Tiknoolajiyada gubasho ee catalytic

1 Asalkii Farsamo

Horumarka dhaqaalaha iyo bulshada iyo baahida warshadaynta ayaa ka dhigaysa tignoolajiyada catalytic, gaar ahaan tikniyoolajiyada gubanaysa kicinta, waxay si isa soo taraysa u noqotaa tignoolajiyada warshadaha ee lagama maarmaanka ah, iyo hagaajinta heerka nolosha dadka iyo kobaca baahida, warshadaha catalytic waxay sii wadi doonaan inay galaan kumanaan guryaha, galay nolosha dadka. Daraasada gubashada catalytic waxay ka bilaabatay helitaanka saamaynta kicinta ee platinum ee gubashada methane. Gubashada catalytic waxay door aad u muhiim ah ka ciyaartaa hagaajinta habka gubashada, yaraynta heerkulka falcelinta, kor u qaadida gubasho dhamaystiran, iyo joojinta samaynta walxaha sunta ah iyo kuwa waxyeelada leh, waxaana si weyn loogu isticmaalay dhinacyo badan oo wax soo saarka warshadaha iyo nolol maalmeedka.

2.Nuxurka iyo faa'iidooyinka gubashada catalytic

Gubashada catalytic waa fal-celin gaas-adag oo caadi ah, waxay yaraynaysaa tamarta firfircoonida ee falcelinta iyadoo la kaashanayo kicinta, si ay u noqoto gubasho aan olol lahayn oo heerkul yar oo gubasho ah 200 ~ 300 ℃. oksaydhka walxaha dabiiciga ahi waxay ku dhacaan dusha sare ee kicinta adag, iyada oo la soo saarayo CO2 iyo H2O, oo sii daaya kulayl badan, sababtoo ah heerkulka falcelinta oksaydhka hooseeya. Sidaa darteed, N2 ee hawada ayaa si weyn loo xannibay si loo sameeyo heerkul sare NOx. Waxaa intaa dheer, iyada oo ay ugu wacan tahay catalysis xulashada ee kicinta, waxaa suurtagal ah in la xaddido habka oksaydhka ee xeryahooda nitrogen-ku jira (RNH) ee shidaalka, si ay intooda badan u sameeyaan nitrogen molecular (N2).

Marka la barbardhigo gubashada holac-dhaqameedka, gubashada catalytic waxay leedahay faa'iidooyin waaweyn:

(1) Heerkulka dabka ayaa hooseeya, isticmaalka tamarta waa yar yahay, gubasho waa sahlan tahay in la xasiliyo, xitaa falcelinta oksaydhka ayaa la dhamaystiri karaa iyada oo aan la wareejin kulaylka dibadda ka dib heerkulka dabka.

(2) Waxtarka nadiifinta sare, heerka qiiqa wasakhaha oo hooseeya (sida NOx iyo alaabada guban ee aan dhamaystirnayn, iwm.).

(3) Kala duwanaansho oksijiin weyn, qaylo hoose, wasakh labaad ma jirto, gubasho dhexdhexaad ah, kharashyo hawleed oo hooseeya, iyo maarayn hawleed ku habboon

3 Codsiga Farsamada

Habka wax soo saarka ee petrochemical, rinjiga, electroplating, daabacaadda, daahan, wax soo saarka taayirrada iyo warshadaha kale oo dhan ku lug isticmaalka iyo sii daayo xeryahooda kacsan organic. Iskudhisyada dabiiciga ah ee waxyeellada leh ayaa badanaa ah xeryahooda hydrocarbon, xeryahooda dabiiciga ah ee oksijiinta ku jirta, koloriin, baaruud, fosfooraska iyo xeryahooda organic halogen. Haddii xeryahooda dabiiciga ah ee kacsan si toos ah loogu sii daayo jawiga iyada oo aan la daaweynin, waxay keeni doonaan wasakh deegaan oo halis ah. Hababka daawaynta gaaska lagu sifeeyo qashinka dhaqameed ee caadiga ah (sida adsorption, condensation, gubasho toos ah, iwm.) waxay leeyihiin cillado, sida inay si sahlan u keenaan wasakhda labaad. Si looga gudbo cilladaha hababka daaweynta gaaska qashinka dabiiciga ah ee dhaqanka, habka gubashada catalytic ayaa loo isticmaalaa si loo nadiifiyo gaaska qashinka dabiiciga ah.

Habka gubashada catalytic waa tignoolajiyada nadiifinta gaaska qashinka ah ee la taaban karo oo fudud, tignoolajiyadu waa oksaydhka qoto dheer ee molecules organic on dusha sare ee kicinta galay carbon dioxide iyo habka biyaha aan waxyeello lahayn, sidoo kale loo yaqaan 'catalytic complete oxidation or catalytic deep oxidation method.The ikhtiraacida tignoolajiyada gubashada catalytic ee gaaska qashinka benzene warshadaha, kaas oo isticmaala kicinta birta ah ee aan qiimaha jaban ahayn, kaas oo asal ahaan ka kooban CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium iyo cerium xal adag, kaas oo Waxay si weyn u yareyn kartaa heerkulka falcelinta gubashada catalytic, hagaajinta dhaqdhaqaaqa kicinta, waxayna si weyn u dheereysaa nolosha kicinta. ee qalfoof sidaha dhoobada malab blocky, daahan ku dul on iyo biraha sharaf leh element.The daahan firfircoon ka kooban yahay oksaydh isku dhafan oo ay sameeyeen Al2O3, SiO2 iyo mid ama dhowr oxides biraha dhulka alkaline, sidaas darteed waxa uu leeyahay heerkulka sare wanaagsan. iska caabin. Qaybaha firfircoon ee biraha qaaliga ah waxaa lagu dhejiyaa habka impregnation, iyo heerka isticmaalka waxtarka leh waa mid sarreeya.
