atural bitumen: Petroleum yog nyem los ntawm lub ntiaj teb crust rau lub sij hawm ntev nyob rau hauv cov xwm thiab tuaj mus rau hauv kev sib cuag nrog huab cua thiab noo noo. Nws lub teeb roj cov ntsiab lus maj mam evaporates, thiab cov roj av bitumen tsim los ntawm concentration thiab oxidation feem ntau tov nrog ib qho kev faib ua feem ntawm cov zaub mov. Ntuj bitumen yuav muab faib ua pas dej bitumen, pob zeb bitumen, submarine bitumen, roj shale, thiab lwm yam raws li ib puag ncig nyob rau hauv uas nws yog tsim.
Pob zeb bitumen yog ib yam khoom zoo li bitumen muab los ntawm cov roj av thaum ub tau nkag mus rau hauv cov pob zeb tawg, thiab tom qab ntau pua lab xyoo ntawm deposition, hloov, adsorption, thiab fusion, nyob rau hauv kev sib xyaw ua ke ntawm tshav kub zog, siab, oxidation, catalysts, kab mob, thiab lwm yam.
Pob zeb bitumen hloov bitumen siv pob zeb bitumen ua ib qho kev hloov kho thiab sib xyaw nrog matrix bitumen raws li ib qho kev sib xyaw ua ke. Hloov kho bitumen yog tsim los ntawm cov txheej txheem xws li kev sib xyaw, shearing, thiab kev loj hlob. Nws yog hu ua NMB.
Pob zeb bitumen hloov kho bitumen sib tov yog ib qho sib tov uas tsim los ntawm "ntub" txheej txheem raws li "pob zeb bitumen hloov bitumen" los yog ib tug sib tov tsim los ntawm ib tug "qhuav" txheej txheem raws li "pob zeb bitumen hloov kho".
"Dry method" txheej txheem "Dry method" txheej txheem txhais tau hais tias tom qab nchuav cov ntxhia cov ntaub ntawv rau hauv lub lauj kaub sib tov, lub pob zeb bitumen hloov kho yog ntxiv rau lub lauj kaub sib tov thiab tov nrog cov khoom ntxhia qhuav rau ib lub sijhawm, thiab tom qab ntawd muab txau rau hauv lub matrix bitumen rau ntub Bitumen sib tov txheej txheem.
"Wet method" txheej txheem "Wet method" txheej txheem txhais tau hais tias cov pob zeb bitumen hloov kho thiab lub hauv paus bitumen ntawm qhov kub thiab txias yog thawj zaug sib tov, sheared, thiab tsim rau hauv cov pob zeb tiav lawm hloov bitumen, thiab tom qab ntawd tsuag tsuag rau hauv lub lauj kaub sib tov kom tov nrog. cov ore. Bitumen mix txheej txheem.
