1 Physisorption. … Lub cev adsorption tshwm sim sai vim nws tsis tas yuav muaj lub zog ua kom muaj zogTxawm li cas los xij, qeeb uptake yuav raug soj ntsuam ntawm cov ntxeem tau zoo xws li zeolites thiab qee cov pa roj carbon diffusion txwv tsis yog cov txheej txheem sorption nws tus kheej..
Lub hom phiaj twg yog lub luag haujlwm rau lub cev?
Physisorption (los yog lub cev adsorption) yog adsorption uas cov rog koom nrog yog intermolecular rog (van der Waals rog)ntawm tib yam li cov neeg ua haujlwm rau qhov tsis zoo ntawm cov roj ntsha tiag thiab condensation ntawm vapors, thiab uas tsis cuam tshuam qhov kev hloov loj.
Yuav ua li cas lub zog siv tau rau hauv lub cev adsorption?
Lub zog ua kom muaj zog ntawm adsorption Ea rau lub cev adsorption yog 5∼40 kJ / mol, thaum lub zog ua kom muaj zog ntawm adsorption Ea rau cov tshuaj adsorption yog 40∼800 kJ / mol.
Tus txheej txheem ntawm physisorption yog dab tsi?
Physisorption yog lub cev sib txuas ntawm cov roj molecules rau saum npoo ntawm cov khoom lossis cov kua uas cov roj nkag mus rau hauv qhov kub thiab txias. Qhov no tshwm sim vim Van der Waals rog. … Physisorption tseem hu ua lub cev adsorption.
Vim li cas chemisorption xav tau lub zog ua kom siab?
Teb: Chemisorption hu ua activated adsorption vim nws koom nrog kev tsim tshuaj lom neeg ntawm reactant thiab adsorbent molecules. Tsim cov tshuaj tiv thaiv xav tau lub zog ua kom muaj zog Yog li, nws tau qhib rau ntawm qhov kub thiab txias.
