Li-hydrocarbon (HCs) ke eng?

Li-hydrocarbon ke metsoako ea lintho tse phelang e entsoeng ka mefuta e 'meli feela ea liathomo - khabone le haedrojene. Li-hydrocarbon li hlaha ka tlhaho 'me li theha motheo oa oli e tala, khase ea tlhaho, mashala le mehloli e meng ea bohlokoa ea matla. Li ka cha haholo 'me li hlahisa carbon dioxide, metsi le mocheso ha li chesoa. Ka hona, li-hydrocarbon li sebetsa hantle haholo e le mohloli oa mafura. Ka tloaelo, li-hydrocarbon ke likhase tse se nang 'mala tse nang le monko o fokolang haholo.

 

Mefuta e mene ea li-hydrocarbon ke efe?

Li-hydrocarbon li ka ba le meaho e bonolo kapa e rarahaneng haholo 'me ka kakaretso li ka aroloa ka lihlopha tse' nè tse nyenyane, e leng li-alkanes, li-alkenes, li-alkynes le li-hydrocarbon tse nkhang hamonate.

Tšebeliso ea li-hydrocarbon ke efe?

• Li-hydrocarbon tse kang propane le butane li sebelisetsoa merero ea mafura a khoebo ka mokhoa oa Liquefied Petroleum Gas (LPG). Benzene, e 'ngoe ea li-hydrocarbon tse bonolo ka ho fetisisa tse nkhang hamonate, e sebetsa e le thepa e tala bakeng sa ho kopanya meriana e mengata ea maiketsetso.
• Tsena di sebediswa e le mohlodi wa mafura o ka tukang, mohlala: Methane e leng karolo ya kgase ya tlhaho.
• Peterole, mafura a jete le naphtha ke li-hydrocarbon tsa aliphatic tse sebelisoang haholo liindastering tse fapaneng.
• Metswako ya marulelo a sekontiri kapa sebopeho sa tsela le di-preservative tsa lehong ke mefuta e fapaneng ya di-hydrocarbon.
• Tšebeliso ea tsona e le lintho tse seng mafura tse ngata tse kang ethane le propane li fumanoa ho tsoa peteroleng le khase ea tlhaho. Likhase tsena tse peli li ka fetoloa ethylene le propylene.
• Li-hydrocarbon tse khethehileng tse kang motsoako oa li-isomer tsa benzene, toluene le xylene lia tsebahala 'me tšebeliso ea tsona e phahame haholo.
• Li-hydrocarbon tse fumanehang ka tlhaho li fumanoa linotšing tsa Brazil tse se nang ho hlaba tse sieang monko o ikhethang oa hydrocarbon le ho thusa ho khetholla leloko ho bao e seng leloko.

 

Li-refrigerant tsa hydrocarbon ke eng?

 Li-refrigerant tsa hydrocarbon ke tse tsejoang e le 'li-refrigerant tsa tlhaho.' Ha li na chefo, ha li fokotse O-zone, 'me li na le Bokhoni bo tlase haholo ba ho Futhumala ha Lefatše. Ho feta moo, ke tse ling tsa li-refrigerant tse sebelisang matla hantle lefatšeng kajeno.

 Nako ea li-refrigerant tsa khase tse nang le fluorine e ea fela 'me kaofela li tla felisoa lefatšeng ka bophara lilemong tse mashome tse tlang. Li-refrigerant tsa hydrocarbon li tla nka sebaka sa tsona. Li-hydrocarbon li se li tumme haholo Europe le Asia 'me li fumanoa li sebelisoa haholo lits'ebetsong tsa sehatsetsing. Joalo ka tloaelo, United States e saletse morao lefatšeng ka bophara ha ho tluoa li-refrigerant tse ling ... empa re fe nako 'me u tla qala ho bona li-hydrocarbon li hlaha haholoanyane ho pholletsa le US.

 Mehlala e meng ea sesebelisoa sa ho pholisa sa hydrocarbon ke ena:

 R-290(Propane)

 R-600a(Isobutane)

 R-1150(Ethene/Ethylene)

 R-1270(Propene/Propylene)

 R-170(Ethane)

 Metswako le metswako e fapaneng ya dihlahiswa tse boletsweng ka hodimo.
