mmanụ aṅụ zeolite molekụla sieve

nkọwa ngwaahịa:

Isi ihe nke mmanụ aṅụ zeolite bụ eke zeolite, nke bụ ihe inorganic microporous ihe mejupụtara SiO2, Al2O3 na alkaline metal ma ọ bụ alkaline ụwa metal. Olu pore dị n'ime ya bụ 40-50% nke mkpokọta olu na mpaghara elu ya kpọmkwem bụ 300-1000 m2 / g. Ọ nwere njirimara nke nguzogide okpomọkụ dị elu, enweghị ọkụ ọkụ, nkwụsi ike dị mma na nkwụsi ike nke hydrothermal. Ọ bụ ihe na-ebu ọrụ siri ike nke molikula na-arụ ọrụ nke ọma, enweghị mmetọ nke abụọ, enwere ike ịmaliteghachi na okpomọkụ dị elu. E jiri ya tụnyere carbon a na-arụ ọrụ mmanụ a honeyụ, arụmọrụ ya dị ihe dịka 25%. Ịrụ ọrụ dị elu, nke a na-ejikarị eme ihe na adsorption, nkewa, catalysis na ubi gburugburu ebe obibi, dị mma maka nnukwu ikuku ikuku, obere ịta ahụhụ organic n'efu gas ọgwụgwọ.

Atụmatụ:

1. Nhọrọ adsorption siri ike: sieve molecular nwere nha pore dị mma na nke edo ma bụrụkwa ihe mgbasa ozi ionic. Ya mere, ọ nwere ike họrọ adsorb dị ka nha na polarity nke ụmụ irighiri ihe, ma nwee ike wepụ ethylene na propylene nke ọma na hydrocarbons jupụtara. A na-ekpebi iwepụ acetylene site na ethylene site na polarity siri ike.

2. Ike mgbasa ozi siri ike: Ọbụlagodi na ntinye ihe mejupụtara gas dị ntakịrị, ọ ka nwere ikike mgbasa ozi.

3. Ọ na-emetụta obere okpomọkụ ma ka nwere ikike mgbasa ozi ka ukwuu na okpomọkụ dị elu, ebe ndị ọzọ adsorbents na-emetụta nke ukwuu site na okpomọkụ.

Mmanụ aṅụ zeolite molecular sieves bụ: microporous molecular sieves na mesoporous molecular sieves.

(1) Sives molecular microporous nwere dayameta pore molekụla nke na-erughị 2nm na 2-50nm bụ sieves molekụla mesoporous (n'elu 50nm bụ sieves molekul macroporous). Mesoporous molecular sieves nwere oke elu akọwapụtara nke ọma, nhazi ọwa mgbe niile na n'usoro, nkesa nha pore dị warara, na nha pore. Njirimara nke nha na-agbanwe agbanwe na-eme ka o sie ike ịgbasa na ikewapụ macromolecules n'ọtụtụ sieves molecular microporous. ma rụọ ọrụ dị mkpa na mmeghachi omume catalytic.

(2) Mgbe ị na-ahọrọ, a ga-ahazi ihe dị iche iche sieve molekụla nwere ihe dị iche iche na nha pore dị ka akụkụ dị iche iche nke gas na-ekpofu ahịhịa iji nweta ọgwụgwọ ikuku ikuku ezubere iche, mezuo ihe a chọrọ, wee zute ụkpụrụ ikuku.

The ot mmanụ aṅụ zeolite molekụla sieve size bụ 100*100*100mm. Anyị na-enyekwa ọrụ ahaziri ahazi. Na nso nso a, onye ahịa zụtara 168 * 168 * 100mm mmanụ aṅụ zeolite molecular sieve ahaziri ahazi.
