ʻO ZSM molecular sieve kahi ʻano silicaluminate crystalline me ka nui o ka pore a me ke ʻano, i hoʻohana nui ʻia i nā hopena kemika ma muli o kāna hana catalytic maikaʻi loa.
Ma waena o lākou, ʻo ka hoʻohana ʻana o ZSM molecular sieve i ke kula o ka isomerization catalyst ua hoʻokipa nui ʻia.
Ma ke ʻano he catalyst isomerization, loaʻa iā ZSM molecular sieve nā mea maikaʻi aʻe:
1. Acidity a me ka paʻa: ZSM molecular sieve he kiʻekiʻe ka acidity a me ka paʻa, hiki ke hāʻawi i nā kūlana kūpono kūpono a hoʻoikaika i ka hoʻoulu ʻana a me ka hoʻololi ʻana o nā substrates.
2. Ka nui o ka pore a me ke ʻano: ZSM molecular sieve he ʻokoʻa ka nui a me ke ʻano o ka pore, hiki ke nānā a hoʻopaʻa i ka diffusion a me ka hoʻopili ʻana o nā reactants a me nā huahana, a laila e hoʻomaikaʻi ai i ka hana a me ke koho ʻana o ka catalyst.
3. Ka hana hoʻololi: Ma ka hoʻoponopono ʻana i nā kūlana synthesis a me nā ʻano hana hope o ka ZSM molecular sieve, hiki ke hoʻomalu ʻia ka nui o kona pore, ke ʻano, ka acidity a me ke kūpaʻa no ka hoʻololi ʻana i nā pono o ka isomerization reaction.
I ka hopena isomerization, ZSM molecular sieve i hoʻohana nui ʻia e like me ka isomerization catalyst, hiki ke hoʻoikaika i ka hoʻololi like ʻana o nā substrates a ʻike i ka synthesis maikaʻi o nā huahana.
No ka laʻana, ma ke kahua o ka petrochemical, ZSM molecular sieve ua hoʻohana nui ʻia i ka isomerization hydrocarbon, alkylation, acylation a me nā hopena ʻē aʻe e hoʻomaikaʻi ai i ka maikaʻi a me ka hua o nā huahana petroleum.
I ka pōkole, ʻo ZSM molecular sieve, ma ke ʻano he catalyst isomerization maikaʻi loa, he ʻano nui o nā noi i ka petrochemical, organic synthesis, mālama kaiapuni a me nā māla ʻē aʻe.
Me ka noiʻi hou a me ka hoʻomaikaʻi hou ʻana, hiki ke manaʻo ʻia e pāʻani i kahi hana koʻikoʻi i ka wā e hiki mai ana.
