Porous Ceramic Ball Chaw Tsim Tshuaj nrog qhov sib txawv

Porous ceramic balls tseem hu ua filtering balls.Nws yog tsim los ntawm ua 20-30% pores nyob rau hauv lub inert ceramic pob.Yog li nws tuaj yeem siv tsis tau tsuas yog rau kev txhawb nqa thiab npog cov catalyst, tab sis kuj rau kev lim thiab tshem tawm cov impurities ntawm nplej, gelatin, asphalting, hnyav hlau thiab hlau ions tsawg dua 25um.Yog hais tias lub pob ntxeem tau teem rau sab saum toj ntawm lub reactor, cov impurities tsis raug tshem tawm hauv cov txheej txheem qub tuaj yeem raug adsorbed hauv cov pores hauv cov khoom, muaj raws li kev tiv thaiv cov catalyst thiab ua kom lub sijhawm ua haujlwm ntawm lub cev.Raws li cov impurities tam sim no. hauv cov ntaub ntawv sib txawv, tus neeg siv tuaj yeem xaiv cov khoom los ntawm lawv qhov ntau thiab tsawg, qhov pores thiab porosity, lossis yog tias tsim nyog, ntxiv molybdenum, npib tsib xee thiab cobalt lossis lwm yam khoom siv los tiv thaiv cov catalyst los ntawm coking lossis lom.

Daim ntawv thov

Porous ceramic pob yog ib yam khoom tshiab tsim los ntawm inert alumina ceramic pob.Nws yuav siv txoj kab uas hla ntawm lub pob raws li axis los qhib lub qhov.Nws tsis tsuas yog muaj qee yam kev siv zog, tshuaj lom neeg ruaj khov thiab thermal stability, tab sis kuj ua rau cov cheeb tsam tshwj xeeb.Thiab qhov tsis muaj qhov sib piv, yog li ua kom cov dispersion thiab flux ntawm cov khoom, thiab txo qhov tsis kam ntawm qhov system.Nws tuaj yeem siv dav hauv kev lag luam roj av, tshuaj lom neeg thiab cov pa roj carbon monoxide los hloov inert alumina ceramic npas li catalyst npog cov khoom siv.
