Joaloka k'hemik'hale e sebelisoang haholo, methanol e sebelisoa ho hlahisa mefuta e mengata e fapaneng ea lihlahisoa tsa lik'hemik'hale, tse kang li-polymers, solvents le libeso. Har'a tsona, methanol ea malapeng e entsoe haholo ka mashala, 'me methanol e tsoang linaheng tse ling e arotsoe haholo ka mehloli ea Iranian le mehloli e seng ea Iranian. Ts'ebetso ea lehlakore la phepelo e ipapisitse le potoloho ea thepa, keketseho ea phepelo le phepelo e 'ngoe. Joalo ka karolo e kholo ka ho fetesisa ea methanol, tlhoko ea MTO e na le tšusumetso e kholo ho potlakiso ea theko ea methanol.

1.Methanol bokhoni ba theko ntlha

Ho ea ka lipalo-palo tsa data, qetellong ea selemo se fetileng, matla a selemo le selemo a indasteri ea methanol e ne e ka ba lithane tse limilione tse 99.5, 'me kholo ea selemo le selemo e ntse e fokotseha butle-butle. Bokhoni bo bocha bo reriloeng ba methanol ka 2023 bo ne bo ka ba lithane tse limilione tse 5, 'me matla a macha a ne a lebelletsoe ho ikarabella bakeng sa 80%, ho fihlela lithane tse ka bang limilione tse 4. Har'a bona, karolong ea pele ea selemo sena, Ningxia Baofeng Phase III e nang le matla a selemo le selemo a lithane tse limilione tse 2,4 e na le monyetla o moholo oa ho kenya tlhahiso.
Ho na le lintlha tse ngata tse khethollang theko ea methanol, ho kenyelletsa phepelo le tlhoko, litšenyehelo tsa tlhahiso le maemo a moruo a lefats'e. Ho feta moo, theko ea oli e tala e sebelisoang ho hlahisa methanol e tla ama theko ea bokamoso ba methanol, hammoho le melao ea tikoloho, tsoelo-pele ea theknoloji le liketsahalo tsa geopolitical.
Ho feto-fetoha ha theko ea bokamoso ba methanol le hona ho hlahisa maemo a itseng. Ka kakaretso, theko ea methanol ka Hlakubele le Mmesa selemo se seng le se seng e theha khatello, eo ka kakaretso e leng nako e seng ea tlhokeho. Ka hona, ntlafatso ea semela sa methanol le eona e qala butle-butle nakong ena. Phuptjane le Phupu ke tsona tse ngata haholo ka linako tsa selemo tsa pokello ea methanol, 'me theko ea nako e sa sebetseng e tlase. Methanol e oele haholo ka Mphalane. Selemong se fetileng, ka mor'a Letsatsi la Sechaba ka October, MA e ile ea bula holimo 'me ea koala tlaase.

2.Analysis le ponelopele ea maemo a marakeng

Bokamoso ba Methanol bo sebelisoa ke liindasteri tse fapaneng, ho kenyeletsoa matla, lik'hemik'hale, polasetiki le masela, 'me li amana haufi-ufi le mefuta e amanang le eona. Ho phaella moo, methanol ke karolo ea bohlokoa ea lihlahisoa tse ngata tse kang formaldehyde, acetic acid le dimethyl ether (DME), tse nang le mefuta e mengata ea lisebelisoa.

Mmarakeng oa machaba, Chaena, United States, Europe le Japane ke tsona tse sebelisang methanol e kholo ka ho fetisisa. China ke mohlahisi e moholo ka ho fetisisa le moreki oa methanol, 'me 'maraka oa eona oa methanol o na le tšusumetso ea bohlokoa' marakeng oa machaba. Tlhokahalo ea China ea methanol e tsoetse pele ho hola lilemong tse 'maloa tse fetileng, e leng ho phahamisa theko ea mmaraka oa machabeng.

Ho tloha ka Pherekhong selemong sena, ho se lumellane pakeng tsa phepelo ea methanol le tlhoko e bile nyane, mme mojaro oa khoeli le khoeli oa MTO, acetic acid le MTBE o eketsehile hanyane. Kakaretso ea ho qala pheletsong ea methanol ea naha e fokotsehile. Ho latela lipalo-palo, matla a khoeli le khoeli a tlhahiso ea methanol a amehang ke lithane tse limilione tse 102, ho kenyeletsoa lithane tse 600000 / selemo tsa Kunpeng Ningxia, lithane tse 250000 / selemo tsa Juncheng ho Shanxi le lithane tse 500000 / selemo tsa Anhui Carbonxin ka Hlakola.
Ka kakaretso, ka nako e khuts'oane, methanol e ka 'na ea tsoela pele ho feto-fetoha, ha 'maraka oa libaka le' maraka oa disk o sebetsa hantle haholo. Ho lebeletsoe hore phepelo ea methanol le tlhokahalo li tla tsamaisoa kapa li fokotsehe kotareng ea bobeli ea selemo sena, 'me phaello ea MTO e lebelletsoe ho lokisoa holimo. Ha nako e ntse e ea, phaello ea phaello ea yuniti ea MTO e lekanyelitsoe mme khatello ea phepelo ea PP le tlhoko e kholo nakong e mahareng.
