amashanyarazi ya molekile, zeolite ZSM-23

Zeolite ni itsinda ryamabuye y'agaciro asanzwe akoreshwa cyane mubikorwa bitandukanye byinganda kubera imiterere yihariye. Mu bwoko butandukanye bwa zeolite, ZSM-23 igaragara nkicyuma cyiza cya molekile ikora neza hamwe nuburyo bwinshi bukoreshwa mubikorwa bya peteroli na chimique. Muri iyi ngingo, tuzasesengura ibiranga, synthesis, hamwe nibisabwa bya ZSM-23, tumenye akamaro kayo mubijyanye na catalizike na adsorption.

Zeolite ni imyunyu ngugu ya kristaline ya aluminiyose ifite imiterere nini n'ubuso burebure. Iyi mitungo ibagira abakandida beza kubisabwa nka adsorption, ion guhana, hamwe na catalizike. ZSM-23, byumwihariko, ni ubwoko bwa zeolite izwiho imiterere yihariye ya pore no guhitamo cyane kuri molekile zimwe. Ibikoresho byayo bya molekile bigira ibikoresho byingenzi byo gutandukanya no kweza ibice bitandukanye mubikorwa byinganda.

Synthesis ya ZSM-23 ikubiyemo gukoresha preursors yihariye nuburyo bwo kwitwara kugirango igenzure imiterere yimiterere yayo. Mubisanzwe, ZSM-23 ikomatanyirizwa hamwe ikoresheje hydrothermal process, aho imvange ya alumina, silika, hamwe nuyobora ibyubaka ikorerwa ubushyuhe bwinshi nigitutu. Ibikoresho bivamo kristu noneho bivurwa neza kugirango bikureho umwanda uwo ariwo wose kandi uhindure imitungo ya porogaramu yihariye.

Kimwe mu bintu by'ingenzi biranga ZSM-23 ni imiterere yacyo ya microporome, igizwe n'imiyoboro ihuza imiyoboro hamwe n'akazu k'ibipimo nyabyo. Iyi miterere idasanzwe ituma ZSM-23 ihitamo molekules ya adsorb ukurikije ubunini bwayo n'imiterere, bigatuma iba ibikoresho byiza muburyo bwo gutandukana. Byongeye kandi, imiterere ya acide yubuso bwa ZSM-23′s ituma ishobora guhagarika imiti itandukanye yimiti, ikomeza kwagura akamaro kayo mubikorwa byinganda.

Mu nganda zikomoka kuri peteroli, ZSM-23 ikoreshwa cyane nkumusemburo wo guhindura hydrocarbone mubicuruzwa byagaciro nka lisansi nabahuza peteroli. Guhitamo kwinshi kuri molekile zimwe na zimwe za hydrocarubone bituma iba ikintu cyingenzi mubikorwa nka catalitike yameneka na hydrocracking, aho guhindura neza ibiryo mubicuruzwa byifuzwa ningirakamaro mubikorwa rusange byimikorere.

Byongeye kandi, ZSM-23 igira uruhare runini mu gukora imiti myiza n’imiti ihuza imiti. Ubushobozi bwayo bwo guhitamo adsorb no guhagarika molekile zihariye bituma iba igikoresho ntagereranywa cyo guhuza ibinyabuzima bigoye hamwe nubuziranenge bwinshi numusaruro. Byongeye kandi, ZSM-23 ikoreshwa mugusukura imyuka n’amazi, aho imitunganyirize ya molekile yayo ituma hakurwaho umwanda n’umwanda mu migezi itandukanye.

Ubwinshi bwa ZSM-23 bugera no mubidukikije. Ikoreshwa ryayo nk'umusemburo wo gutunganya imyuka ihumanya no kuvana umwanda mu myanda iva mu nganda byerekana akamaro kayo mu gukemura ibibazo by’ibidukikije. Mu koroshya guhindura imyuka yangiza mu bintu bitangiza, ZSM-23 igira uruhare mu kugabanya ihumana ry’ikirere no kurengera ibidukikije.

Mu rwego rw’ingufu zishobora kuvugururwa, ZSM-23 yerekanye amasezerano mu gukora ibicanwa binyuze muri catalitike ihindura ibiryo bikomoka kuri biomass. Ubushobozi bwayo bwo guhitamo ibice bigize biomass mu bicanwa bifite agaciro n’imiti bihuza n’inyungu zigenda ziyongera ku masoko y’ingufu zirambye kandi zangiza ibidukikije.

Imiterere yihariye ya ZSM-23 nayo yakuruye ibitekerezo mubijyanye na nanotehnologiya, aho ubushakashatsi bwakoreshejwe nk'icyitegererezo cyo guhuza ibikoresho bya nanostructures. Mu gukoresha neza imiterere ya pore ya ZSM-23, abashakashatsi bashoboye gukora nanomateriali nshya ifite imiterere ijyanye no gukoresha ibikoresho bya elegitoroniki, catalizike, no kubika ingufu.

Mu gusoza, ZSM-23 igaragara nkicyuma cya molekile ikora neza kandi ikoreshwa muburyo butandukanye mu nganda za peteroli, imiti, n’ibidukikije. Imiterere yihariye ya pore, ubushobozi bwa adsorption ubushobozi, hamwe na catalitiki ituma iba ibikoresho byingirakamaro mubikorwa bitandukanye byinganda. Mu gihe ubushakashatsi n’iterambere mu rwego rwa zeolite bikomeje gutera imbere, amahirwe yo kurushaho guhanga udushya no gushyira mu bikorwa ZSM-23 aratanga ikizere, bigatanga inzira yo gukomeza kugira akamaro mu gukemura ibibazo bikenerwa n’inganda zigezweho.
