Ziziphi iindlela ezimbini zenkqubo ye-anhydride ye-maleic?
Ukuthelekiswa kweendlela ezimbini zenkqubo
Iitekhnoloji zemveliso ze I-Maleic Anhydride ikakhulu ziquka ubuchwepheshe be-benzene oxidation kunye ne-n-butane oxidation ngokweendlela zezinto eziluhlaza. Uthelekiso lwe-benzene oxidation kunye ne-n-butane oxidation ngokwenkqubo:
Ukuhamba kwenkqubo: Ezi ndlela zimbini zineendlela ezifanayo zokuhamba kwenkqubo; umahluko ophambili ukwi-catalyst.
Ukuvuthwa kobuchwepheshe: Zombini ezi teknoloji zivuthiwe kakhulu. Izakhiwo zemveliso zangaphandle zisebenzisa ikakhulu indlela ye-n-butane, ngelixa izakhiwo zemveliso zasekhaya zisebenzisa ikakhulu indlela ye-benzene.
Indlela ye-n-butane njengendlela yophuhliso: Ngokwembono yophuhliso lwetekhnoloji yangaphandle, ishishini le-maleic anhydride lehlabathi ngokubanzi lisebenzisa inkqubo ye-n-butane. Ke ngoko, umlinganiselo wamandla emveliso asekelwe kwi-n-butane uyaqhubeka nokwanda. Izixhobo ze-n-butane zangaphandle zininzi, kwaye i-100% yezixhobo zemveliso ezisandula ukwakhiwa zisebenzisa indlela ye-n-butane. Inkqubo yemveliso ye-n-butane eYurophu ithathe i-89% yamandla emveliso ye-maleic anhydride yangoku, okokuqala igqibezela utshintsho lwendlela yezinto eziluhlaza. E-China, ngenxa yezixhobo ezininzi ze-coking benzene ezivela kwiimveliso zeekhemikhali zamalahle, inkqubo yemveliso ye-maleic anhydride esekwe kwi-benzene ithatha i-90% yamandla emveliso ye-maleic anhydride yelizwe liphela.
