FCC Catalyst Dealuminated Y Zeolite: OLUNAKU-30, OLUNAKU-60 ne OLUNAKU-120

FCC Catalyst Dealuminated Y Zeolite: OLUNAKU-30, OLUNAKU-60 ne OLUNAKU-120

DAY-30, DAY-60 ne DAY-120 FCC catalysts zibeera dealuminated Y (DAY) zeolites, nga mu bukulu kika kya ultra-stable Y zeolite (USY), era DAY series molecular sieves kye kimu ku bitundu ebikulu ebikola mu FCC catalysts mu makolero ag’omulembe agalongoosa amafuta.

Lwaki FCC Yeetaaga Molecular Sieve Catalyst?

FCC kitegeeza Fluid Catalytic Cracking, enkola enkulu ey’okukyusa catalytic mu mulimu gw’okulongoosa amafuta. Ekigendererwa ekikulu ekya FCC kwe kukyusa obutundutundu bw’amafuta amazito okufuuka petulooli, LPG, propylene, light olefins, dizero, ne light cycle oil.

FCC catalysts zeetaaga okutuukiriza mu kiseera kye kimu ebyetaago bya asidi omungi, okulonda enkula ennungi, okunyweza amazzi amangi, okuziyiza obulungi okuziyiza, n’okukola obulungi amazzi. Y-type zeolite molecular sieves kye kimu ku bitundu ebikulu ebikola mu FCC catalysts ez’omulembe, era DAY series of molecular sieves zikiikirira Y-type molecular sieve products mu nnimiro ya FCC.

DAY Molecular Sieve Kiki?

DAY kitegeeza Dealuminated Y, era DAY molecular sieve etera okutegeeza zeolite ey’ekika kya Y-ebadde ekyusibwamu dealuminated. DAY molekyu sieve si nkola eyetongodde eyawukana ddala ku zeolite ey’ekika kya Y-, wabula ekika ky’ekintu eky’ekika kya Y-silica ekinene-ekikolebwa nga kikolebwa dealumination ya zeolite ey’ekika kya Y-.

Okuyita mu kujjanjaba amazzi n’eddagala, ssefuliya ya molekyu ey’ekika kya Y- esobola okulonda okuggyawo ebimu ku aluminiyamu ow’omusingi, bwe kityo ne kikyusa omugerageranyo gwa silika-ku-alumina, asidi, okusaasaana kw’amasekkati ga asidi, okutebenkera kw’amazzi, ensengekera y’obutuli, okutebenkera kw’ebbugumu, n’okulonda okutabula.

Era FCC catalysts zeetaaga okutebenkera kw’amazzi ag’ebbugumu okusingawo. Bw’ogeraageranya n’ebisengejja molekyu eby’ekika kya Y- ebya bulijjo, ebisengejja molekyu ebya DAY bisobola bulungi okugumira embeera z’ebbugumu eringi- n’obugumu bw’amazzi obw’ebirungo ebiziyiza FCC.

Engeri Y'enzimba Y'Ebisengejja Molekyule Y'OLUNAKU

DAY eri mu nkola ya molekyu ey’ekika kya Y-, era ensengekera yaayo erina topology ya FAU eya bulijjo. Ensengekera yaayo eya microporous ekwatagana mu bitundu bisatu-esobozesa ebisengejja n’ebivaamu okusaasaana munda mu kirisitaalo.

Dealumination y’emu ku nkola ezisinga obukulu ez’okukyusa enzimba ya DAY molecular sieve, naye si nsonga ya kukendeeza ku bungi bwa aluminiyamu yokka. Ku FCC catalysts, balance yeetaaga okukubwa wakati wa acidity, pore structure, hydrothermal stability, ne catalytic selectivity.

Lwaki DAY Zeolite Mukulu Eri FCC Catalysts?

Nga bwe kyayogeddwa, ebiziyiza bya FCC byetaaga okuddamu okukola enfunda eziwera wansi w’embeera y’ebbugumu eringi n’omukka gw’amazzi, Dealuminated Y (DAY) zeolite eraga okutebenkera okulungi mu bbugumu ly’amazzi okusinga ebisengejja molekyu ebya bulijjo ebya Y-type. Ebifo bya asidi mu nkola ya DAY bisobola bulungi okutumbula okukyusa haidrokaboni enzito okudda mu bikozesebwa ebizito, era ensengekera yaayo eya microporous ey’ebitundu bisatu- esobola okukyusibwa n’egattibwa n’ebintu bya matrix okutereeza omulimu gw’okusaasaana kw’ekirungo ekiziyiza.

FCC catalysts tezigenderera kwokka kwatika kwa maanyi, wabula zeetaaga okufuga emirimu gy’okukutula n’okulonda ebintu. DAY zeolite esobola okufugibwa okuyita mu bipimo nga omugerageranyo gwa silika-ku-alumina, obunene bw’empeke, asidi, n’ensengekera y’obutuli.

Ekikulu, FCC catalyst mu butuufu si pure molecular sieve! Ye nkola ya molekyo ekoleddwamu molekyu ssefuliya, matrix, binder, n’ebitundu ebirala ebikola. DAY molecular sieve kye kimu ku bintu ebikulu ebikola ebya FCC catalyst, kirungi okugatta ne catalyst matrix, okusinga okuba nga FCC catalyst enzijuvu yennyini.

Debitali bimu (ifferences).Bwakati w’OLUNAKU-30, OLUNAKU-60And OLUNAKU-120

OLUNAKU-30 Catalyst: Kirina diguli eya wansi ey’okuggya aaluminizaamu, essira lissa essira ku asidi n’emirimu gy’okukutuka, era kigoberera omutindo gw’okukyusa ogw’amaanyi, naye kirina omuze gwa waggulu nnyo ogw’okukola coke.

OLUNAKU-60 Catalyst: Eriko diguli ey’ekigero ey’okukendeeza ku alumination ate nga erina bbalansi ennungi wakati w’emirimu gya asidi n’okutebenkera, ekigifuula ekika kya bulijjo eky’ebirungo ebikola FCC mu makolero.

OLUNAKU-120 Catalyst: Kirina diguli enzito ey’okuggya alumination era nga silika ya waggulu-silika, ultra-stable Y molecular sieve nga erina okutebenkera okusinga obulungi mu hydrothermal, enkola ya coke eya wansi, n’obulamu bwa catalyst obuwanvu. Kikozesebwa ku nkola za FCC ezikola emirimu egy’amaanyi-.

Okusobola okukuyamba okulonda ekika ekituufu ekya DAY series molecular sieves, ka tukole okugeraageranya okusingawo:
