Catalytic combustion technology

1 Technical Background

Kev loj hlob ntawm kev lag luam thiab kev sib raug zoo thiab kev thov rau industrialization ua catalytic technology, tshwj xeeb tshaj yog catalytic combustion technology, nce los ua ib qho tseem ceeb kev lag luam technology txhais tau tias, thiab nrog rau kev txhim kho ntawm tib neeg txoj kev nyob thiab kev loj hlob ntawm kev thov, kev lag luam catalytic yuav txuas ntxiv mus rau ntau txhiab tus. tsev neeg, nyob rau hauv tib neeg lub neej. Txoj kev tshawb fawb ntawm catalytic combustion pib los ntawm kev tshawb pom ntawm catalytic nyhuv ntawm platinum ntawm methane combustion. Catalytic combustion plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov txheej txheem combustion, txo qhov kub ntawm cov tshuaj tiv thaiv, txhawb kev ua kom tiav, thiab inhibiting tsim cov tshuaj lom thiab teeb meem, thiab tau siv dav hauv ntau yam kev lag luam thiab kev ua neej nyob txhua hnub.

2.Lub essence thiab qhov zoo ntawm catalytic combustion

Catalytic combustion yog ib tug raug roj-kheej theem catalytic cov tshuaj tiv thaiv, nws txo cov activation zog ntawm cov tshuaj tiv thaiv nrog kev pab los ntawm cov catalyst, thiaj li hais tias nws yog flameless combustion ntawm ib tug tsawg ignition kub ntawm 200 ~ 300 ℃. Cov oxidation ntawm cov organic teeb meem tshwm sim nyob rau saum npoo ntawm cov khoom catalyst, thaum tsim CO2 thiab H2O, thiab tso tawm ntau ntawm tshav kub, vim nws tsis tshua muaj oxidation cov tshuaj tiv thaiv kub. Yog li ntawd, N2 nyob rau hauv cov huab cua yog heev inhibited tsim kub NOx. Ntxiv mus, vim qhov kev xaiv catalysis ntawm cov catalyst, nws muaj peev xwm txwv tsis pub oxidation txheej txheem ntawm nitrogen-muaj cov tebchaw (RNH) nyob rau hauv cov roj, kom lawv feem ntau tsim molecular nitrogen (N2).

Piv nrog cov nplaim taws combustion, catalytic combustion muaj qhov zoo:

(1) Lub ignition kub yog tsawg, lub zog noj yog tsawg, lub combustion yog ib qho yooj yim kom ruaj, thiab txawm lub oxidation cov tshuaj tiv thaiv yuav ua kom tiav yam tsis muaj lwm yam tshav kub hloov tom qab lub ignition kub.

(2) High purification efficiency, qis emission theem ntawm cov pa phem (xws li NOx thiab tsis tiav combustion khoom, thiab lwm yam).

(3) Cov pa oxygen loj ntau, tsis muaj suab nrov, tsis muaj kev ua qias tuaj nruab nrab, kev sib txuas nruab nrab, cov nqi khiav lag luam tsawg, thiab kev tswj xyuas yooj yim.

3 Kev Siv Technology

Cov txheej txheem ntau lawm ntawm petrochemical, xim, electroplating, luam ntawv, txheej, log tsheb thiab lwm yam kev lag luam tag nrho koom nrog kev siv thiab emission ntawm cov organic volatile compounds. Cov teeb meem tsis haum cov organic tebchaw feem ntau yog hydrocarbon tebchaw, oxygen-muaj cov organic tebchaw, chlorine, sulfur, phosphorus thiab halogen organic tebchaw. Yog hais tias cov organic tebchaw tsis hloov pauv ncaj qha mus rau hauv qhov chaw yam tsis muaj kev kho mob, lawv yuav ua rau muaj kuab paug ib puag ncig loj. Ib txwm siv cov organic pov tseg roj purification txoj kev kho mob (xws li adsorption, condensation, ncaj combustion, thiab lwm yam) muaj qhov tsis xws luag, xws li yooj yim ua rau cov pa phem thib ob. Txhawm rau kov yeej cov teeb meem ntawm cov txheej txheem kev kho cov pa roj carbon monoxide, cov txheej txheem catalytic combustion yog siv los ua kom huv cov pa roj carbon monoxide.

Catalytic combustion txoj kev yog ib tug siv tau thiab yooj yim organic pov tseg roj purification technology, lub tshuab yog lub sib sib zog nqus oxidation ntawm cov organic molecules ntawm lub catalyst rau hauv harmless carbon dioxide thiab dej txoj kev, kuj hu ua catalytic tiav oxidation los yog catalytic sib sib zog nqus oxidation txoj kev. Invention muaj feem xyuam rau lub tshuab catalytic combustion rau industrial benzene khib nyiab roj, uas siv cov nqi qis uas tsis muaj nqi hlau catalyst, uas yog tsim los ntawm CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium thiab cerium solid tov, uas. tuaj yeem txo cov tshuaj tiv thaiv kub ntawm catalytic combustion, txhim kho cov kev ua haujlwm catalytic, thiab ua kom lub neej ntev ntawm cov catalyst.Cov khoom tsim muaj feem xyuam rau cov catalytic combustion catalyst, uas yog ib qho catalytic combustion catalyst rau purification kho cov organic khib nyiab, thiab muaj ntawm lub blocky honeycomb ceramic carrier skeleton, ib txheej rau nws thiab ib tug noble hlau active tivthaiv.Cov txheej txheem ntawm catalyst yog tsim los ntawm ib tug composite oxide tsim los ntawm Al2O3, SiO2 thiab ib los yog ob peb alkaline ntiaj teb hlau oxides, yog li nws muaj zoo kub kub. tsis kam. Lub active Cheebtsam ntawm precious hlau yog loaded los ntawm impregnation txoj kev, thiab tus nqi siv tau zoo yog siab.
