Ndedzipi nzira mbiri dzekuita maleic anhydride?
Kuenzanisa kwenzira mbiri dzekuita
Tekinoroji dzekugadzira dze Maleic Anhydride Zvinonyanya kusanganisira tekinoroji ye oxidation ye benzene uye n-butane oxidation maererano nenzira dzezvinhu zvakagadziriswa. Kuenzanisa kwe benzene oxidation ne n-butane oxidation maererano nemaitiro:
Kufamba kwemaitiro: Nzira mbiri idzi dzine kufamba kwemaitiro kwakafanana; musiyano mukuru uri mu catalyst.
Kukura kwetekinoroji: Tekinoroji dzese dzakura. Nzvimbo dzekugadzira dzekunze dzinonyanya kushandisa nzira ye n-butane, nepo nzvimbo dzekugadzira dzemuno dzichinyanya kushandisa nzira ye benzene.
Nzira ye n-butane senzira yekuvandudza: Kubva pakuona kwekuvandudzwa kwetekinoroji yekune dzimwe nyika, indasitiri yepasi rose ye maleic anhydride inonyanya kushandisa nzira ye n-butane. Nokudaro, huwandu hwesimba rekugadzira rinobva ku n-butane huri kuramba huchiwedzera. Zviwanikwa zve n-butane zvekune dzimwe nyika zvakawanda, uye 100% yezvivakwa zvitsva zvekugadzira zvinoshandisa nzira ye n-butane. Maitiro ekugadzira n-butane muEurope akaverengera 89% yesimba rekugadzira maleic anhydride parizvino, pakutanga achipedzisa shanduko yenzira yezvinhu zvisina kugadzirwa. MuChina, nekuda kwehuwandu hwakawanda hwezviwanikwa zve benzene zvinobva muzvigadzirwa zvemakemikari emarasha, maitiro ekugadzira maleic anhydride akavakirwa ku benzene anoverengera 90% yesimba rese rekugadzira maleic anhydride munyika.
