da kuma musamman carbon samfurin albarkatun kasa na semiconductor.
* Allura coke: mai ladabi kwalta da albarkatun kasa pretreatment, jinkirta coking, high zafin jiki calcination matakai uku, yafi amfani a lantarki masana'antu da kuma musamman carbon kayayyakin. Samfuran da aka yi daga albarkatun ƙasa suna da alaƙa da ƙarancin juriya, ƙarancin haɓaka haɓaka haɓakar thermal, juriya mai ƙarfi mai ƙarfi, ƙarfin injiniya mai ƙarfi da juriya mai kyau na iskar shaka.
* Carbon fiber: fiber na musamman tare da fiye da 92% abun ciki carbon da aka samu daga kwalta ta hanyar tacewa, kadi, pre-oxidation, carbonization ko graphitization.
* Jikin mai, carbon da aka kunna, carbon baki da sauran amfani.
