I-high lokushisa lamalahle lwamalahle
Indlela Yokulungiselela Ukukhiqiza Umkhiqizo
I-High-Light-Light Coal Tar iyinhlangano etholwe kusuka ekufuyweni okungamazinga okushisa okuphezulu kwamalahle. Kunguketshezi olumnyama olunamafutha anephunga elikhethekile. Izakhi eziphambili zingama-hydrocarbons amnandi nezinto eziphilayo eziqukethe i-oksijini, i-nitrogen, noma isibabule. Ngemuva kokugcotshwa kokuqala, izingxenyana ezinjengamafutha akhanyayo, uwoyela we-phenol, uwoyela we-naphthalene, uwoyela wokugeza, kanye namafutha we-anthracene kungatholakala ngendlela eqhubekayo yokudilizwa; Izingxenyana ezinjengamafutha akhanyayo, uwoyela ophakathi nendawo, uwoyela osindayo, futhi uwoyela we-anthracene ungatholwa usebenzisa indlela yokuzithambisa ngezikhathi ezithile; Izinsalela zokuhlobisa i-asphalt. Ukuqhutshwa okwengeziwe nokucolisiswa kwezingxenyana ezingenhla kungathola ama-benzetes, ama-phenols, naphthalene, anthrochene, i-perth.
Isingeniso sesimo se-coal tal
I-COAL TAR egumbini lokushisa lasekamelweni liwuketshezi olumnyama lwe-viscous, kanye nobuningi bocingo lwamalahle aphezulu akhiqizwa yi-coking aphezulu, kusukela ku-1.160 kuya ku-1.220g / cm3. Ngokuyinhloko eyakhiwa amakhompiyutha amnandi e-polycyclic, ngokuqukethwe okuncane kwe-ALKYL ARAmatics, izingxenye eziphezulu ezibilayo, kanye nokuqina okuhle okushisayo. Izakhi zalo zinokuqukethwe okuphezulu kweNaphthalene, kuyilapho okuqukethwe okuhlobene kuphansi, ikakhulukazi kufaka phakathi i-1-methylnaphthahthalene, i-acenaphlene, i-phenanthrene, i-venazole, i-anthracene, i-quinoline, i-pyrene, njll.
Ubuchwepheshe bokucubungula bomkhiqizo
Izakhiwo zengxenye ngayinye ye-TAR zihlukile, kepha kunezinto eziningi ezinezakhiwo ezifanayo. Kuyadingeka ukuthi uqale usebenzise izindlela zokuzithambisa ukusika izingxenyana ezahlukahlukene, njenge-phenol, naphthalene, anthracene, njll
Imikhiqizo ekhishwe oyedwa ekhishwe kugxilwe kwizingxenyana ezihambisanayo futhi ihlukaniswe futhi isebenzisa izindlela zomzimba nezamakhemikhali.
Ingxenyekazi ngaphambi kwe-170 ℃ ingamafutha akhanyayo; Ingxenyana ngo-170-20 ℃ ingamafutha we-phenolic; Ingxenyenamba enkulu ngo-210 ~ 230 ℃ yi-naphthalene Amafutha; I-distillate ngo-230-300 ℃ igeza amafutha ikakhulukazi; Ingxenyana ngo-280-360 ℃ ikakhulukazi uwoyela we-anthracene; Ingxenyana ngo-280-360 ℃ yiwoyela we-anthracene; Iphoyinti lokuqala elibilayo le-anthracene uwoyela kawoyela lingama-310 ℃, futhi lingu-400 ℃ lapho kukhuphukela ama-50%
Inhloso yomkhiqizo
I-Coal Tar ingenye yemikhiqizo ebalulekile embonini ye-Coking, accounting cishe ama-3% kuya ku-4% amalahle afakiwe. Ukwakheka kwalo kuyinkimbinkimbi kakhulu, futhi ezimweni eziningi, kwakhiwa amalahle
Imboni ye-tar isebenza ngokuhlukanisa, ukuhlanzwa, kanye nokusetshenziswa. Izingxenyana ezahlukahlukene ze-tar zingaqhutshwa futhi ukuhlukanisa imikhiqizo ehlukahlukene. Njengamanje, imikhiqizo esezingeni eliphakeme ekhishwe ifaka:
(1) I-Naphthalene isetshenziselwa ukukhiqiza i-anhydride ye-phthalic ukukhiqizwa kwama-resins, amapulasitiki wobunjiniyela kanye nodayi. Isetshenziselwa upende nomuthi.
.
.
(4) I-phenan Ngenxa yesivuno sayo esiphezulu, kusadinga ukuthuthukiswa okwengeziwe kanye nokusetshenziswa.
(5) I-Carbazole iyinto ebalulekile eluhlaza okotshani lokudla, amapulasitiki, kanye nama-pesticides.
(6) I-Asphalt iyinsalela ye-tar distillation, ingxube yamakhompiyutha ahlukahlukene we-polycyclic polymer. Isetshenziselwe ukwenza izimbobo zophahla, izingqimba zombumbulu, ukwakhiwa komgwaqo, nokukhiqizwa
I-Asphalt Coke kanye ne-Electric Furec electrodes, njll.
