Pseudo-boehmite yog dab tsi
Jan 30, 2023
Pseudo-boehmite, uas yog, SB hmoov (Al2O3·nH2O lossis, AlOOH·H2O n=0.08 -- 0.62) Lus Askiv lub npe pseudo-Boehmite, lus Askiv abbreviation PB. Pseudo-boehmite, gelatinous boehmite, los yog pseudo-boehmite, yog ib hom kev hloov khoom siv los ntawm kev tsis sib haum xeeb mus rau kev txiav txim thiab tsis muaj zog crystalline mus rau crystalline nrog tsis paub meej muaj pes tsawg leeg thiab tsis tiav crystallization. Nws cov qauv siv lead ua zoo ib yam li Boehmite, tab sis nws cov siv lead ua me me thiab tsis zoo hauv crystallinity. Cov qauv tsim yog nyias nyias thiab folded lamellar siv lead ua. Nws yog non-toxic, tasteless, ntxhiab tsw dawb colloidal (ntub) los yog hmoov (qhuav) khoom, me me particle loj, siab pore ntim, loj tshwj xeeb deg cheeb tsam, zoo colloidal solubility, siab purity ntawm crystal theem, nrog rau cov yam ntxwv ntawm thitropic. gel, yooj yim rau yaj nyob rau hauv muaj zog acid, muaj zog puag, qhuav hmoov raug rau huab cua muaj hygroscopic phenomenon.
Hauv kev lag luam petrochemical thiab tshuaj lom neeg niaj hnub no, ntau dua 90 feem pua ntawm cov tshuaj tiv thaiv tshuaj raug pom los ntawm cov catalysts. Catalysts kuj tau siv dav hauv kev txhim kho lub zog tshiab, kev siv dav dav ntawm cov peev txheej thiab kev tswj hwm ib puag ncig. Muaj ntau hom thiab ntau npaum li cas ntawm cov catalysts. Tsis muaj teeb meem cov khoom siv hluav taws xob siv hauv cov roj refining, kev lag luam petrochemical lossis kev lag luam tshuaj zoo, yuav tsum muaj cov nqa khoom. Activated alumina carriers suav txog li 57 feem pua hauv kev lag luam catalyst carrier. Pseudo-boehite, raws li cov khoom siv tseem ceeb rau kev npaj cov khoom siv alumina, ua lub luag haujlwm tseem ceeb hauv kev lag luam catalyst. Tus nqi ntawm pseudo-boehrite hauv catalyst ntau lawm suav txog 20 feem pua ntawm tag nrho. Nyob rau hauv xyoo tas los no, Sinopec Changling Oil Refining Co., LTD., Catalyst Plant ntawm Qilu Petrochemical Company thiab Catalyst Plant ntawm Lanzhou Roj Refining thiab Chemical Company tau rov tsim kho thiab nthuav tawm cov kab tshiab, thiab qhov kev thov rau pseudo-bauxite tau nce ntxiv. Tebchaws Asmeskas, Western Europe thiab Nyij Pooj yog lub ntsiab catalyst tsim tawm txawv teb chaws.
Daim ntawv thov tseem ceeb:
1. Siv raws li ib qho txhuas qhov chaw rau binder thiab molecular sieve synthesis nyob rau hauv petrochemical thiab refining catalyst industries
Pseudo-boehmite feem ntau yog siv los ua catalytic cracking catalyst raws li ib tug binder. Pseudo-boehmite raws li ib tug binder tsis tau tsuas yog txhim kho lub zog ntawm catalyst, tab sis kuj kho lub pore loj faib catalyst, txhim kho lub thermal thiab hydrothermal stability ntawm catalyst, kho qhov ceev ntawm catalyst acid active chaw, thiab txhim kho cov catalytic kev ua si.
2. Siv ua catalyst cab kuj
Pseudo-boehmite yog dav siv nyob rau hauv tshuaj, roj refining thiab petrochemical tshuaj raws li catalyst cab kuj, nws cov piv txwv xws li hydrorefining catalyst carrier, hloov kho catalyst cab kuj, methanation catalyst cab kuj, thiab lwm yam. kuj tseem siv los ua ib qho catalyst.
Peb lub tuam txhab tshwj xeeb hauv kev tsim cov purity pseudo-boehmite nrog purity ntau dua 99.9 feem pua. Nyob rau tib lub sijhawm, peb tuaj yeem kho qhov pore ntim, aperture thiab thaj chaw tshwj xeeb ntawm purity pseudo-boehmite raws li cov neeg siv khoom xav tau.
