Li-sieve tsa limolek'hule tsa Zeolite li bapala karolo ea bohlokoa ts'ebetsong ea tlhahiso ea haedrojene ea PSA (Pressure Swing Adsorption), 'me thepa ea bona ea ho khetha ke senotlolo sa ho fihlela tlhoekiso ea haedrojene. Tlhahiso ea haedrojene ea PSA ke ts'ebetso ea 'mele ea adsorption, ke ts'ebetso ea karohano ea khase e sebelisang matla a fapaneng a adsorption ea likhase tse fapaneng ho molecular sieve adsorbent.
Mokhoa oa ho Hloekisa Hydrogen o Joang?
Joalo ka ha haedrojene e sebelisoa makaleng a mangata a indasteri le matla, haholo liseleng tsa mafura le indastering ea lisebelisoa tsa elektroniki, li na le litlhoko tse thata haholo, ke hydrogen e hloekileng feela e ka fihlelang litlhoko tsena.
Empa haedrojene e hlahisoang ke lintho tse tala hangata e na le mouoane oa metsi le litšila tse kang carbon monoxide, carbon dioxide, methane, khase ea nitrogen le sulfide. Metsi le litšila tsena li ka chefo li-catalyst, tsa fokotsa ts'ebetso e sebetsang hantle, tsa senya lisebelisoa le ho beha likotsi tsa polokeho. Ka hona, lits'ebetso tse amanang le tlhoekiso ea haedrojene li shebana haholo le ho omisa le ho tlosa litšila.
PSA Hydrogen Production Le Tlhoekiso
Tlhahiso ea hydrogen ea PSA ke e 'ngoe ea mekhoa e sebelisoang haholo ea ho hloekisa haedrojene indastering. Haholo-holo e loketse ho hloekisa haedrojene-e nang le likhase tse tsoakiloeng joalo ka gase ea coke oven le syngas (ho fetola khase ea tlhaho, ho tlatsa mashala).
PSA hydrogen purification e sebelisa mefuta e fapaneng ea khetho ea adsorption ea li-sieve tsa molek'hule tlas'a khatello e phahameng, ho arola haedrojene ho khase e tsoakiloeng. Lisele tse lekanang tsa masoba tsa li-sieve tsa limolek'hule li li lumella ho tšoasa limolek'hule tse nyane tsa litšila, 'me li lokolle limolek'hule tse kholoanyane tsa haedrojene.
