Cov roj ntsha yog cov sib xyaw ua ke ntawm cov hydrocarbons no. Cov roj muaj feem ntau paraffin hydrocarbons hu ua paraffin -based lub tshuaj paraffinic . Cov piv txwv ib txwm yog qib Pennsylvania cov roj nyoos . Naphthenic-based crudes muaj feem ntau ntawm cycloparaffins hauv cov khoom hnyav.

Ib yam li ntawd, nws tau nug, naphthenic crude roj yog dab tsi?

Naphthenic crude roj muaj feem ntau (los ntawm ntim) napthenes thiab lwm yam ntxhiab hydrocarbons. Lawv feem ntau muaj qis dua API lub ntiajteb txawj nqus, piv txwv li, lawv yog cov hnyav dua. Lawv kuj muaj lwm cov ntaub ntawv suav nrog hlau xws li npib tsib xee, hlau, vanadium, thiab arsenic.

Kuj Paub, dab tsi yog cov roj crude? Roj nyoos yog qhov tshwm sim ib txwm muaj, tsis hloov pauv roj av cov khoom tsim los ntawm cov pa roj carbon hydrocarbon thiab lwm yam khoom siv organic. Ib hom roj fossil, roj nyoos tuaj yeem ua kom zoo dua los tsim cov khoom siv tau zoo xws li roj av, diesel, thiab ntau hom petrochemicals.

Ua kom pom qhov no, cov roj paraffinic yog dab tsi?

cov roj paraffinic , raws li n-alkanes. naphthenic cov roj , raws li cycloalkanes. aromatic cov roj , raws li cov tshuaj tsw qab hydrocarbons (qhov txawv ntawm qhov tseem ceeb cov roj ) Cov ntxhia roj yog ib qho ntawm ntau yam tsis muaj xim, tsis muaj ntxhiab, sib xyaw sib xyaw ntawm alkanes hauv C15 txog C40. Nws tau tsim tawm ntau ntau.

Cov roj nyoos ua los ntawm dab tsi?

Roj Crude yog ib tug sib tov ntawm comparatively volatile kua hydrocarbons (compounds feem ntau ntawm hydrogen thiab carbon ), txawm hais tias nws tseem muaj qee cov nitrogen, leej faj, thiab oxygen. Cov ntsiab lus no tsim ntau yam ntawm cov qauv molecular complex, qee qhov tsis tuaj yeem txheeb xyuas tau yooj yim.
