Kwiminyaka yakutshanje, i-ethanol ye-biofuel iphumelele uphuhliso olukhawulezayo kwihlabathi jikelele. Nangona ilizwe lam linomthamo othile wemveliso kulo mmandla, kusekho umsantsa omkhulu xa kuthelekiswa namazwe ahambele phambili kwezoqoqosho. Ekuhambeni kwexesha, uphuhliso lwe-biofuel ethanol luya kukhuthaza ngcono ukulingana kokutya kunye nemfuno kunye nokuqhubela phambili uphuhliso loqoqosho lwasemaphandleni.
“Ishishini le-ethanol ye-biofuel sele liyindawo entsha yokukhula koqoqosho kunye nenyathelo elibalulekileyo lokuphuhlisa uqoqosho lwasemaphandleni. Imveliso ye-biofuel ye-biofuel yelizwe lam okwangoku imalunga ne-2.6 yezigidi zeetoni, isengumsantsa obalulekileyo xa ithelekiswa namazwe aphuhlileyo, kwaye ukukhuthazwa okungaphezulu kuyafuneka. "U-Qiao Yingbin, ingcali yetekhnoloji yekhemikhali kunye nomphathi wangaphambili weSebe lezeNzululwazi kunye neTekhnoloji yaseSinopec, utshilo kwintlanganiso yonxibelelwano yeendaba ebibanjwe kutshanje.
I-biofuel ethanol inokwenziwa ibe yi-ethanol petroli yezithuthi. Iingcali zoshishino zikholelwa ukuba ukubaluleka kokuphuhliswa kwe-biofuel ethanol kukusombulula iingxaki zezolimo. Kangangeminyaka emininzi, ilizwe lam belinyusa ubunzulu bokuguqulwa kombona kwi-situ, kwaye enye yeendlela zokuphuma kukuphuhlisa i-biofuel ethanol.
Amava amazwe ngamazwe abonisa ukuba uphuhliso lwe-biofuel ethanol lunokuseka ixesha elide, oluzinzileyo kunye neendlela ezilawulekayo zokusetyenzwa kunye nokuguqulwa kweemveliso zezolimo ezininzi, kunye nokuphucula amandla elizwe okulawula imarike yeenkozo. Ngokomzekelo, iUnited States isebenzisa i-37% yemveliso yombona iyonke ukuvelisa i-ethanol yamafutha, egcina ixabiso lombona; IBrazil, ngokuveliswa ngokubambisana kweswekile-yeswekile-ethanol, iqinisekisa ukuzinza kwamaxabiso ommoba wasekhaya kunye neswekile kwaye ikhusela iimfuno zamafama.
"Uphuhliso lwe-ethanol ye-biofuel luncedo ekukhuthazeni ukulungelelaniswa kokutya kunye nemfuno, ukwenza umjikelo olungileyo wemveliso yokutya kunye nokusetyenziswa, ngaloo ndlela kuzinzisa imveliso yezolimo, ukuvula iziteshi zamafama ukunyusa ingeniso, kunye nokuqhuba ukusebenza kakuhle kwezolimo kunye nophuhliso loqoqosho lwasemaphandleni. . Isiseko semizi-mveliso ye-ethanol yamafutha siluncedo ekuvuseleleni uMntla-mpuma. utshilo uYue Guojun, isifundiswa kwiZiko laseTshayina lobuNjineli.
Ngokoqikelelo, imveliso yonyaka yelizwe lam yeenkozo eziziinkozo ezidlulelwe lixesha nangaphezulu kunokuxhasa isikali esithile semveliso ye-biofuel ethanol. Ukongeza, umthamo worhwebo wonyaka wombona kunye necassava kwimarike yamazwe ngamazwe ufikelela kwi-170 yezigidi zeetoni, kwaye i-5% inokuguqulwa ibe malunga ne-3 yezigidi zeetoni ze-biofuel ethanol. Inkunkuma yasekhaya ekhoyo ngonyaka yasekhaya kunye nenkunkuma yamahlathi idlula iitoni zezigidi ezingama-400, i-30% yazo inokuvelisa iitoni ezizigidi ezingama-20 ze-biofuel ethanol. Zonke ezi zibonelela ngesiqinisekiso esithembekileyo semathiriyeli ekrwada yokwandisa imveliso kunye nokusetyenziswa kwe-ethanol ye-biofuel kunye nokuqonda uphuhliso oluzinzileyo.
Akunjalo kuphela, i-ethanol ye-bio-fuel inokunciphisa i-carbon dioxide kunye nokukhutshwa kwe-particulate matter, i-carbon monoxide, i-hydrocarbons kunye nezinye izinto ezinobungozi kwi-exhaust yemoto, ehambelana nokuphucula imeko yendalo.
Okwangoku, imveliso ye-ethanol ye-fuel yehlabathi i-79.75 yezigidi zeetoni. Phakathi kwabo, iUnited States yasebenzisa i-45.6 yezigidi zeetoni ze-ethanol ye-corn fuel, i-accounting ye-10.2% ye-petroli yokusetyenziswa kwayo, yanciphisa i-510 yezigidi zemiphanda ye-oyile ekrwada, yasindisa i-20.1 yeebhiliyoni zeedola, yadala i-42 yezigidigidi ze-GDP kunye ne-340,000 yemisebenzi, kwaye yanda irhafu. I-8,5 yeebhiliyoni zeerandi. I-Brazil ivelisa i-21.89 yezigidi zeetoni ze-ethanol ngonyaka, ngaphezu kwe-40% yokusetyenziswa kwepetroli, kunye nokuveliswa kwamandla e-ethanol kunye ne-bagasse kubangele i-15.7% yobonelelo lwamandla welizwe.
Ihlabathi liphuhlisa ngamandla ishishini le-ethanol ye-biofuel, kwaye i-China injalo. NgoSeptemba 2017, ilizwe lam licebise ukuba ngo-2020, ilizwe liza kufezekisa ngokupheleleyo i-petroli ye-ethanol yezithuthi. Okwangoku, amaphondo ali-11 kunye neengingqi ezizimeleyo kwilizwe lam zenza ulingo lokukhuthazwa kwepetroli ye-ethanol, kunye nokusetyenziswa kwepetroli ye-ethanol kubangela isinye kwisihlanu sokusetyenziswa kwepetroli yesizwe kwangelo xesha linye.
Imveliso ye-biofuel ye-biofuel yelizwe lam imalunga ne-2.6 yezigidi zeetoni, ibalelwa kwi-3% kuphela yetotali yehlabathi, ibeka indawo yesithathu. Eyokuqala neyesibini yi-United States (i-44.1 yezigidi zeetoni) kunye neBrazil (i-21.28 yezigidi zeetoni) ngokulandelelana, nto leyo ebonisa ukuba ishishini lelizwe lam le-biofuel ethanol lisenendawo enkulu yophuhliso.
Emva kweminyaka engaphezu kweshumi yophuhliso kwishishini lelizwe lam le-biofuel ethanol, iteknoloji yesizukulwana sokuqala kunye nese-1.5 kusetyenziswa umbona kunye necassava njengemathiriyeli ekrwada zivuthiwe kwaye zizinzile. imeko.
“Ilizwe lam linenzuzo yokukhokela itekhnoloji ye-biofuel ethanol. Ayinakufikelela kuphela injongo yokusebenzisa ipetroli ye-ethanol ye-E10 kwilizwe lonke ngo-2020, kodwa kunye neteknoloji yokuthumela ngaphandle kunye nezixhobo zokunceda amanye amazwe aseke kwaye aphuhlise ishishini le-ethanol ye-biofuel. Qiao Yingbin uthe.
