Qadar badan oo qiiqa asfalt ah oo kala firdhiyey oo leh fiirsashada 5-7mg / m ~ 3 ayaa la soo saaraa inta lagu jiro habka wax soo saarka ee aqoon-is-weydaarsiga kaarboon ee warshadda alumina.Haddii si toos ah looga saaro, waxay saameyn xun ku yeelan doontaa deegaanka ku hareeraysan iyo shaqaalaha warshadda.Ujeeddada qiiqa garoonka, kookaha qurub yar oo la kariyey ayaa loo isticmaalaa in lagu nuugo oo lagu sifeeyo, kookaha calcined ee buuxa waxaa dib u soo nooleeyay habka dib u soo kabashada kuleylka.

Marka hore, habka adsorption ee coke calcined ayaa la darsay, iyo saamaynta heerkulka adsorption, fiirsashada qiiqa garoonka, xawaaraha meel bannaan iyo size qayb ka mid ah kookaha calcined on saamaynta adsorption ee kookaha calcined ayaa la falanqeeyay.Natiijooyinka cilmi-baaristu waxay muujinayaan in xadiga qiiqa garoonka ee lagu xayaysiiyaa kookaha la kariyey ay korodho marka ay korodho fiirsashada qiiqa garoonka.Xawaaraha booska hooseeya, heerkulka hooseeya, iyo cabbirka walxaha yaryar ayaa dhammaantood faa'iido u leh ku-dhejinta qiiqa birta ee kookaha la kariyey.Thermodynamics adsorption of coke calcined ayaa la darsay, taas oo muujisay in habka adsorption uu ahaa xayeysiis jireed.Dib u noqoshada isotherm-ka xayeysiinta waxay muujineysaa in habka xayeysiinta uu waafaqsan yahay isla'egta Langmuir.

Marka labaad, dib-u-soo-noolaynta kululaynta iyo soo kabashada uumiga ee kookaha calcined ee saturated.Saamaynta heerka qulqulka gaaska side, heerkulka kulaylka, qadarka kookaha kakooban ee saturated iyo waqtiyada dib u soo kicinta ee hufnaanta dib u soo kabashada ee kookaha calcined ayaa la baadhay siday u kala horreeyaan.Natiijooyinka tijaabada ah waxay muujinayaan in marka heerka socodka gaaska side uu kordho, heerkulka kulaylku kordho, iyo qadarka kookaha ka dib marka la isku daro calcining saturated, waxay faa'iido u leedahay hagaajinta waxtarka dib u soo kabashada.Condensate oo nuugo gaaska dabada dib-u-soo-nooleynta, iyo heerka soo kabashada ayaa ka sarreeya 97%, taas oo muujinaysa in uumiga iyo habka nuugista ay si fiican u soo kaban karto bitumen ee gaasta dabada dib u soo kabashada.

Ugu dambeyntii, saddexda hab ee ururinta gaaska, nadiifinta iyo dib-u-soo-nooleynta ayaa loo qaabeeyey, natiijooyinka naqshadeynta ayaa la hirgeliyaa.Natiijooyinka codsiga warshaduhu waxay muujinayaan in hufnaanta sifaynta ee qiiqa asphalt iyo benzo (a) pyrene ay gaadho 85.2% iyo 88.64%, siday u kala horreeyaan, marka nadiifiyaha loo isticmaalo in lagu qabto oo lagu nadiifiyo qiiqa daamurka ee kala firidhsan iyo kuwa aan habaysan lahayn.Heerarka qiiqa asphalt iyo benzo (a) pyrene ee ka soo baxa nadiifiyaha waxay ahaayeen 1.4mg/m ~ 3 iyo 0.0188μg/m ~ 3, iyo qiiqa 0.04kg/h iyo 0.57×10~(-6)kg /h, siday u kala horreeyaan.Waxa ay gaadhay heerka sare ee dheecaanka dhamaystiran ee wasakhowga hawada GB16297-1996.
