I. Kupu Whakataki
ZSM-5 molecular sieve ko te ahua o te rauemi microporous ki te hanganga ahurei, kua whakamahia whānuitia i roto i te maha mara no te mea o ona āhuatanga adsorption pai, pūmautanga me te mahi catalytic. I roto i tenei pepa, ko te tono me te whakahiato o te ZSM-5 molecular sieve ka whakaatuhia i roto i nga korero.
Tuarua, tono o ZSM-5 tatari rāpoi
1. Catalyst: Na te nui o te waikawa me te hanganga pore ahurei o ZSM-5 molecular sieve, kua waiho hei whakakorikori pai mo te maha o nga tauhohenga matū, penei i te isomerization, alkylation, dehydration, etc.
2. Adsorbent: ZSM-5 molecular sieve he nui te rahi o te pore me te pai o te mahi adsorption, a ka whakamahia nuitia i roto i te wehenga hau, te wehenga wai me te kawe whakakorikori me etahi atu mara.
3. Kaikawe kaikawe: ka taea te whakamahi hei kaikawe hei whakapai ake i te mahi me te pumau o te kaikawe.
Te whakahiato o te tatari ngota ZSM-5
Ko te whakahiato o te ZSM-5 molecular sieve te nuinga o te whakamahi i te tikanga tauira, e whakahaere ana i te tukanga whakahiato ma te whakahaere i te pāmahana, te pehanga, te ōwehenga rauemi mata me etahi atu tikanga. I roto ia ratou, ko nga rauemi mata e whakamahia nuitia ana ko te konutai silicate me te konutai aluminate.
1. Te whakahaere i te ōwehenga silica-konumohe: ko te ōwehenga silica-konumohe ko tetahi o nga waahanga nui o te ZSM-5 molecular sieve, ka taea te whakahaere ma te whakatika i te ōwehenga o te konutai konutai me te konutai konutai. Ko te teitei ake o te owehenga o te silicon ki te konumohe, ka kaha ake te anga o te tatari ngota i hangaia ki te silicon, me te rereke.
2. Te pāmahana me te pehanga whakahiato: he mea nui ano te pāmahana me te pehanga whakahiato e pa ana ki te hanganga o te tatari ngota ZSM-5. I te nuinga o te waa, ko te teitei ake o nga pāmahana me nga pehanga e pai ana ki te hanga o nga tatari ngota ZSM-5.
3. Te wa whakatioata me te pāmahana whakatioatanga: ko te wa whakatioatanga me te pāmahana whakatioatanga he mea nui e pa ana ki te hanganga o te tatari mole ZSM-5. Ko te tere o te hanga me te ma o ZSM-5 molecular sieve i pai ake ma te whakanui ake i te pāmahana whakamaarama i te wa e tika ana te whakamaarama.
4. Nga awhina waihanga: I etahi wa ki te whakatika i te uara pH, ki te whakatairanga ranei i te tukanga tioata, he mea tika ki te whakauru i etahi awhina waihanga, penei i te NaOH, NH4OH, etc.
Iv. Whakamutunga
Hei taonga moroiti nui, ZSM-5 molecular sieve he whanui tono. He mea nui kia mohio ki te tikanga whakahiato mo tona whakamahinga whanui. Ma te whakahaere i nga tikanga whakahiatotanga, ka taea te whakahaere pai te hanganga pore, te waikawa me nga ahuatanga catalytic o ZSM-5 molecular sieve, e whakarato ana i etahi atu huarahi mo tana tono i roto i nga momo mara.
