Potassium Carbonate (formula K2CO3) yog ib qho alkaline compound feem ntau siv hauv roj av refining ua ib feem ntawm cov catalyst lossis absorbent. Nws cov kev siv tseem ceeb hauv kev kho roj av muaj xws li cov hauv qab no:
.
Cov tshuaj tiv thaiv desulfurization: Potassium carbonate tuaj yeem siv los tshem tawm cov tshuaj sulfur los ntawm cov roj, tshwj xeeb tshaj yog hydrogen sulfide (H2S) thiab carbon disulfide (CS2). Cov sulfur tebchaw no yog cov pa phem hauv cov roj uas tuaj yeem ua rau cov khoom puas tsuaj thiab ua rau muaj kev phom sij rau ib puag ncig. Potassium carbonate tuaj yeem hnov mob nrog hydrogen sulfide los ua potassium sulfide (K2S) thiab dej, yog li tshem tawm cov hydrogen sulfide.
.
.
Kev nqus pa roj acid: Potassium carbonate kuj tuaj yeem siv los nqus cov kua qaub uas tsim tawm hauv cov txheej txheem roj refining, xws li sulfur dioxide (SO2) thiab carbon dioxide (CO2). Cov pa roj no tuaj yeem ua rau cov catalysts thiab cov cuab yeej puas tsuaj thiab muaj kev cuam tshuam tsis zoo hauv ib puag ncig. Potassium carbonate reacts nrog cov kua qaub gases los tsim cov ntsev sib xws, uas pab ntxuav cov roj.
.
.
Catalyst stability: Potassium carbonate tuaj yeem siv los ua kom ruaj khov rau qee cov catalysts, tshwj xeeb tshaj yog cov tshuaj tiv thaiv nrog hydrogen thiab alkali hlau ions. Nws tuaj yeem pab tswj kev ua haujlwm ntawm cov catalyst thiab tiv thaiv kom tsis txhob muaj kab mob catalyst.
.
.
Kev kho cov tshuaj tiv thaiv kab mob: Hauv qee qhov kev cuam tshuam, potassium carbonate tuaj yeem siv los kho cov kua qaub-piv qhov sib npaug ntawm cov tshuaj tiv thaiv, yog li optimizing cov tshuaj tiv thaiv kab mob thiab ua kom cov qoob loo los yog kev xaiv ntawm cov khoom.
.
Feem ntau, kev siv cov poov tshuaj carbonate hauv roj av refining yog los pab tswj cov tshuaj tiv thaiv kab mob, txhim kho cov khoom zoo, purify cov pa roj thiab tiv thaiv catalysts. Cov ntawv thov no muaj feem xyuam rau cov khoom siv tshuaj lom neeg ntawm cov tshuaj alkaline, ua rau lawv cov neeg ua haujlwm tseem ceeb hauv ntau cov txheej txheem roj av refining. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias daim ntawv thov tshwj xeeb yuav txawv raws li cov txheej txheem sib txawv thiab kev tsim khoom.
