Kuki FCC ikeneye Catalizeri ya molekile?

FCC isobanura Fluid Catalytic Cracking, inzira ikomeye yo guhindura catalitike mu nganda zitunganya peteroli. Intego nyamukuru ya FCC nuguhindura ibice bya peteroli biremereye muri lisansi, LPG, propylene, olefine yoroheje, mazutu, namavuta yumucyo.

Cataliseri ya FCC igomba guhura icyarimwe ibisabwa bya acide nyinshi, guhitamo imiterere myiza, hydrothermal stabilite, kurwanya neza gukuraho, hamwe no gukora neza. Y - ubwoko bwa zeolite ya molekile ya sikeli nimwe mubintu byingenzi bigize catalizike ya kijyambere ya FCC, kandi DAY urukurikirane rwimashini ya molekile ihagarariye Y - ubwoko bwa molekile ya sikeli mu murima wa FCC.

UMUNSI W'UMUNSI W'UMUNSI?

UMUNSI bisobanura Dealuminated Y, na DAY ya molekile ya DAY mubisanzwe yerekeza kuri Y - ubwoko bwa zeolite bwahinduwe. UMUNSI wa molekile ya elegitoronike ntabwo ari urwego rwigenga rutandukanye rwose na Y - ubwoko bwa zeolite, ahubwo ni ubwoko bwibikoresho byo hejuru - silika Y - ibikoresho byatewe no gusenya ubwoko bwa Z -.

Binyuze mu kuvura hydrothermal na chimique, Y - ubwoko bwa molekile ya elegitoronike irashobora guhitamo guhitamo bimwe mubikorwa bya aluminiyumu, bityo igahindura silika - ikagera kuri - igipimo cya alumina, acide, ikwirakwizwa rya acide, ihindagurika rya hydrothermal, imiterere ya pore, ituze ryumuriro, hamwe no guhitamo catalitiki.

Kandi catisale ya FCC isaba hydrothermal stabilite. Ugereranije na Y - ubwoko bwa molekile isanzwe, amashanyarazi ya DAY ya molekile irashobora guhangana nubushyuhe bwo hejuru - nubushyuhe bwa hydrothermal ibidukikije bya catalizike ya FCC.

Ibiranga Imiterere yumunsi Molecular Sieves

UMUNSI ni uw'ubwoko bwa Y -, kandi urwego rwayo rufite topologiya ya FAU. Ibice bitatu - bigizwe na microporome imiterere ituma reaction n'ibicuruzwa bikwirakwira muri kristu.

Dealumination nimwe muburyo bwingenzi bwo guhindura imiterere ya DAY molekulari ya DAY, ariko ntabwo arikibazo cyo kugabanya ibirimo aluminium. Kuri catalizike ya FCC, hagomba kubaho kuringaniza aside, imiterere ya pore, hydrothermal stabilite, hamwe no guhitamo catalitiki.

Kuki UMUNSI Zeolite ari ingenzi kubatangizi ba FCC?

Nkuko byavuzwe, catalizike ya FCC isaba guhindurwa inshuro nyinshi mugihe cy'ubushyuhe bwinshi nubushyuhe bwamazi, Zeolite ya Dealuminated Y (DAY) yerekana hydrothermal ihagaze neza kuruta amashanyarazi ya Y -. Centre acide murwego rwa DAY irashobora guteza imbere ihinduka rya hydrocarbone iremereye kubicuruzwa byoroheje, kandi imiterere ya mikorobe itatu - irashobora guhinduka kandi igahuzwa nibikoresho bya matrix kugirango ihindure imikorere ya catalizator.

Cataliseri ya FCC ntabwo igamije gusa gucika intege, ahubwo isaba kugenzura ibikorwa byo gucamo no guhitamo ibicuruzwa. UMUNSI zeolite urashobora kugenzurwa hifashishijwe ibipimo nka silika - kugeza - igipimo cya alumina, ingano yingano, acide, nuburyo bwa pore.

Ikigaragara ni uko catisale ya FCC mubyukuri ntabwo ari molekile nziza! Nuburyo bwa sisitemu igizwe na molekile ya elegitoronike, matrix, binder, nibindi bikoresho bikora. UMUNSI wa molekile ya elegitoronike nimwe mubikoresho byingenzi bya catalizike ya FCC, birakwiriye guhuzwa na materix ya catalizator, aho kuba catisale yuzuye ya FCC ubwayo.

DifferencesBhagati yumunsi-30, UMUNSI-60And UMUNSI-120

UMUNSI-30 Catalizator: Ifite urwego ruto rwo gucuruza, ishimangira acide nigikorwa cyo guturika, kandi ikurikirana umuvuduko mwinshi, ariko ifite imyumvire myinshi yo kubyara kokiya.

UMUNSI-60 Catalizator: Ifite urwego ruciriritse rwo gusezerana hamwe nuburinganire bwiza hagati yibikorwa bya aside no gutuza, bigatuma iba ubwoko rusange bwinganda za FCC.

UMUNSI-120 Catalizator: Ifite urwego rwimbitse rwo gusezerana kandi ni silika ndende - silika, ultra - icyuma cya molekuline Y ihamye hamwe na hydrothermal stabilite nziza, kugabanuka kwa kokiya yo hasi, hamwe nubuzima bwa catalizator igihe kirekire. Irakoreshwa murwego rwo hejuru - imikorere ya sisitemu ya catalitiki ya FCC.

Kugufasha guhitamo ubwoko bukwiye bwa DAY ikurikirana ya molekile ya sikeri, reka dukore igereranya rirambuye:
