FCC Catalyst Dealuminated Y Zeolite: TILE-30, TILE-60 ani TILE-120

DAY-30, DAY-60 ani DAY-120 FCC katalisita ye Y (DAY) zewoli dealuminé ye, minnu ye Y zewoli suguya ye min sabatilen don kosɛbɛ (USY), ani DAY seriyali molekiyɔmu sizow ye FCC katalisitaw ka baarakɛminɛn nafama dɔ ye bi tulu saniya baarakɛyɔrɔw la.

Mun na FCC mago bɛ Catalyst de Sieve Moleculaire la?

FCC kɔrɔ ye Fluid Catalytic Cracking ye, o ye katalizi jiginni fɛɛrɛ nafama ye tulu saniya baara la. FCC ka laɲini fɔlɔ ye ka petoroli tilayɔrɔba girinmanw sɛmɛntiya ka kɛ gazi ye, GPL, poropilini, olefini nɔgɔmanw, dizili, ani tulu nɔgɔlen.

FCC katalisitaw ka kan ka asidi caman, u cogoya sugandili ɲuman, jisuma sabatili, u ka se ka u yɛrɛ tanga baarakɛcogo ɲuman ma, ani ka jibɔ kɛcogo ɲuman wajibiyalenw dafa waati kelen na. Y-suguya zewoli molekiyɔmu sizow ye bi FCC katalisitaw ka baarakɛminɛn koloma dɔ ye, wa DAY seriyali molekiyɔmu sizow ye Y-suguya molekiyɔmu sizo fɛnw jiralenw ye FCC foro kɔnɔ.

DAY Molecular Sieve ye mun ye?

DAY kɔrɔ ye Dealuminated Y ye, wa DAY molecular sieve bɛ tali kɛ Y-suguya zewoli la min ye dealuminated modification kɛ. DAY molekiyɔmu sizo tɛ karamɔgɔya yɛrɛmahɔrɔnyalen ye min ni Y-suguya zewoli tɛ kelen ye pewu, nka a ye fɛn suguya ye min ka bon-silika Y-suguya fɛn min dilannen don ni Y-sugu zewoli dealuminasi ye.

Jisuma ni kemikali furakɛli fɛ, Y-suguya molekiyɔmu sizo bɛ se ka aliminiyɔmu karamɔgɔya dɔw bɔ ni sugandi ye, o la, a bɛ silika-ni-alumini hakɛ, asidi, asidi cɛmancɛ tilali, jisuma sabatili, porow jɔcogo, funteni sabatili, ani katalitiki sugandili caman sɛmɛntiya.

Ani FCC katalisitaw bɛ jisuma sabatili caman de wajibiya. Ni an y’a suma ni Y-suguya mɔlikɛlan gansanw ye, DAY molekiyɔmu sizow bɛ se ka FCC katalisitaw ka funteni ni jisuma sigidaw muɲu ka ɲɛ.

DAY Molecular Sieves ka sigicogo

DAY ye Y-suguya molekiyɔmu sizo sitɛmu ta ye, wa a karamɔgɔya bɛ ni FAU topidiya danma ye. A ka fɛn saba-mikɔrɔporozi jɔcogo min bɛ ɲɔgɔn na, o b’a to fɛnɲɛnamafagalanw ni fɛnw bɛ se ka jɛnsɛn kristalɛ kɔnɔ.

Dealumination ye structurel modification fɛɛrɛ nafama dɔ ye DAY molecular sieve la, nka a tɛ aliminiyɔmu hakɛ dɔgɔyali dɔrɔn ye. FCC katalisitaw ta fan fɛ, balansi ka kan ka kɛ asidi, porozɛw jɔcogo, jisuma sabatili, ani katalisita sugandili cɛ.

Mun na DAY Zeolite nafa ka bon FCC katalisiw bolo?

I n’a fɔ a fɔra cogo min na, FCC katalisitaw bɛ segin-ka-bɔnyew wajibiya funteni ni jisuma cogoyaw la, Dealuminated Y (DAY) zeolite bɛ jisuma sabatili ɲuman jira ka tɛmɛ Y-suguya molekiyɔmu sieve gansanw kan. Asidi santiri minnu bɛ DAY hukumu kɔnɔ, olu bɛ se ka hidrɔkarbon girinmanw jiginni sabati kosɛbɛ ka kɛ fɛn nɔgɔmanw ye, wa a ka mikroporozɛni cogoya saba-yɔrɔ bɛ se ka sɛmɛntiya ani ka fara ɲɔgɔn kan ni matiriyali fɛnw ye walasa ka katalisita ka jɛnsɛnni baarakɛcogo ladilan.

FCC katalisita tɛ dɔrɔn ka kari barikama kɛ, nka u bɛ kari baara ni fɛn dilannenw sugandili kɔlɔsili de wajibiya. DAY zewoli bɛ se ka kɔlɔsi ni fɛnw ye i n’a fɔ silika-ni-alumina hakɛ, suman hakɛ, asidi, ani porow jɔcogo.

Kɛrɛnkɛrɛnnenya la, FCC katalisita tɛ tiɲɛ na sizo molekilɛri saniyalen ye! O ye sigida ye min bɛ Kɛ ni molekiyɔmu sizo, matirili, sirilan ani baarakɛminɛn wɛrɛw ye. DAY molecular sieve ye FCC katalisita ka baarakɛminɛn koloma dɔ ye, a bɛnnen don ka fara ɲɔgɔn kan ni katalisita matirili ye, sanni a ka kɛ FCC katalisita dafalen yɛrɛ ye.

Differences (fɔcogo wɛrɛw).Between TILE-30, TILE-60And TILEN-120

TILE-30 Katalisita: A ka dealuminizasiyɔn hakɛ ka dɔgɔn, a bɛ sinsin asidi ni kari baara kan, wa a bɛ tugu fɛn caman tigɛli hakɛ kɔ, nka a ka teli ka coke bɔ.

TILE-60 Katalisita: A bɛ dealuminasiyɔn hakɛ danmadɔ sɔrɔ ani balansi ɲuman bɛ asidi baara ni sabatili cɛ, o b’a to a bɛ kɛ izini FCC katalisita suguya ye min bɛ kɛ tuma bɛɛ.

TILE-120 Katalisita: A ka dealuminasiyɔn hakɛ ka dun ani a ye silisi caman-silisi ye, Y molekiyɔmu sieve min sabatilen don kosɛbɛ, ni jisuma sabatili ɲuman bɛ a la, a ka coke sɔrɔli ŋaniya ka dɔgɔn, ani a katalisita si ka jan. A bɛ tali kɛ FCC katalitiki sitɛmuw la minnu bɛ baara kɛ kosɛbɛ.
