Nā hiʻohiʻona o nā mea hoʻokalakupua
Loaʻa i nā catalysts particulate kahi ākea kikoʻī kiʻekiʻe a me ka porosity, e hoʻomaikaʻi nui ana i ka hopena. Hoʻolālā ʻia kā mākou methanol-to-aromatics catalysts a me hydrogenation catalysts ma ke ʻano ʻāpana, e hōʻike ana i ke kūpaʻa maikaʻi loa a me ke koho. Ma waena o lākou, loaʻa i nā huahana sieve zeolite molecular sieve nā topologies kūikawā e like me FAU/MWW.
ʻO nā mea hoʻoheheʻe maʻemaʻe kahi papa nui o nā mea i hoʻohana nui ʻia i nā kahua kemika, kaiapuni, a me ka ikehu. ʻO kā lākou morphology particle kūikawā a me ka hana catalytic e lilo lākou i mea koʻikoʻi i nā kaʻina hana ʻenehana. Ka noi o particulate catalysts ua nui ma luna o ko lakou kiʻekiʻe kiko'ī ili wahi, maikaʻi dispersibility, a me ka catalytic hana, ka mea hiki ke ho'ēmi i ka ikehu ho'āla a me ka hoʻoikaika 'ana i ka helu a me ka selectivity i kemika reactions.
ʻO ka hana catalytic o nā mea hoʻoheheʻe maʻemaʻe mai ko lākou mau wahi hoʻoikaika kino. Hiki i kēia mau pūnaewele ke hoʻopili i nā molekole reactant, e hāpai ana i ka haki ʻana a me ka hoʻokumu ʻana i nā mea paʻa kemika. ʻAʻole hoʻonui wale ka hoʻolālā particulate i ka wahi pili ma waena o ka catalyst a me nā reactants akā hoʻomaʻamaʻa hoʻi i ka kahe a me ka hoʻopuehu ʻana i loko o ka reactor, e hoʻomaikaʻi ana i ka pono o ka hoʻoili nui ʻana. Eia kekahi, loaʻa i nā catalysts particulate ka ikaika mechanical kiʻekiʻe, e kūʻē i ka ʻaʻahu kino a me ka corrosion kemika i ka wā o ke kaʻina hana, e hoʻolōʻihi i ko lākou ola lawelawe.
