Okwu Mmalite na Ihe Ndị Na-akpata Mbelata Catalytic Nhọrọ (SCR) Catalysts

Nhọrọ nke mbelata catalytic (SCR) na-eji onye na-ebelata ihe na-emeghachi omume na NOx na flue gas, na-emepụta ihe na-adịghị - na-egbu egbu na mmetọ {{1} N2 na H2O n'efu, n'okpuru ọrụ nke ihe mkpali.

Okpomọkụ mmeghachi omume na-ekpebi ọ bụghị naanị mmeghachi omume mmeghachi omume nke ndị na-emeghachi omume kamakwa mmeghachi omume nke SCR catalyst. N'ozuzu, elu mmeghachi omume okpomọkụ na-ebute ngwa ngwa mmeghachi omume ọnụego na elu catalyst ọrụ, na-eduga a nta mmeghachi omume ohere na reactor olu kwa otu mpaghara. N'ịtụle ikpo ọkụ reactant, njikwa sistemu, yana oke okpomọkụ dabara adaba nke ihe mkpali, a na-edobe okpomọkụ sistemu SCR n'etiti ogo 320 na 420.

Ọsọ oghere bụ isi ihe eji emepụta ihe maka mbelata catalytic nhọrọ (SCR). Ọ tụrụ oge obibi nke flue gas (mmiri flue gas n'okpuru ọkọlọtọ ọnọdụ) n'ime catalyst olu, na ruo n'ókè ụfọdụ na-ekpebi ma reactants-emeghachi omume kpamkpam. Ọ na-emetụtakwa nlegharị anya nke usoro ihe na-akpata reactor na mfu nke gas flue.

Ịdị mma nke usoro mgbaba ọkụ ọkụ na-ekpebi ịdị irè nke ihe na-akpata. Usoro ịgbasa flue gas kwesịrị ekwesị ọ bụghị naanị na-ebuli ojiji ihe na-akpali akpali ma na-ebelata mfu esemokwu. N'ime imepụta injinia, a ga-enyocha nke ọma ebe a na-agbapụta flue gas. Ebe ịgba ọgwụ mgbochi Amonia kwesịrị inwe ọnọdụ ọgba aghara iji nweta ngwakọta kacha mma na gas flue wee mepụta mpaghara na-asọ asọ nke akọwapụtara nke ọma.
