Cov hlau honeycomb substrate yog cov khoom siv honeycomb porous base ua los ntawm stainless hlau plhaub thiab corrugated FeCrAl alloy ntawv ci los ntawm coil welding txheej txheem. Nws yog siv los txhawb catalytic coatings (Pt, Pd, Rh) lossis ua raws li thermal pauv core khoom, dav siv hauv kev ntxuav tsheb pa tawm, kev kho cov roj pov tseg hauv kev lag luam, kev tiv thaiv thermal aerospace thiab lwm yam teb.
Ua los ntawm FeCrAl alloy ntawv ci, cov hlau honeycomb substrate muaj cov qauv ntom ntom, zoo li honeycomb nrog cov micro-channels sib xws - ua haujlwm zoo li "catalytic reactor" rau kev ntxuav cov pa tawm. Nws tau ntim nrog catalytic coatings thiab cov hlau zoo (Pt, Pd, Rh) thiab muaj kev tiv thaiv kub zoo heev, ua rau kev ua haujlwm ruaj khov hauv qab qhov kub thiab txias heev. Thaum cov pa tawm kub siab dhau los ntawm cov channel me me no, cov hlau zoo catalysts ua rau cov tshuaj tiv thaiv uas hloov cov pa phem mus rau hauv cov tshuaj tsis muaj teeb meem, nrog cov tshuaj tiv thaiv tseem ceeb raws li hauv qab no:
1. Kev ua pa roj carbon monoxide:2CO + O₂ = 2CO₂
2. Kev ua kom cov pa roj carbon dioxide tawm:2CxHy + (2x+y/2)O₂ = 2xCO₂ + yH₂O
3. Kev txo cov pa roj nitrogen:2NOx = N₂ + xO₂
Nrog rau kev hloov pauv cua sov sai, qhov siab qis thiab kev tiv thaiv kev co muaj zog, nws yog dav siv rau hauv kev ntxuav tsheb thiab kev kho cov roj pov tseg hauv kev lag luam.
