Cov pa roj carbon yog ib qho nonmetallic caij nyob rau hauv IVA pawg ntawm lub sijhawm thib ob bai.Latin rau Carbonium, txhais tau tias "coal, charcoal".Cov cim Suav "carbon" yog tsim los ntawm charcoal "carbon" thiab lo lus pob zeb, los ntawm "carbon" suab.Cov pa roj carbon monoxide yog cov khoom siv ntau heev, dav dav nyob rau hauv ntau hom hauv Chemicalbook roj thiab lub ntiaj teb pob zeb.Cov pa roj carbon tau paub ntev thiab tau siv, thiab cov duab sib txuas ntawm cov pa roj carbon, cov muaj sia, yog qhov tseem ceeb rau lub neej.Cov pa roj carbon yog ib qho chaw ua yeeb yaj kiab ntawm npua hlau, hlau thiab hlau.Cov pa roj carbon yog biologically thiab kev ua lag luam tseem ceeb molecule uas siv cov tshuaj siv nws tus kheej los ua cov lej sib txuas.Feem ntau cov molecules hauv cov khoom muaj sia muaj carbon.
Cov khoom siv tshuaj
Dub hmoov los yog granular porous crystals.Bushing point 4827 ℃, 3652 ℃ Sublimation, txheeb ze ntom txog 1.8-2.1, kev ua tau zoo cuam tshuam txog 0.0.45.
siv
(1) Kev ua kom huv, xws li siv cov pa roj carbon ua kom rov zoo los ntawm cov pa uas muaj cov kuab pa hluav taws xob;Siv cov txheej txheem poweroled ua kom pom kev rau cov huab cua tsis zoo;Lossis siv cov ncauj qhov ncauj qhov ntswg thiab cov khoom nqus dej los tiv thaiv kab mob lom.
(2) Gas sib cais, xws li benzene rov qab los ntawm lub nroog roj, roj av, propane thiab butane rov qab los ntawm cov pa roj, siv rau kev kho cov roj khib nyiab hauv fischer-tropsch synthesis, thiaj li yuav rov qab tau cov hydrocarbons.(3) cov kua theem adsorption xws li hauv kev lag luam qab zib nrog cov tshuaj activated carbon adsorption txoj kev los decolorize qab zib kua, nyob rau hauv cov tshuaj lom neeg kev lag luam nrog activated carbon rau decolorize organic tshuaj, nrog activated carbon purification ntawm cov organic impurities nyob rau hauv lub electroplating da dej, kom ntseeg tau tias lub Qhov tsis zoo ntawm cov hluav taws xob lossis siv rau cov dej khib nyiab.
(4).Catalysts lossis catalysts xws li catalysts siv rau industrial gas desulfurization thiab phosgene ntau lawm, thiab lwm yam. Yog li ntawd, activated carbon yog dav siv nyob rau hauv qab zib, cawv ua, roj refining, tshuaj, reagent, kub, dej purification, ib puag ncig tiv thaiv, rov qab cov kuab tshuaj thiab lwm yam chav thiab lwm yam.
