Ho thoe'ng ka ts'ebetso ea adsorption ea 4A molecular sieve bakeng sa H₂S?E le ho rarolla bothata ba tšilafalo ea monko oa H₂S ka har'a lithōle, Re khetha li-gangue tse tala tsa mashala a theko e tlaase le kaolin, e entsoeng 4A sieve ea molek'hule e nang le adsorption e ntle le phello ea catalytic ka mokhoa oa hydrothermal.Teko e ile ea ithuta haholo phello ea mocheso o fapaneng oa calcination le nako ea crystallization ho ts'ebetso ea adsorption desulfurization.
Liphetho li bonts'a hore ts'ebetso ea adsorption desulfurization ea 4A sieve ea molek'hule e lokiselitsoeng ke kaolin e hlakile ho feta ea gangue ea mashala.Mocheso oa calcination ke 900 ℃, mocheso oa crystallization ke 100 ℃, nako ea crystallization ke 7h, 'me karolelano ea thepa le metsi ke 1: 7.Ha khatello ea alkali e le 3mol/L, matla a desulfurization a ka fihla ho 95mg/g.Tlhahlobo ea X-ray diffraction e bonts'itse hore ho ne ho na le litlhoro tse hlakileng tsa sebopeho sa sebabole ka mor'a ho phatlalatsoa ke 4A sieve ea molek'hule, e bontšang hore sehlahisoa sa 4A molek'hule sieve adsorption ea khase e nkhang hamonate ea H 2 S e ne e le sebabole sa motheo.
The 4A molek'hule sieve ka khatello ea swing adsorption ho bonolo ho chefo le ho lahleheloa ke mosebetsi oa eona, ho etsa hore thepa eohle e khaotse ho sebetsa.Li-sieve tsa limolek'hule li etsa karolo e kholo ea litšenyehelo tsa PSA, 'me litšenyehelo tse bolokiloeng tsa sete e felletseng ea lisebelisoa tsa ho matlafatsa oksijene ea limolek'hule PSA e batla e lekana le litšenyehelo tsa ho boloka matla.Lits'ebetsong tse sebetsang, khatello ea khatello ea khatello ke theknoloji e tsoetseng pele, empa thepa e theko e boima, sieve ea molek'hule e na le bophelo bo khutšoanyane ba tšebeletso, 'me thepa e entsoeng, Theko e lekana le ho boloka phaello, e leng se etsang hore limolek'hule tsa sieve khatello ea khatello e be e sa tloaelehang litšebelisong tse sebetsang.
Limolek'hule tsa carbon tse hlahisang naetrojene tsa 4A limolek'hule sieve adsorption lisebelisoa tsa adsorption li tšoaetsoa habonolo ke limolek'hule tsa metsi, likhase tse senyang, likhase tsa asiti, lerōle, limolek'hule tsa oli, joalo-joalo, tse bakang ho se sebetse ha limolek'hule.Boholo ba ts'ebetso ena ha bo khonehe.Ho kenya ts'ebetsong bocha ho ka etsoa ka ho hlatsuoa ka moea o hloekileng le metsi ha ho ratoa, empa le limolek'hule tsa khabone tse kentsoeng hape li na le ho se sebetse hantle le ho hlahisa naetrojene ho feta ea pele, e leng seo re se bitsang chefo ea molecular sieve.
