Cov catalyst hauv lub cav tso pa tawm yog lub hollow hlau qauv nrog ib txheej txheem pob zeb ua ke cov qauv sab hauv. Vim tias muaj qhov chaw ntawm thaj chaw sib chwv sib txuas ntxiv uas cov pa pa tawm, cov roj hluav taws nyob hauv nws tau oxidized thiab hlawv tawm. Vim li ntawd, qhov ntau npaum li cas ntawm cov pa paug ntawm cov khoom phem rau hauv cov cua tau txo tsawg.

Cov Lus Qhia
Kauj ruam 1
Vim tias qhov tseeb ntawm tus nqi ntawm thawj catalysts hauv kev muag khoom yog qhov ntau heev vim yog cov ntsiab lus ntawm cov khoom muaj nqi, xws li platinum, palladium, thiab lwm yam, hauv lawv cov honeycomb ceramic. cov pa tso tawm, yuav cov khoom qub uas tsis yog qub los hloov nws (lawv cov pheej yig dua) lossis cov ntes nplaim taws. Qhov kev xaiv yooj yim tshaj plaws yog mus khob tawm lub honeycomb ntawm lub tom qab.
Kauj ruam 2
Cov laj thawj uas qhia tias muaj kev cuam tshuam ntawm cov catalyst yog:
- qhov poob ntawm lub zog ntawm lub cev muaj zog vim yog txoj kev nyuaj dhau ntawm roj los ntawm kev sib npws honeycombs,
- ib qho yooj yim ntxiv rau rattling suab los hauv qab ntawm lub tsheb, tsim los ntawm tej daim ntawm cov hniav sib tsoo hauv lub cev ntawm lub cuab yeej.

Tom qab cov tsos ntawm cov phiajcim no, lub tshuab tso rau ntawm qhov chaw kuaj xyuas, hla lossis nqa khoom. Hauv qab ntawm lub tsheb, lub pob zeb catalyst txuas yog tsis muaj peev xwm, uas, raws li txoj cai, tau nruab rau hauv lub kaw lus siv cov flanges lossis crimping clamps.
Kauj ruam 4
Muaj kev tso tawm ib qho ntawm lub cev tso pa tawm, nws raug tshem tawm los ntawm lub tshuab, thiab lub xeev ntawm cov kab ua haujlwm honeycomb raug tshuaj xyuas ntawm lub tshuab xauv pob kws ua haujlwm. Yog tias lawv tau txhaws los yog yaj tag, tom qab ntawd cov nplais pob txha kiag li tawm hauv lub cev nrog tus rauj thiab txaug.
