Pseudoboehmite
Jun 20, 2022
Cov yam ntxwv ntawm pseudo boehmite:
Pseudo boehmite yog cov khoom tsis muaj tshuaj lom, tsis qab thiab tsw ntxhiab dawb colloidal (ntub) lossis hmoov (qhuav) khoom. Nws muaj qhov me me me me, siab pore ntim, thaj chaw loj tshwj xeeb, zoo gel solubility thiab siab siv lead ua purity. Nws muaj cov yam ntxwv ntawm thixotropic gel thiab soluble heev hauv cov kua qaub thiab alkalis. Cov hmoov qhuav muaj hygroscopic tshwm sim thaum raug huab cua.
Daim ntawv thov tseem ceeb ntawm pseudo boehmite:
1. Aluminium qhov chaw rau binder thiab molecular sieve synthesis nyob rau hauv petrochemical thiab refining catalyst industries
Pseudo boehmite feem ntau yog siv los ua FCC catalyst li binder. Pseudo boehmite li binder tuaj yeem tsis tsuas yog txhim kho lub zog ntawm cov catalyst, tab sis kuj kho qhov pore loj faib ntawm cov catalyst, txhim kho thermal thiab hydrothermal stability ntawm catalyst, kho qhov ntom ntawm acid active qhov chaw ntawm catalyst, thiab txhim kho cov catalytic. kev ua si.
2. siv los ua catalyst cab kuj
Pseudo boehmite yog dav siv los ua catalyst cab kuj nyob rau hauv ntau yam tshuaj, roj refining thiab petrochemical tshuaj. Cov piv txwv yog hydrofining catalyst carrier, hloov kho catalyst cab kuj, methanation catalyst cab kuj, thiab lwm yam. Pseudo boehmite ua - Alumina kuj yuav siv tau raws li ib tug catalyst.
