AOG-MAC01 benzene yokhazikika Kutulutsa okosijeni ku chothandizira cha Maleic Anhydride
Kufotokozera Kwachidule:
AOG-MAC01benzene yokhazikika Kutulutsa okosijeni kukhala chothandizira cha Maleic Anhydride Mafotokozedwe Akatundu: AOG-MAC01benzene yokhala ndi malo okhazikika Oxidation kupita ku Maleic Anhydride catalyst taking Oxyde wosakaniza mu chonyamulira chosagwira ntchito, V2O5 ndi MoO3 monga zigawo zogwira ntchito, amagwiritsidwa ntchito Mu okosijeni wa benzene wokhazikika ku maleic anhydride. Chothandizirachi chili ndi Makhalidwe a ntchito yapamwamba, mphamvu yayikulu, 98% - 99% kusintha kwabwino, kusankha bwino ndipo mpaka 90%-95% ya phindu. Chothandizirachi chakhala chikuchiritsidwa ndi pre-activation ndi kukonza nthawi yayitali, nthawi yoyambira yoyambitsa imachepetsedwa kwambiri, Moyo wautumiki wa chinthucho ndi zaka ziwiri kapena kuposerapo. Kapangidwe ka thupi ndi mankhwala:
1. Kugwiritsa ntchito mafuta-benzene ndikwabwino kwambiri pa chothandizira, chifukwa thiophene ndi sulfure yonse mu benzene zimachepetsa ntchito ya chothandizira, chipangizocho chikayamba kugwira ntchito bwino, benzene yokazinga bwino kwambiri ingagwiritsidwe ntchito. 2. Pakutero, kutentha kwa malo otentha sikuyenera kupitirira 460℃. 3. Liwiro la malo la catalyst mkati mwa 2000-2500 h -1 limakhala ndi zotsatira zabwino kwambiri. Inde, ngati liwiro la malo ndi lalikulu kuposa apa, limagwiranso ntchito bwino, chifukwa ndi catalyst yokhala ndi liwiro lalikulu la malo. Phukusi ndi mayendedwe: Pa nthawi yosungira ndi kunyamula, chothandizirachi chimakhala cholimba kwambiri, chosalowa madzi ndipo sichiyenera kupitirira miyezi itatu chikayikidwa mumlengalenga. Tikhoza kulongedza mosavuta malinga ndi zosowa za makasitomala.
