Cov khoom siv
Daim ntawv thov ntawm molecular sieve nyob rau hauv kev lag luam automotive yog feem ntau xav txog hauv qab no:
1, Kev kho cua sov
Molecular sieve plays lub luag haujlwm tseem ceeb hauv kev kho tsheb tsheb. Raws li ib feem ntawm kev xaiv catalytic txo (SCR) catalysts, molecularsieves tau zoo hloov nitrogen oxides (NOx) emissions los ntawm diesel xyaw rau hauv nitrogen thiab dej, yog li txo cov pa phem emissions. Piv txwv li, Cu-SSZ-13 molecularsieve tau dav siv nyob rau hauv hnyav-duty diesel tsheb reprocessing systems nyob rau hauv teb chaws Europe thiab US ua lag luam vim nws zoo heev hydrothermal stability thiab catalytic kev ua si. Tsis tas li ntawd, Beta molecularsieve kuj tseem siv tau los ua lub tsheb tso pa purification catalyst carrier khoom, pab txo cov pa phem xws li carbon monoxide (CO), nitrogen oxides (NOx) emissions.
2, Cua qhuav
Molecular sieve yog dav siv los ua desiccant vim nws cov qauv microporous zoo thiab muaj peev xwm hygroscopic. Hauv kev lag luam automotive, molecular sieve yog siv los ua cov desiccant kom nqus dej noo hauv cov cua compressed hauv lub tsheb nres tsheb kom tsis txhob nres qhov system tsis ua haujlwm los ntawm cov dej noo. Qhov no yuav pab txhim kho kev nyab xeeb ntawm lub tsheb. Molecularsieve muaj cov yam ntxwv ntawm lub peev xwm adsorption siab, siab crushing zog thiab tsis tshua muaj plua plav degree, uas yog haum rau ziab ntawm pneumatic nres tshuab xws li tsheb, tsheb loj, tsheb ciav hlau thiab nkoj.
3, VOCs kev kho mob
Nyob rau hauv kev lag luam automotive txheej, molecular sieve kuj qhia tau hais tias nws tshwj xeeb daim ntawv thov nqi. Lub zeolite molecularsieve adsorption thiab concentration runner tuaj yeem siv cov txheej txheem txuas ntxiv ntawm adsorption-desorption concentration- txias rau adsorb thiab mloog zoo rau VOCs cov pa roj pov tseg, txhawm rau kho cov tshuaj tsis haum cov organic uas ua rau hauv txheej txheej txheej txheej. Cov cuab yeej no sib txuas cov kev ua haujlwm zoo adsorption thiab rov tsim dua tshiab ntawm zeolite molecularsieve, ua rau VOCs kev kho mob zoo dua thiab zoo ib puag ncig.
4, Lwm yam kev siv
Ntxiv nrog rau cov ntawv thov tseem ceeb uas tau hais los saum no, molecular sieves muaj ntau lwm yam kev siv hauv kev lag luam tsheb. Piv txwv li, molecularsieve tuaj yeem siv rau hauv huab cua purification ntawm automotive cua txias tshuab ua lub luag haujlwm sib sib zog nqus hauv dej nqus thiab tshem tawm carbon dioxide, yog li txhim kho huab cua zoo hauv lub tsheb. Tsis tas li ntawd, nrog rau kev txhim kho lub zog tshiab tsheb, molecularsieve kuj tseem tuaj yeem pom cov ntawv thov tshiab hauv cov khoom siv roj teeb, hydrogen cia thiab lwm yam.
Hauv cov ntsiab lus, molecular sieve yog siv dav hauv kev lag luam tsheb, uas tsis yog tsuas yog pab txhim kho kev ua haujlwm ib puag ncig thiab kev nyab xeeb ntawm tsheb, tab sis kuj muab kev txhawb zog rau kev txhim kho kev lag luam tsheb. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev tswj hwm kev ua pa tawm nruj zuj zus, daim ntawv thov kev cia siab ntawm molecular sieve hauv kev lag luam tsheb yuav dav dua.
