Isixa esikhulu somsi we-asphalt ohlakaziweyo kunye noxinzelelo lwe-5-7mg / m ~ 3 iveliswa ngexesha lenkqubo yokuvelisa i-carbon workshop yesityalo se-alumina.Ukuba ikhutshwe ngokuthe ngqo, iya kuba nefuthe elibi kwindawo engqongileyo kunye nabasebenzi basefektri.Ijolise kulo mphunga we-pitch, i-particle encinci calcined coke isetyenziselwa ukufunxa kunye nokuhlanjululwa kwayo, kwaye i-coke egcwele i-calcined ihlaziywa yindlela yokuvuselela i-thermal.

Okokuqala, inkqubo ye-adsorption ye-coke e-calcined yafundwa, kwaye imiphumo yokushisa kwe-adsorption, i-pitch fome concentration, i-space velocity kunye ne-particle size ye-coke e-calcined kwi-adsorption effect ye-coke ye-calcined yahlalutywa.Iziphumo zophando zibonisa ukuba isixa somsi wepitch obhengezwa yicoke ekhalisiwe siyenyuka ngokunyuka koxinzelelo lwe-inlet lomsi womsi.Isantya esisezantsi sendawo, ubushushu obuphantsi, kunye nobungakanani bamasuntswana amancinci zonke ziluncedo kwi-adsorption ye-pitch fume nge-coke calcined.I-adsorption thermodynamics ye-coke e-calcined yafundwa, ebonisa ukuba inkqubo ye-adsorption yayiyi-adsorption yomzimba.Ukuhlehla kwe-adsorption isotherm kubonisa ukuba inkqubo ye-adsorption ihambelana ne-equation yaseLangmuir.

Okwesibini, ukufudumeza ukuvuselelwa kunye nokubuyiswa kwe-condensation ye-coke egcwele i-calcined.Iimpembelelo zesantya sokuhamba kwerhasi yomthwali, ubushushu bokufudumala, isixa secoke esigcweleyo esine-calcined kunye namaxesha okuhlaziya kwintsebenzo yokuvuselela i-coke ye-calcined zaphandwa ngokulandelelana.Iziphumo zovavanyo zibonisa ukuba xa isantya sokuhamba kwegesi ye-carrier carrier inyuka, ukushisa kweqondo lokushisa kuyanda, kwaye inani le-coke emva kokuba i-calcining egcweleyo iyancipha, kunenzuzo ekuphuculeni ukusebenza kakuhle.I-Condensate kwaye ifunxe i-gas yokuvuselela umsila, kwaye izinga lokubuyisela lingaphezulu kwe-97%, ebonisa ukuba i-condensation kunye nendlela yokufunxa inokubuyisela i-bitumen kwi-gas yokuvuselela umsila kakuhle.

Ekugqibeleni, iinkqubo ezintathu zokuqokelela igesi, ukuhlanjululwa kunye nokuhlaziywa kwakhona ziyilwe, kwaye iziphumo zoyilo ziyasetyenziswa.Iziphumo zokusetyenziswa kwemizi-mveliso zibonisa ukuba ukucocwa komsi we-asphalt kunye ne-benzo(a)pyrene kufikelela kwi-85.2% kunye ne-88.64%, ngokulandelelanayo, xa isicoci sisetyenziselwa ukubamba kunye nokucoca imisi ye-asphalt esasazekileyo kunye engacwangciswanga.Ugxininiso lomsi we-asphalt kunye ne-benzo (a) ipyrene kwindawo yokuphuma yesicoci yayiyi-1.4mg/m~3 kunye ne-0.0188μg/m~3, kwaye ukukhutshwa kwakuyi-0.04kg/h kunye ne-0.57×10~(-6)kg. /h, ngokulandelelanayo.Ifikelele kumgangatho wesibini wokukhutshwa okubanzi kongcoliseko lomoya i-GB16297-1996.
