I-Biodiesel, okudingeka ukwazi ngedizili yemifino
Ikusasa lokuhamba okusimeme mancane amathuba okuba lidlule esixazululweni esisodwa: izinsiza ezizosetshenziswa ziningi, ezivela ezinhlelweni ezahlukene. ukudonsa kagesi al igesi yemvelo, akekho kubo okwamanje ongahlangabezana nazo zonke izimfuneko ngokwawo futhi amboze kangcono konke ukusetshenziswa.
Phakathi kwalezo ezibonakala sengathi azinakiwe muva nje i-biodieseleyayihamba phambili kwezinye izindlela ezingasetshenziswa esikhundleni sikaphethiloli eminyakeni embalwa edlule, kodwa okungakhulunywa kakhulu ngayo namuhla, nakuba isivele ikhona kudizili esivame ukuwusebenzisa.
Yini i-biodiesel
Igama elithi biodiesel lichazwa ngokuthi uphethiloli otholwe yizinqubo zamakhemikhali kusuka uwoyela wemifino njenge-rapeseed, ubhekilanga, amafutha okuthosa asetshenzisiwe nokunye. Umphumela uba uketshezi olune-viscosity efana nophethiloli we-diesel, ingxubevange kunoma iyiphi ingxenye enezici zendabuko nezifanayo futhi isivele isetshenziswa njengesengezo kuphethiloli ojwayelekile wedizili ukuyigcizelela. ukuthambisaikakhulukazi uma i-base diesel fuel inokuqukethwe kwesulfure encishisiwe.
Umehluko omkhulu kunayo yonke amandla aphezulu okuqedwa okudinga ukubuyekezwa kwezingxenye ezithile zenjini. Eqinisweni, yizinjini zakamuva kuphela eziklanyelwe ukusebenzisa i-biodiesel. 100%, futhi kulabo abadlule kuyafiseleka ukuthi bangeqi ku-30%. Ukusetshenziswa kwayo okwamanje kukhawulelwe kuphethiloli. B7 noma B10, isifinyezo esibonisa ukusetshenziswa kwaso ngamaphesenti asukela ku-7 kuya ku-10%.
Izinzuzo zemvelo
Inzuzo enkulu ye-biodiesel ilele kumsuka wayo: iqiniso lokuthi iphuma emithonjeni evuselelekayo lenza lonke uchungechunge lokuhlinzeka lusebenze kahle. Inani le-biodiesel emjikelezweni walo liyancipha ngenani elifanayo 50% Ukukhishwa kwe-CO2 emkhathini kufana ncamashi ne-biogas, okukhishelwa yona isikhutha isizukulwane kuze kube yilapho ishiswa, ilinganiswa ingxenye yalokho okumuncwa izitshalo eziphilayo ezizosetshenziselwa ukukhiqizwa kwayo.
Imikhawulo ye-Biodiesel
I-Biodiesel nayo inokulinganiselwa okuthile, ngisho nokuncane. Uma isetshenziswa, ukukhishwa kwe-CO2 kuyathuthukiswa futhi ukukhishwa kwe-carbon dioxide kuyehla. i-nitrogen oxidesezixazululwa "ezansi nomfula" ngokuphazamisa izinjini nokusebenzisa izihlungi nama-catalysts kumagesi okukhipha umoya, okudingekayo futhi kuphethiloli we-diesel evamile.
I-GLI izithiyo ezinkulu ekusatshalalisweni kwawo njengenye indlela yophethiloli wedizili kungokwezomnotho, kwezepolitiki nezenhlalo. Eqinisweni, ukuze kuhlangatshezwane nesidingo somhlaba wonke se-biodiesel, umuntu kufanele acabange ngomsebenzi othile wezolimo ozokwenziwa ngezindleko ze isidingo sokudlaikakhulukazi ezindaweni ezintula kakhulu amathuba, futhi okwamanje akwenzeki ukunikeza isivuno esikhulu sokukhiqiza uphethiloli, noma ngabe lokhu kunomthelela omuhle kakhulu kwezemvelo.
HVO, ngenye indlela
Isihlobo esikude se-biodiesel yilokho okubizwa Amafutha emifino ane-hydrogen o HVO, uwoyela wemifino ofakwe emanzini. Kuwuphethiloli osezingeni eliphezulu otholakala kuwoyela ongcolile, uwoyela we-rapeseed, amafutha esundu namafutha ezilwane. Yehlisa ngokuphelele ukukhishwa kwe-CO, okungase kwehliswe. 90%Kodwa-ke, kuye kwavela ukukhathazeka ngokuziphatha njengoba izinkampani eziyisebenzisayo, njenge-Eni, eyisebenzisa ku-Diesel + yazo, iwuthola emafutheni esundu akhiqizwa ngezinqubo ezinkulu zokugawulwa kwamahlathi ngakho-ke kubhekwa njengamanje. azinzile.
