Daim Ntawv Thov Ntawm Pseudo-boehmite Ua Adsorbent

Kev lag luam tseem ceeb ntawm macroporouspseudo-boehriteRaws li adsorbents suav nrog roj ziab, kua ziab, dej purification, xaiv adsorption thiab chromatographic cais cov txheej txheem hauv kev lag luam roj av.

Macroporous pseudo-boehrite yog dav siv nyob rau hauv roj ziab vim nws muaj zog affinity rau dej. Activated alumina tuaj yeem siv los ua kom qhuav roj feem ntau: acetylene, cracking gas thiab coke cub gas. Txij li thaum ua kom muaj alumina tso tawm ntau cov cua sov thaum nws nqus dej, lub peev xwm ziab kom qhuav, tus nqi ziab, kev sib pauv cua sov thiab kev tsim kho tshiab yuav tsum tsim.

Cov kua uas tuaj yeem qhuav los ntawm macroporous pseudo-boehmite feem ntau muaj xws li aromatics, macroolefins, roj av, kerosene, cyclohexane, propylene thiab ntau halogenated hydrocarbons. Thaum cov kua no nkag mus rau hauv alumina, lawv tsis hnov ​​​​mob lossis polymerize. Nyob rau tib lub sijhawm, cov kua qhuav tsis muaj cov khoom siv uas yooj yim adsorbed rau alumina nto thiab nyuaj rau tshem tawm thaum lub sij hawm rov tsim dua tshiab.

Macroporous pseudo-boehmite li adsorbent, catalyst li cab kuj, nws yog ib tug zoo tshuaj, kuj yog ib tug tshwj xeeb tshuaj. Kev siv sib txawv muaj qhov sib txawv ntawm cov qauv ntawm lub cev, uas yog vim li cas rau nws qhov tshwj xeeb muaj zog, ntau yam thiab hom. Raws li kev txheeb cais, tus naj npawb ntawm alumina ua catalyst thiab cab kuj tshaj tag nrho cov catalysts rau molecular sieve, silica gel, activated carbon, diatomite thiab silica aluminium gel.
