Uma kuqhathaniswa namazwe angaphandle, imakethe kaphethiloli ye-ethanol inkulu, futhi njengamanje ilawulwa yi-biomass ethanol. Amalahle -to -ethanol kulindeleke ukuthi abe ukhiye olandelayo wokuthuthukiswa komkhakha olandelayo wamakhemikhali wamalahle ngemuva kukawoyela wokwenza amalahle, amalahle -kuya -gesi, amalahle -to -olefin, namalahle -to -ethylene glycol, kanye nokuncintisana ngqo. nge-biomass ethanol nenzuzo yayo enkulu yezindleko.
Ukubuka okubalulekile
Imakethe kaphethiloli yezwe lami inesikhala esikhulu, futhi ngokuhamba kwesikhathi, inegebe elicishe libe yizigidi eziyisi-9.4. I-ethanol yesibaseli ingenza uphethiloli wanele, ngesikhathi esifanayo, ukumelana nokuqhuma okuhle, futhi iye yakhuthazwa kabanzi emhlabeni jikelele. Ngo-2016, ukukhiqizwa kwe-ethanol kaphethiloli kwezwe lami kwakungamathani ayizigidi ezingu-2.6 kuphela, uma kuqhathaniswa ne-United States yamathani ayizigidi ezingu-42.66 kanye namathani ayizigidi ezingu-17.44 eBrazil, eyayinendawo enkulu yokuthuthukiswa. Esikhathini esimaphakathi, “Uhlelo Lweminyaka Emihlanu Lweminyaka Emihlanu” lwe-Energy Bureau lwahlongoza ukuthi ngo-2020, ukukhiqizwa kwe-ethanol kaphethiloli ezweni lami kwaba amathani ayizigidi ezi-4, okuwukunyuka ngo-54% kunokwenyuka kwamanje. I-Ethanol idinga igebe. Ukwengeza, amanani entengo ye-ethanol yokungenisa kanye nokukhuthazwa kokuhlolwa kophethiloli we-ethanol kuzovumela isidingo se-ethanol yasekhaya.
Inzuzo yezindleko ze-ethanol kaphethiloli wamalahle isobala, nezindleko zamayuan/ton angu-300 kuya ku-800 yuan/ton kunezindleko ze-ethanol ye-glycotic. Imizila emibili yenqubo ye-ethanol yokuhlukanisa i-ethanol kaphethiloli kanye namalahle kuya ku-ethanol, ibale izindleko ze-biomass ethanol kumayuan angu-4700-5600 (isizukulwane se-G1 4709 yuan/ton, isizukulwane se-G1.5 5275 yuan/ton, isizukulwane se-G2 esingu-5588 yuan/ ithani); kuyilapho izindleko ze-ethanol ezenziwe ngamalahle ngokuvamile ziphakathi kuka-4000-4200 yuan (igesi yokwenziwa ye-IFP eqondisa i-hydrogen eqabulayo engu-4071 yuan/ton, i-Portal chemical acetic acid i-hydrogenation eqondile ye-4084 yuan/ton, i-hydrogen hydrogen acid ester ester hydrogenation enwetshiwe 4201, medium yuan/ ubuchwepheshe obuncibilikayo i-hydrogen acetate 4104 yuan/ton), ngisho nangemva kokucabangela izici ezifana noxhaso lwe-ethanol yokudla kanye nokwehliswa kwentela yokusetshenziswa, amalahle -to -ethanol asenenzuzo enkulu yezindleko, nomehluko wezindleko okungenani ongaba ngu-300 yuan/ton. Isilinganiso esiphezulu singafinyelela cishe ku-800 yuan/ton.
Uxhaso lwe-biomantic ethanol lwehlile, futhi i-ethanol eyenziwe ngamalahle kulindeleke ukuthi iqhamuke ngenzuzo yezindleko. Esikhathini esizayo, i-biomass ethanol ingase ibhekane nezingozi ezilandelayo: (1) Uxhaso lwezimali luye lwaqhubeka nokwehla, futhi uxhaso lwe-ethanol lokusanhlamvu lwehle lusuka ku-1883 yuan/ton ngo-2005 kuya ku-2016 ngaphandle koxhaso, futhi inzuzo ingase yonakale; (2) Umshayeli wenguquko yezokulima -ehlangothini lokushintsha ummbila Ukuze kususwe ummbila, intengo yommbila izonyusa izindleko ze-ethanol yommbila uma ummbila ungaphansi. Ngokuphambene, i-coal-to-ethanol isenenzuzo yokuncintisana ngisho nangaphandle komxhaso. Ngaphezu kwalokho, isilinganiso samandla okukhiqiza we-ethanol yezinto eziphilayo kanye ne-ethanol eyenziwe ngamalahle esikhathini esizayo sicishe sibe ngu-3: 1. Sahlulela ukuthi ukuncintisana phakathi kwezinkampani zamalahle kuya ku-ethanol ngeke kushube kakhulu, futhi kulindeleke ukuthi kuthathelwe indawo i-ethanol enkulu yezinto eziphilayo. ngenzuzo yezindleko.
