FCC Igikoresho co Gutuma Y Zeolite: UMUNSI-30, UMUNSI-60 n'UMUSI-120

FCC Igikoresho co Gutuma Y Zeolite: UMUNSI-30, UMUNSI-60 n'UMUSI-120

DAY-30, DAY-60 na DAY-120 FCC ni zeolites Y (DAY) zidafise amabara, ari zo mu vy’ukuri ubwoko bw’amazeolite Y (USY) akomeye cane, kandi DAY series molecules sieves ni kimwe mu bihimba bihambaye bikora vy’ibikoresho vya FCC mu nganda zo gutunganya amavuta zo muri iki gihe.

Ni kuki FCC ikeneye igikoresho co gutera ivyatsi?

FCC ni ijambo ry’ikirundi risobanura Fluid Catalytic Cracking, igikorwa gihambaye co guhindura ibintu bitera amavuta mu bijanye n’ugutunganya amavuta. Intumbero ihambaye ya FCC ni uguhindura ibice bikomeye vya peteroli bikaba amavuta ya peteroli, LPG, propylène, olefines zidakomeye, dizeli, n’amavuta y’inzira yoroshe.

Ivyo bikoresho bifasha mu gutuma ibintu bigenda neza bikeneye gushitsa icarimwe ibisabwa vy’aside nyinshi, guhitamwo neza imiterere, ugushikama kw’ubushuhe bw’amazi, ubushobozi bwo guhangana n’uguhagarara neza, n’ubushobozi bwiza bwo guhindura amazi. Y-ubwoko bwa zeolite molecule sieves ni kimwe mu bihimba nyamukuru bikora vy’ibikoresho vya FCC vya none, kandi urutonde rwa DAY rw’ibikoresho vy’amamolekule ni ibiserukira Y-ubwoko bw’ibikoresho vy’amamolekule mu gisata ca FCC.

Igisesa c’amamolekule DAY ni iki?

DAY ihagarariye Dealuminated Y, kandi DAY molecule sieve mu bisanzwe yerekeza kuri Y-ubwoko bwa zeolite bwahinduwe mu gukuraho ivyuma. DAY molecular sieve si urutonde rwigenga rutandukanye rwose n’ubwoko bwa Y-zeolite, ahubwo ni ubwoko bw’ibintu vy’ubwoko bwa Y-bw’ivyuma vy’agaciro kanini vyakozwe n’ugukuraho ivyuma vy’ubwoko bwa Y-zeolite.

Biciye mu gukoresha ubushuhe bw’amazi n’imiti, Y-type molecule sieve irashobora gukuraho bimwe mu bice vy’aluminium, gutyo igahindura igipimo ca silica-to-alumina, aside, ugusangira kw’aside hagati, ugushikama kw’amazi, imiterere y’ibihengeri, ugushikama kw’ubushuhe, n’uguhitamwo kw’ibinyabuzima.

Kandi ibikoresho vya FCC bisaba ko amazi agira ubushuhe bwinshi. Ugereranije n’ibikoresho bisanzwe vy’ubwoko bwa Y-, ibikoresho vya DAY birashobora kwihanganira ubushuhe bwinshi-n’ibidukikije vy’ubushuhe bw’amazi vy’ibikoresho vy’ubuhinga bwa FCC.

Ibirango vy'imiterere y'ibikoresho vy'umusi

DAY ni iyo mu bwoko bwa Y-, kandi inzego zayo zifise ubuhinga bwa FAU busanzwe. Igishushanyo caco c’ibipimo bitatu-bifatanye n’ibindi bice bitatu bishobora gutuma ibintu bikorana n’ibintu bishobora gukwiragira mu gitereko.

Dealumination ni bumwe mu buryo buhambaye cane bwo guhindura imiterere y’ivyuma vy’umunsi, ariko si ikibazo co kugabanya gusa ibirimwo aluminium. Ku bikoresho vya FCC, birakenewe ko haba uburinganire hagati y’aside, imiterere y’ibihengeri, ugushikama kw’ubushuhe bw’amazi, n’uguhitamwo ibikoresho bitera.

Ni kuki DAY Zeolite ari ngirakamaro ku bikoresho vya FCC?

Nk’uko vyavuzwe, ibikoresho vya FCC bisaba gusubira gusubirana mu bushuhe bwinshi no mu bihe vy’umwotsi w’amazi, Dealuminated Y (DAY) zeolite yerekana ugushikama neza kw’ubushuhe bw’amazi kuruta ibikoresho bisanzwe vy’ubwoko bwa Y-. Ivyo bibanza vy’aside biri mu rwego rwa DAY birashobora gutuma habaho uguhindura ivyuma bikomeye vy’amazi bikagira ibintu vyoroshe, kandi ubuhinga bwavyo bushobora guhindurwa bugafatanywa n’ibikoresho vy’amazi kugira ngo bihindure ubushobozi bwo gukwiragira bw’ivyo bikoresho.

Ivyo bikoresho vya FCC ntibigamije gusa gucapura bikomeye cane, ahubwo bisaba kugenzura igikorwa co gucapura n’uguhitamwo ibintu. DAY zeolite ishobora kugenzurwa biciye ku bipimo nk’igipimo ca silica-ku -alumina, ubunini bw’intete, aside, n’imiterere y’ibihengeri.

Ivyiza ni uko FCC catalyst mu vy’ukuri atari umusenyi w’amamolekule! Ni urutonde rw’ibintu vyinshi rugizwe n’ibihimba vy’umubiri bikorana n’ibindi bihimba, ibihimba vy’umubiri, ibihimba vy’umubiri bifatanya n’ibindi bihimba bikora. DAY molecular sieve ni kimwe mu bikoresho nyamukuru bikora vy’umuyagankuba wa FCC, birabereye gufatanya n’umuyagankuba w’umuyagankuba, aho kuba umuyagankuba wuzuye wa FCC ubwawo.

DitandukaniroBhagati y'UMUNSI-30, UMUNSI-60And UMUNSI-120

UMUNSI-30 Igitera: Ifise urugero rutoyi rwo gukuraho aluminium, ishimika ku gikorwa c’aside n’ugusaduka, kandi ikurikirana igipimo kinini co guhindura, ariko ifise impengamiro nini cane yo gutanga coke.

UMUNSI-60 Igitera: Ifise urugero ruringaniye rwo gukuraho ivyuma n’uburinganire bwiza hagati y’ibikorwa vy’aside n’ugushikama, bikaba biyigira ubwoko busanzwe bw’ibikoresho vy’inganda FCC.

UMUNSI-120 Igitera: Ifise urugero rwimbitse rwo gukuraho ivyuma kandi ni igice c’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma. Ikoreshwa ku bikoresho vy'ubuhinga bwa FCC bikora cane.

Kugira ngo ushobore guhitamwo ubwoko bwiza bw’ibikoresho vy’uruhererekane vya DAY, reka tugereranye mu buryo burambuye:
