Pob Npoo Alumina Pob Zeb (Fe2O3 AL2O3 catalyst hlaws dai) (Iron Oxide Desulfurizer) (Iron Oxide Ball) yog ib yam muaj sia nyob Claus thiab de-leak O2 tiv thaiv kev ua haujlwm ob qho tib si. Lub catalyst yog tsuas yog tsim los ntawm ib tug hloov ua kom txhij alumina carrier thiab ib qho tsim nyog tus nqi ntawm active hlau ntsev. Thaum muaj qhov de-leakage O2 nyob rau hauv cov pa roj, O2 tuaj yeem ua txoj haujlwm hloov ua rau SO2 (kev hloov dua tshiab raws li nram no):
MSO4 + 2H2S → MS2 + SO2 + 2H2O MS2 + O2 → MSO4 + SO2
Cov kab O2 uas muaj nyob hauv cov Claus txoj kev xa roj yog txo kom tsawg dua 10 ppm kom tsis txhob muaj los yog tiv thaiv cov kab mob Al2O3 los ntawm cov tshuaj lom dej lom.

Cov Lus Nug:
Q: Daim ntawv thov yog Fe2O3 AL2O3 catalyst beads?
A: Nws yog txhawb tau txais alumina. Nws yuav siv li claus catalyst, hydrated sulfur hydrolyst, titania alumina txhawb.
Q: Fe2O3 cov ntsiab lus hauv alumina hlau oxide catalyst yog dab tsi?
A: Nws yog kwv yees li 4 ~ 6%. Hauv qab 4% lossis siab tshaj 6% yog xav tshuaj. Peb yuav ua tau raws li koj cov ntaub ntawv xav tau.
