Tsis ntev los no, peb tau txais ib qho kev nug txog boehmite: "Peb yog ib lub tuam txhab tshwj xeeb hauv kev tshawb fawb thiab kev tsim kho thiab tsim cov high-end catalysts. Peb tab tom nrhiav siab -purity -Al₂O₃ rau txheej txheej catalyst tshiab. Qhov tshwj xeeb ntawm thaj chaw yuav tsum tsis pub tsawg dua 250 ₂₂O % / g, Si Na 0.20 ib wt%, thiab qhov poob ntawm ignition yuav tsum ruaj khov ntawm 24-26 wt%.
Txhawm rau hais txog cov kev xav tau hais saum toj no, peb tau tsim ib qhosiab -pseudoboehmite zookhoom. Nws cov khoom zoo physicochemical ua rau nws yog ib qho zoo tshaj plaws precursor rau kev npaj siab - zoo -Al₂O₃, zoo kawg nkaus ua tau raws li cov kev cai nruj ntawm catalyst ntau lawm. Cov kev txwv tshwj xeeb thiab qhov zoo yog raws li hauv qab no:
SiO2 Tsawg dua lossis sib npaug li 0.2%
Fe2O3 Tsawg dua lossis sib npaug rau 0.03%
Na2O Tsawg dua lossis sib npaug rau 0.1%
Cov cheeb tsam tshwj xeeb loj dua lossis sib npaug li 260m² / g
Hlawv Tsawg dua lossis sib npaug rau 24%
Pore ntim 0.3-0.5ml / g
colloidal index % Ntau dua lossis sib npaug rau 97%
Zibo Xiangrunsiab -zoo boehmiteua tau raws li cov neeg siv khoom xav tau. Nws cov ntsiab lus SiO₂ yog qis dua tus neeg siv khoom lub siab txwv qhov yuav tsum tau ua rau -Al₂O₃, ua tau zoo kom tsis txhob muaj kev cuam tshuam ntawm kev ua haujlwm catalyst los ntawm silicon thiab nteg lub hauv paus rau kev npaj cov khoom qis - impurity tiav cov khoom. Los ntawm cov txheej txheem tshem tawm tshwj xeeb impurity, cov ntsiab lus sodium raug tswj tau meej, thiab tom qab calcination, Na₂O cov ntsiab lus hauv -Al₂O₃ tuaj yeem ruaj khov qis dua 0.05 wt%, ua tau raws li cov neeg siv khoom cov ntsiab lus qhia. Qhov poob ntawm qhov hluav taws kub yog ruaj khov thiab qis dua tus neeg siv khoom lub siab txwv rau -Al₂O₃, thiab lub ntim hloov pauv thaum lub sij hawm calcination yog tswj tau, uas yog qhov tsim nyog rau kev npaj cov khoom lag luam ruaj khov. Lub precursor nws tus kheej muaj qhov tshwj xeeb saum npoo; cov boehmite uas tsim los ntawm Zibo Xiangrun muaj thaj tsam ntau dua 260 m² / g, thiab tom qab calcination, qhov tshwj xeeb ntawm thaj chaw ntawm -Al₂O₃ tuaj yeem ruaj khov siab tshaj 250 m² / g, kom ntseeg tau tias muaj kev ua haujlwm catalytic.
Tsis tas li ntawd, Zibo Xiangrun lub siab -zoo pseudoboehmite muaj cov yam ntxwv zoo hauv qab no, muab tus nqi ntxiv rau koj lub tuam txhab cov txheej txheem tshiab coated catalyst: Tswj tau qhov pore ntim thiab qhov pore loj faib: Cov khoom lub pore ntim yog kho tau nyob rau hauv thaj tsam ntawm 0.3-0.5 ml / g, thiab concentrated lub pore loj yog faib. conducive rau tsim ib tug zoo-tsim thiab haum mesoporous qauv tom qab calcination. Cov qauv no muab cov kev hloov pauv huab cua zoo thiab muaj ntau qhov chaw thauj khoom qhov chaw rau cov tshuaj tiv thaiv catalytic, ua rau nws tshwj xeeb tshaj yog tsim nyog rau cov kev xav tau ntawm diffusion efficiency ntawm coated catalysts.
Zoo heev formability thiab txheej adhesion: Nrog ib tug colloidal Performance index ntawm ntau tshaj los yog sib npaug zos rau 97%, nws muaj peev xwm tsim ib tug uniform thiab ruaj khov ncua kev kawm ntawv thaum lub sij hawm catalyst slurry npaj, xyuas kom meej uniform txheej faib thiab muaj zog adhesion ntawm cov cab kuj nto, thaum kawg ua nyob rau hauv ib tug catalyst cov khoom uas muaj siab mechanical zog, uniform txheej, thiab kuj rau tev tawm.
Rau koj lub tuam txhab, uas tsom mus rau kev tshawb fawb thiab kev tsim kho thiab tsim cov qib siab -kawg coated catalysts, xaiv qhov siab -kev ua tau zoo thiab cov khoom ua ntej ruaj khov yog qhov tseem ceeb heev. Zibo Xiangrun High-Quality pseudoboehmite, nws cov purity siab, siab tshwj xeeb thaj chaw, tswj lub pore qauv, thiab zoo heev colloidal zog, tau dhau los ua cov khoom raw nyiam rau ntau yam zoo-paub cov tuam txhab hauv tsev thiab thoob ntiaj teb catalyst.
