Yaya game da aikin adsorption na sieve kwayoyin 4A don H₂S?Domin warware matsalar H₂ S wari gurbatawa a landfills, Mun zabi low-cost raw kwal gangue da kaolin aka zaba, sanya 4A kwayoyin sieve tare da kyau adsorption da catalytic sakamako ta hanyar hydrothermal hanya.Gwajin ya fi nazarin tasirin yanayin zafin ƙima daban-daban da lokacin crystallization akan aikin desulfurization adsorption.
Sakamakon ya nuna cewa aikin lalata sulfur na 4A na simintin ƙwayoyin cuta wanda kaolin ya shirya ya fi na kwal gangue a fili.A calcination zafin jiki ne 900 ℃, da crystallization zafin jiki ne 100 ℃, da crystallization lokaci ne 7h, da rabo daga abu zuwa ruwa ne 1:7.Lokacin da alkali maida hankali ne 3mol / L, da desulfurization iya aiki iya isa 95mg/g.Binciken rarrabuwar kawuna na X-ray ya nuna cewa akwai fayyace kololuwar halayen sulfur a cikin bakan bayan adsorption ta hanyar sieve na kwayoyin 4A, yana nuna cewa samfurin 4A na simintin sikelin ƙwayoyin cuta na H 2 S iskar gas mai kamshi ne sulfur.
Sivewar kwayoyin 4A a cikin tallan jujjuyawar matsa lamba yana da sauƙin guba kuma ya rasa aikinsa, yana haifar da duka kayan aikin su daina aiki.Sives na kwayoyin halitta suna da babban kaso na farashin PSA, da kuma tanadin kuɗin da ake samu na cikakken saitin na'urorin haɓaka iskar oxygen na PSA kusan daidai da farashin ceton makamashi.A aikace aikace-aikace, matsa lamba lilo adsorption ne ci-gaba fasaha, amma kayan aiki ne mai tsada, da kwayoyin sieve yana da wani gajeren sabis rayuwa, da kuma kayayyakin kerarre, Farashin daidai riba tanadi, wanda ya sa kwayoyin sieve matsa lamba lilo adsorption rare a m aikace-aikace.
Kwayoyin carbon da ke samar da nitrogen na 4A kwayoyin sieve matsa lamba na kayan tallan kayan aiki suna samun sauƙin kamuwa da kwayoyin ruwa, iskar gas mai lalata, gas ɗin acid, ƙura, ƙwayoyin mai, da sauransu, wanda ke haifar da rashin kunnawa kwayoyin.Yawancin wannan rashin kunnawa ba zai iya jurewa ba.Ana iya sake kunnawa ta hanyar zubar da iska da ruwa mai kyau idan ana so, amma ko da sake kunnawa da sake kunna carbon suna da ƙarancin aiki da samar da nitrogen fiye da na asali, wanda shine abin da muke kira guba na sieve kwayoyin.
