SSZ 13 tshuaj formula:+| Ca6 (H2O)40| [Al12Si24O72]-CHAW
Kev piav qhia
1. SSZ-13 molecular sieve yog ib hom molecular sieve nrog cha topological qauv. Nws yog tsim los ntawm AlO4 thiab SiO4 tetrahedra txuas nrog oxygen atoms, tsim ib lub tawb elliptical nrog yim tus tswv cuab lub nplhaib qauv thiab peb-dimensional cross pore qauv. Qhov pore loj yog 0.38nm × 0.38nm yog lub pore me me molecular sieve. SSZ-13 molecular sieve yog tsuas yog siv nyob rau hauv kev tshem tawm NOx los ntawm automotive tso pa, methanol mus rau tsawg-carbon olefins (MTO), thiab roj sib cais adsorption, thiab nws tau qhia kev ua tau zoo.
2. Tam sim no, cov qauv siv los ua ke ssz-13 molecular sieve yog n, n, n, - trimethyl-1-adamantylammonium hydroxide cation, benzyltrimethylammonium hydroxide cation, los yog hydroxide-n, n-dimethyl{{6 }}, 5-dimethylpyridine. Txawm li cas los xij, peb cov qauv no kim heev thiab xav tau kwv yees li 1.2-2.4 tons ntawm cov qauv uas tau hais los saum no los tsim ib tuj ntawm ssz-13 molecular sieve. Muaj ob peb lub tuam txhab tsim khoom hauv tsev uas tuaj yeem tsim khoom tsim khoom, ua rau cov nqi siab rau kev sib xyaw ssz-13 molecular sieve, Kev txwv nruj heev rau nws cov khoom lag luam.
3. Cov thev naus laus zis uas twb muaj lawm tuaj yeem siv choline chloride lossis lwm tus qauv siv los ua ke ssz-13 molecular sieve, tab sis choline chloride tsis ruaj khov nyob rau hauv cov xwm txheej alkaline thiab yooj yim decomposes rau hauv trimethylamine, ethylene glycol, thiab lwm yam ntawm crystallization kub, ua rau muaj teeb meem. hauv qhov kawg ssz-13 molecular sieve. Qhov no ua rau muaj kev noj ntau ntawm cov neeg ua haujlwm template thiab cov nqi tsim khoom tsawg heev, thiab cov khoom lag luam tsis txaus siab heev, yog li txwv nws qhov kev cia siab.
4. Yog li ntawd, lub voj voog cov tshuaj tiv thaiv ntawm SSZ-13 molecular sieve yog qhov ntev, cov txiaj ntsig tau qis, thiab cov khoom siv raw khoom tseem ceeb template tus neeg sawv cev yog siv ntau thiab kim. Tseem tsis muaj kev tsim khoom loj hauv Suav teb, yog li tus nqi tsim khoom ntawm SSZ-13 molecular sieve tseem siab.
