Mhedzisiro uye basa re template mumiriri pane synthesis yeZSM molecular sieve

Mukuita kwema molecular sieve synthesis, template mumiriri anoita basa rakakosha. Iyo template mumiriri ndeye organic molecule iyo inogona kutungamira kukura kwekristaro ye molecular sieve kuburikidza ne intermolecular kupindirana uye kuona yayo yekupedzisira kristaro chimiro.
Kutanga, iyo template mumiriri inogona kukanganisa synthesis process ye molecular sieve. Mukugadzirisa masieve emamorekuru, template agent inogona kushandiswa se "gwara" kubatsira kubatanidza mamolecular sieve nehukuru hwepore uye chimiro. Izvi zvinodaro nekuti iyo template mumiriri inokwanisa kuziva uye kurongedza kune chaiyo inorganic silicate mhando, nekudaro kudzora kutungamira kwavo uye chiyero. Kechipiri, iyo template mumiriri inogona zvakare kukanganisa saizi yepore uye chimiro cheiyo molecular sieve.
Masefa emorekuru ane saizi dzakasiyana dzepore uye maumbirwo anogona kugadzirwa neakasiyana matemplate ejenti, nekuti saizi yemamorekuru uye chimiro cheiyo template agent inotaridza saizi yepore uye chimiro cheyekupedzisira molecular sieve.
Semuenzaniso, decyl template inogona kushandiswa kugadzira ZSM-5 molecular sieve ine gumi-membered cyclopore chimiro, nepo dodecyl template inogona kushandiswa kugadzira ZSM-12 molecular sieve ine gumi nembiri-nhengo cyclopore chimiro.
Mukuwedzera, template mumiririri anogonawo kukanganisa acidity uye kugadzikana kwema molecular sieve. Mhando dzakasiyana dzema template agents anogona kupa akasiyana acidity kune molecular sieve, nekuti iyo template agent inogona kudyidzana neiyo acidic centre ye molecular sieve kuburikidza nemapoka ayo anoshanda.
Panguva imwecheteyo, akasiyana template agents anogonawo kukanganisa kugadzikana kwekupisa uye hydrothermal kugadzikana kwema molecular sieve. Semuenzaniso, kushandiswa kweamide template kunogona kuvandudza zvakanyanya kugadzikana kwekupisa kweZSM-5 molecular sieves.
Mukupedzisa, mumiriri wetemplate anoita basa rakakosha mukubatanidzwa kweZSM molecular sieve.
Nekusarudza akakodzera template mumiriri, masefa emamorekuru ane chaiyo pore saizi uye chimiro, yakanaka acidity uye kugadzikana inogona kugadzirwa, kuitira kuti isangane nezvinodiwa zvakasiyana-siyana zvinokonzeresa maitiro.
