Tsis tshua muaj ntiaj teb catalytic cov ntaub ntawv

Lo lus 'catalyst' tau siv txij thaum 19 xyoo pua, tab sis nws tau sib txawv dua rau xyoo 1970 Ua ntej ntawd, nws ua lub luag haujlwm tseem ceeb hauv qhov tob ntawm cov nroj tsuag tshuaj uas tib neeg tsis tuaj yeem saib, ntsiag to tab sis txuas ntxiv rau xyoo lawm. Nws yog cov ncej loj loj ntawm cov tshuaj lom neeg kev lag luam, thiab nrog kev tshawb nrhiav ntawm cov tshuaj tshiab, qhov loj-teev tshuaj lom neeg muaj kev lag luam tsis tau mus txog rau kev lag luam ntsig txog kev lag luam. Piv txwv li, qhov kev tshawb pom thiab kev siv cov hlau catalysts tso lub hauv paus rau cov petrochemical thiab polymer synthesis kev lag luam. Qhov tseeb, qhov kev thov ntxov tshaj plaws ntawm kev tsis tshua muaj lub ntiaj teb tseem pib nrog catalysts. Xyoo 1885, Austrian Cav Welsbach impreghiver ib nitric acid daws 99% thiab 1% CEO2 ntawm Asbestos los ua kev lag luam ntawm chav tsim khoom ntawm chav tsim khoom ntawm stubshades.

Tom qab ntawd, nrog kev txhim kho kev lag luam tshuab thiab kev sib tw ntawm kev tshawb fawb ntawmTsawg lub ntiaj teb, Nws tau pom tias vim yog cov nyhuv zoo ntawm cov av hauv av tsawg thiab lwm yam khoom siv hlau ua los ntawm lawv tsis tsuas yog anti lom kev ua tau zoo thiab muaj kev ruaj khov. Lawv muaj ntau nplua nuj nyob rau hauv cov peev txheej, pheej yig dua nyob rau hauv kev ua tau zoo dua li cov khoom siv uas muaj nqis, thiab tau dhau los ua lub zog tshiab hauv cov chaw catalytic. Tam sim no, tsis tshua muaj dav siv nyob rau ntau thaj teb, tshuaj lom neeg, kev ua pa hluav taws xob, thiab roj av catalytic combustion. Kev siv ntawm lub ntiaj teb tsawg hauv thaj teb ntawm catalytic cov ntaub ntawv nyiaj txiag rau kev sib koom. Tsoomfwv Meskas noj cov feem ntau ntawm cov tseem ceeb hauv lub ntiaj teb hauv catalysis, thiab Tuam Tshoj kuj noj ntau npaum li cas rau hauv thaj chaw no.

Tsis tshua muaj cov ntaub ntawv catalytic tseem ua kom dav siv nyob rau hauv cov chaw ib txwm muaj xws li roj av thiab cov tshuaj engineering. With the enhancement of national environmental awareness, especially with the approaching of the Beijing 2008 Olympics and Shanghai 2010 World Expo, the demand and application of rare earth catalytic materials in environmental protection, such as automotive exhaust purification, natural gas catalytic combustion, catering industry oil fume purification, industrial exhaust gas purification, and the elimination of volatile organic waste gas, will definitely increase significantly.
