Ngiziphi iindlela ezimbili zokwenza i-maleic anhydride?
Ukumadanisa iindlela ezimbili zenqubo
Ithekhnoloji yokukhiqiza I-Maleic Anhydride MAzifaka hlangana i-benzene oxidation kanye ne-n-butane oxidation technologies malungana neendlela zezinto ezisetjenziswako. Ukumadanisa i-benzene oxidation kanye ne-n-butane oxidation ngokuya ngenqubo:
Ukugeleza kwenqubo: Iindlela ezimbili zinokugeleza okufanako; umehluko omkhulu ulele ku-catalyst.
Ukuvuthwa kwethekhnoloji: Zombili ithekhnoloji sele ivuthiwe. Iindawo zokukhiqiza zangaphandle zisebenzisa indlela ye-n-butane, lokha iindawo zokukhiqiza zangaphakathi zisebenzisa indlela ye-benzene.
Indlela ye-n-butane njengendlela yokuthuthukisa: Ngokombono wokuthuthukiswa kwethekhnoloji yangaphandle, ibubulo le-maleic anhydride lephasi loke lithatha khulu ikambiso ye-n-butane. Ngalokho-ke, inani lamandla wokukhiqiza asekelwe ku-n-butane liragela phambili nokwanda. Iinsetjenziswa zangaphandle ze-n-butane zinengi, begodu i-100% yeendawo zokukhiqiza ezisanda ukwakhiwa zisebenzisa indlela ye-n-butane. Ikambiso yokukhiqiza i-n-butane e-Europe sele ibalelwa ku-89% wamandla wokukhiqiza we-maleic anhydride, ekuthomeni ukuqeda ukutjhugululwa kwendlela yezinto ezisetjenziswako. E-China, ngebanga lemithombo eminengi ye-coking benzene evela emikhiqizweni yamakhemikhali yamalahle, ikambiso yokukhiqiza i-maleic anhydride esekelwe ku-benzene ibalelwa ku-90% yamandla wokukhiqiza ama-maleic anhydride welizwe.
