Aikace-aikace da kira na ZSM-5 kwayoyin sieve

I. Gabatarwa

ZSM-5 kwayoyin sieve wani nau'i ne na microporous abu tare da tsari na musamman, wanda aka yi amfani da shi sosai a wurare da yawa saboda kyawawan kaddarorin sa, kwanciyar hankali da aikin catalytic.A cikin wannan takarda, za a gabatar da aikace-aikace da haɗin gwiwar simintin kwayoyin ZSM-5 daki-daki.

Na biyu, aikace-aikace na ZSM-5 kwayoyin sieve

1. Catalyst: Saboda babban acidity da kuma tsarin pore na musamman na ZSM-5 na simintin kwayoyin halitta, ya zama mai mahimmanci ga yawancin halayen sinadaran, irin su isomerization, alkylation, dehydration, da dai sauransu.
2. Adsorbent: ZSM-5 kwayoyin sieve yana da babban ƙarar pore da kyakkyawan aikin adsorption, kuma ana amfani da shi sosai a cikin rabuwar gas, rabuwar ruwa da mai kara kuzari da sauran filayen.
3. Catalyst carrier: za a iya amfani da shi azaman mai ɗaukar hoto don inganta aiki da kwanciyar hankali.

Haɗin kai na ZSM-5 na kwayoyin halitta yawanci yana ɗaukar hanyar samfuri, wanda ke sarrafa tsarin kira ta hanyar sarrafa zafin jiki, matsa lamba, rabon albarkatun ƙasa da sauran yanayi.Daga cikin su, kayan da aka fi amfani da su sune sodium silicate da sodium aluminate.

1. Sarrafa silica-aluminum rabo: silica-aluminum rabo ne daya daga cikin muhimman sigogi na ZSM-5 kwayoyin sieve, wanda za a iya sarrafawa ta daidaita rabo na sodium silicate da sodium aluminate.Mafi girman rabon siliki zuwa aluminium, mafi girman tsarin tsarin sieve kwayoyin halitta shine silicon, kuma akasin haka.
2. Tsarin zafin jiki da matsa lamba: haɗuwa da zafin jiki da matsa lamba kuma sune mahimman abubuwan da suka shafi samuwar ZSM-5 kwayoyin sieve.Gabaɗaya, yanayin zafi mafi girma da matsin lamba suna dacewa don ƙirƙirar sieves na kwayoyin ZSM-5.
3. Crystallization lokaci da crystallization zafin jiki: crystallization lokaci da crystallization zafin jiki ne muhimman al'amurran da suka shafi tsarin ZSM-5 kwayoyin sieve.An inganta ƙimar samuwar da tsarkin simintin kwayoyin ZSM-5 ta hanyar ƙara yawan zafin jiki a lokacin da ya dace.

A matsayin wani muhimmin microporous abu, ZSM-5 kwayoyin sieve yana da fadi da aikace-aikace bege.Yana da mahimmanci a fahimci hanyar haɗakarwa don aikace-aikacensa mai faɗi.Ta hanyar sarrafa yanayin kira, tsarin pore, acidity da catalytic Properties na ZSM-5 kwayoyin sieve za a iya daidaita su yadda ya kamata, wanda ke ba da ƙarin damar yin amfani da shi a fannoni daban-daban.
