1. Lub cev muaj zog
Cov yam ntxwv tseem ceeb: tsis muaj xim, tsis muaj ntxhiab tsw nrog cov dej solubility tsawg heev. Nws qhov ceev yog qis dua li huab cua, nrog rau qhov sib txheeb ze ntawm 0.554 piv rau huab cua.
Lub xeev hloov pauv: Boiling point -161.5 degree, melting point -183 degree.
2. Cov khoom siv tshuaj
Kev ruaj ntseg: Nws tsis hnov mob nrog cov kua qaub uas muaj zog, muaj zog alkalis lossis muaj zog oxidants zoo li potassium permanganate ntawm chav tsev kub.
Cov tshuaj tiv thaiv combustion: Nws kub hnyiab nrog cov nplaim daj daj, ua cov pa roj carbon dioxide thiab dej, nrog tus nqi calorific ntawm 882.0 kJ / mol.
Hloov cov tshuaj tiv thaiv: Nws reacts maj mam nrog halogens xws li chlorine nyob rau hauv lub teeb los tsim chloromethane mus txog carbon tetrachloride.
Lwm cov tshuaj tiv thaiv: Nws tuaj yeem raug thermally decomposed rau hauv cov pa roj carbon thiab hydrogen ntawm qhov kub thiab txias, los yog tsim cov pa roj carbon monoxide thiab hydrogen ntawm chav hloov pauv.
3. Qhov chaw thiab kev npaj
Cov peev txheej ntuj: Nws suav rau 70% -90% ntawm cov pa roj ntsha, thiab tseem muaj nyob hauv biogas thiab thee mine gas.
Kev npaj hauv chav kuaj: Npaj los ntawm cua sov anhydrous sodium acetate nrog dej qab zib txiv qaub.
4. Cov ntawv thov tseem ceeb
Roj: Raws li cov khoom tseem ceeb ntawm cov roj ntsha, nws tau siv dav hauv kev lag luam thiab kev lag luam.
Cov khoom siv tshuaj lom neeg: Siv los tsim acetylene, hydrogen, carbon dub, formaldehyde, hluavtaws ammonia thiab chlorinated hydrocarbons.
Daim ntawv thov ib puag ncig: Methane rov ua haujlwm hauv cov haujlwm biogas txo cov nyhuv tsev cog khoom, vim nws cov nyhuv tsev cog khoom yog 25 npaug ntawm carbon dioxide.
5. Kev ceev faj txog kev nyab xeeb
Kev pheej hmoo tawg: Kev tawg tuaj yeem tshwm sim thaum nws cov ntsiab lus hauv huab cua nce mus txog 5% -15.4% ib zaug raug rau txim.
Kev phom sij rau kev noj qab haus huv: Cov ntsiab lus siab ntawm methane ua rau tsis muaj oxygen, ua rau kiv taub hau thiab ua tsis taus pa.
Nrog rau cov khoom siv tshuaj ruaj khov thiab kev siv ntau yam, methane ua cov khoom tseem ceeb rau kev hloov hluav taws xob thiab kev tsim tshuaj lom neeg.
Cim npe nrov: Tuam Tshoj siab concentration methane manufacturers, lwm tus neeg, Hoobkas
