Henan Sinmat Chemical Co., Ltd. waa mid ka mid ah soosaarayaasha ugu kalsoonaan karo iyo alaab-qeybiyeyaasha zeolite catalyst mcm-41 ee Shiinaha. Iyada oo leh waayo-aragnimo badan, waxaanu si diiran kuugu soo dhawaynaynaa inaad iibsato tayo sare oo zeolite catalyst mcm-41 oo iib ah halkan warshadeena. Nala soo xidhiidh muunad bilaash ah.
Hordhac
MCM-41 zeolite catalyst waa maaddo silica mesoporous ah oo la dalbado, oo badiyaa leh silica sida shayga qaab dhismeedka ugu weyn, iyo cabbirrada daloolka guud ahaan u dhexeeya 2 ilaa 50 nm. Sida shaandho molecular mesoporous, MCM-41 waxay u adeegi kartaa sidii adsorbent, side kicinta, walxaha kicinta, walxaha kala soocida, iyo taageerada walxaha kale ee shaqaynaysa.
MCM-41 shaandho molecular waxaa lagu gartaa kanaal mesoporous oo laba geesood ah oo si joogto ah loo habeeyay, oo leh lebis iyo cabbir dalool la hagaajin karo. Waxayna soo bandhigaysaa meel sare oo gaar ah, mugga daloolka weyn, sifooyinka fidinta molecular ee aad u wanaagsan, fududaynta shaqaynta dusha sare, iyo awoodda wax-qaadashada wanaagsan. Tani waa mid ka mid ah faa'iidooyinkeeda ugu weyn ee catalysis, halkii ay ka ahaan lahayd aysidhka xooggan ee dabiiciga ah.
MCM-41 waa taageero firfircoon oo muhiim ah, waxay wanaajin kartaa kala firdhinta qaybaha firfircoon waxayna kor u qaadi kartaa faafinta falcelinta iyo alaabada iyada oo loo marayo qaab dhismeedka mesoporous. MCM-41 waxa kale oo uu si gaar ah ugu habboon yahay kasbashada batroolka ee ku lug leh molecules waaweyn, iyo sidoo kale farsamaynta makromolecules-ka oo ay adag tahay in lagu maareeyo zeolites-ka caadiga ah. Intaa waxaa dheer, MCM-41 shaandho molecular waxaa loo isticmaali karaa xayeysiisyada wasakhaha organic, inorganic iyo gaseous, taas oo ay ugu wacan tahay bedkeeda gudaha ee aadka u weyn.
