Ubuchwepheshe bomlilo be-Catalytic

1 Ingemuva Lobuchwepheshe

Intuthuko yezomnotho nenhlalo yomphakathi kanye nesidingo sokusungulwa kwezimboni kwenza ubuchwepheshe be-catalytic, ikakhulukazi ubuchwepheshe bokushiswa komlilo, buqhubeke buyindlela yobuchwepheshe bemboni ebalulekile, futhi ngokuthuthukiswa kwamazinga okuphila abantu kanye nokukhula kwesidingo, imboni ye-catalytic izoqhubeka nokungena ezinkulungwaneni emakhaya, ezimpilweni zabantu. Ucwaningo lokushiswa kwe-catalytic lwaqala kusukela ekutholakaleni komphumela we-catalytic weplatinamu ekushisweni kwe-methane. Ukushiswa kwe-Catalytic kudlala indima ebaluleke kakhulu ekuthuthukiseni inqubo yokuvutha, ukunciphisa izinga lokushisa lokusabela, ukugqugquzela ukuvutha okuphelele, nokuvimbela ukwakheka kwezinto ezinobuthi neziyingozi, futhi sekusetshenziswe kabanzi ezicini eziningi zokukhiqizwa kwezimboni kanye nempilo yansuku zonke.

2.Ingqikithi kanye nezinzuzo zokuvutha kwe-catalytic

I-Catalytic combuss iyindlela evamile yegesi-solid phase catalytic reaction, inciphisa amandla okuqalisa okusabela ngosizo lwe-catalyst, ukuze ibe amandla omlilo angenalangabi ekushiseni okuphansi okungu-200 ~ 300℃. I-oxidation yezinto eziphilayo zenzeka phezu kwe-catalyst eqinile, ngenkathi ikhiqiza i-CO2 ne-H2O, futhi ikhulula ukushisa okuningi, ngenxa yokushisa kwayo okuphansi kwe-oxidation. Ngakho-ke, i-N2 emoyeni ivinjelwa kakhulu ukwakha izinga lokushisa eliphezulu i-NOx. Ngaphezu kwalokho, ngenxa ye-catalysis ekhethiwe ye-catalyst, kungenzeka ukunciphisa inqubo ye-oxidation ye-nitrogen-containing compounds (RNH) kuphethiloli, ukuze iningi lazo lenze i-nitrogen yamangqamuzana (N2).

Uma kuqhathaniswa nokushiswa komlilo okuvamile, ukuvutha kwe-catalytic kunezinzuzo ezinhle:

(1) Izinga lokushisa lomlilo liphansi, ukusetshenziswa kwamandla kuphansi, ukuvutha kulula ukuzinza, ngisho nokusabela kwe-oxidation kungaqedwa ngaphandle kokudluliswa kokushisa kwangaphandle ngemva kwezinga lokushisa lomlilo.

(2) Ukusebenza kahle kokuhlanza okuphezulu, izinga eliphansi lokukhishwa kwezinto ezingcolile (ezifana ne-NOx nemikhiqizo evuthayo engaphelele, njll.).

(3) Ibanga elikhulu lokugcwala komoyampilo, umsindo ophansi, akukho ukungcoliswa kwesibili, ukusha okusesilinganisweni, izindleko eziphansi zokusebenza, nokuphathwa kokusebenza okulula

3 Uhlelo Lokusebenza Lobuchwepheshe

Inqubo yokukhiqiza i-petrochemical, upende, i-electroplating, ukuphrinta, ukunamathela, ukukhiqiza amathayi nezinye izimboni konke kuhilela ukusetshenziswa nokuphuma kwezinhlanganisela eziphilayo eziguquguqukayo. Izinhlanganisela eziphilayo eziyingozi eziyingozi ngokuvamile ziyizinhlanganisela ze-hydrocarbon, izinhlanganisela eziphilayo eziqukethe umoya-mpilo, i-chlorine, isulfure, i-phosphorus kanye ne-halogen organic compounds. Uma lezi zinhlanganisela eziphilayo eziguquguqukayo zikhishelwa ngqo emkhathini ngaphandle kokwelashwa, zizodala ukungcoliswa kwemvelo okukhulu. Izindlela zokwelapha zendabuko zokuhlanzwa kwegesi yemvelo (ezifana ne-adsorption, condensation, ukuvutha okuqondile, njll.) zineziphambeko, njengokulula ukubangela ukungcola kwesibili. Ukuze unqobe ukukhubazeka kwezindlela zokwelashwa kwegesi yemfucuza yemvelo, indlela yokuvutha i-catalytic isetshenziselwa ukuhlanza igesi yemfucuza yemvelo.

Indlela ye-Catalytic combustion iwubuchwepheshe obusebenzayo futhi obulula bokuhlanza igesi yemvelo, ubuchwepheshe buwukukhipha i-oxidation ejulile yama-molecule e-organic ebusweni be-catalyst ibe indlela engenangozi ye-carbon dioxide kanye nendlela yamanzi, eyaziwa nangokuthi i-catalytic oxidation ephelele noma indlela ye-catalytic deep oxidation. okusunguliwe kuhlobene nobuchwepheshe bokuvutha obunamandla begesi yemfucuza ye-benzene, esebenzisa i-catalyst yensimbi engabizi kakhulu engabizi kakhulu, eyakhiwa ngokuyisisekelo i-CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium kanye nesixazululo esiqinile se-cerium, kunganciphisa kakhulu izinga lokushisa lokusabela kokuvutha kwe-catalytic, kuthuthukise umsebenzi we-catalytic, futhi kwandise kakhulu impilo ye-catalyst.Lokhu okusunguliwe kuhlobene ne-catalytic combustion catalyst, eyisisusa somlilo esiyi-catalytic sokwelashwa kokuhlanzwa kwe-organic waste gas, futhi kuhlanganisa ye-blocky honeycomb Ceramic carrier skeleton, i-coating kuso kanye nensimbi ehloniphekile esebenzayo.I-catalyst ye-catalyst yakhiwa i-oxide eyinhlanganisela eyakhiwe yi-Al2O3, i-SiO2 kanye ne-alkaline yomhlaba yensimbi oxides eyodwa noma eminingana, ngakho-ke inezinga lokushisa eliphezulu elihle. ukumelana. Izingxenye ezisebenzayo zezinsimbi eziyigugu zilayishwa ngendlela yokufakelwa, futhi izinga lokusebenzisa elisebenzayo liphezulu.
