Indlela ukusuka methane, iasithilini

Ukuze ufumane methane of iasithilini, kuyimfuneko ukuba ukuqhuba indlela dehydrogenation. Ngaphambi kokuqalisa uhlolo, ukuhlalutya ezinye hydrocarbon ethile.

Iimpawu ze iasithilini

Le into sukube, nto leyo ummeli yokuqala udidi hydrocarbon ezihluthiyo (alkynes). Kuyinto elula komoya, ayiqondakali enyibilikayo emanzini. Ezinto formula C ₂ H _2, eqhelekileyo yonke iklasi SPN ₂ n-2. Iasithilini ithathwa imichiza esebenzayo, ngaphandle umonakalo omkhulu kakhulu. Ukwenzela ukuphepha iimeko zonxunguphalo, igcinwe kwiziphathi zentsimbi etywiniweyo, esongeza kulo namalahle.

Ukufumana evela alkanes

Phezu yokubola methane iasithilini ifunyenwe. Le yokusabela chemical lwenziwa kusetyenziswa leyo iza kwenzeka ngendlela lobushushu ephakamileyo. Le nkcazelo ukuqala limi kwiklasi yokuqala paraffins ummeli. Xa dehydrogenation, kongezwe iasithilini, hydrogen usenziwa.

Ukuphendula umbuzo malunga nendlela ukusuka methane, iasithilini, inxaki reaction imelwe ifomu:

2SN4 = C2H2 + 3H2

indlela khabhayithi

Omnye sivela methane okanye iasithilini njengoko izinto ukuqala ukuthatha carbide calcium. Le inkqubo ke ithabatha indawo phantsi kweemeko ngumsindo. Xa indlela ikhalsiyam khabhayithi ngamanzi ezikhandelwa kuphela iasithilini, kodwa calcium hayidroksayidi (islaked). Iimpawu kuya kumpompoza inkqubo yemichiza gas ngendaleko (umsondlo), kwaye ukutshintsha ngokudibanisa ਫ਼ੂਜਿੰਗ inkqubo kwi umbala obomvu ngombala yesisombululo.

Xa ofaka izinto yokuqala a khabhayithi yobugcisa ukuba ubumdaka ezahlukeneyo, ivumba waphawula ngexesha basabela. Wachaza phambi kwesi iimveliso zisabela neegesi ezifana enetyhefu njengoko phosphine, hydrogen emanzini.

petroleum nokuqhekeka

Okwangoku, awukwazi nje uphume methane, iasithilini. Indlela ephambili mveliso zokukhokhela mmeli alkyne luthathwa ng (cleavage) of hydrocarbon. Ukuba methane kwamkela iasithilini, iindleko zamandla ziya kuba ncinci. Ukongeza kwiincwadi engaxabisi kakhulu yaye zifumaneka lula ekrwada, obu bugcisa utsale abavelisi hydrocarbon elula kwezixhobo zobuchwepheshe ezisetyenziswa dehydrogenation methane.

Kukho iinguqulelo ezimbini senkqubo kwemichiza efanayo. Indlela yokuqala isekelwe odlulayo methane ngokusebenzisa i electrode, eshushu ukuya 1600 degrees Celsius. Le ndlela iquka ucima imveliso isiphumo. Okwesibini ATHUNYIWEYO dehydrogenation methane ukuba ukuvelisa iasithilini kubandakanya ukusetyenziswa kwamandla, apho iveliswa ukutshiswa kwenxenye ye alkyne.

Nesilinda eziqulathe iasithilini, asikwazi kuxhotyiswa kwemithambo nobhedu, njengenxalenye yeBronzi iqulethe yobhedu. Impefumlelwano intsimbi kunye isivuno iasithilini ihamba netyuwa Uyadubula.

isiphelo

Iasithilini njengangoku lusetyenziselwa kwiinkalo mveliso ezahlukeneyo. Kuyinto exabisekileyo ekrwada ezibonakalayo ukuze Yindibanisela ethanol, iiplastiki, rubbers, acetic acid. Representative kule klasi ibango alkynes ukusika nokudibanisa iintsimbi zesinyithi, njengokuba ukukhanya okuqaqambileyo kwi zalapho zokukhanya ngamnye.

Ngenxa yokuba kuyondelelaniswe iasithilini iqhutywa iziqhushumbisi asetyenziswe ngohlobo detonators. Igcwala abasabela ngayo alkyne oksijini emoyeni elifana neli anjengedangatye olomeleleyo. Of ixabiso olulinganayo olu shishino kwemichiza methane. Ngaphandle isicelo wayo njengoko eqala ekuveliseni iasithilini eziphathekayo, oko Lonakele kukuninzi njenge ezizizembiwa zendalo kushishino amafutha kulo. Xa itshiswe zabelwe imali ethe ubushushu.
