Henan Sinmat Chemical Co., Ltd. ndi amodzi mwa opanga odalirika komanso ogulitsa zeolite chothandizira ssz-13 ku China. Podziwa zambiri, tikukulandirani ndi manja awiri kuti mugule zeolite chothandizira ssz-13 zapamwamba zogulitsa kuno kuchokera kufakitale yathu. Lumikizanani nafe zitsanzo zaulere.
Mawu Oyamba
SSZ-13 catalyst, ndi CHA structure type molecular sieve with unique eight-emember pores ring pores, and is one of the most important sieves of ma molecular catalysis, makamaka mu dizeli galimoto exhaust denitrification (SCR). SSZ-13 yakhala muyezo wamakampani muzinthu zothandizira za NH₃-SCR.
SSZ-13 sieve ya molekyulu imakhala ndi-njira zitatu zopingasa{4}}zopanga pore, zomwe zimalola NH₃, NO, ndi NO₂ kulowa kwinaku akulepheretsa kulowa kwa ma SO₂ oxides ndi ma hydrocarbons akulu, motero amawonetsa kukana poizoni. Mkati mwake muli makola a CHA okhazikika, omangika mwamphamvu ma ion achitsulo monga Cu²⁺ ndi Fe³⁺ mkati mwa makolawa, chomwe ndi chifukwa chachikulu chomwe chimakanira kukalamba kwa hydrothermal komanso kukhazikika kwa kutentha kwambiri.
SSZ-13 SCR catalyst ndiyo njira yopambana kwambiri yochotsera gasi masiku ano, ndi sieve yapaderadera yopangidwira NH₃-SCR. Chifukwa cha kukhazikika kwake kwa hydrothermal komanso malo apamwamba kwambiri, ikuwonetsanso magwiridwe antchito apamwamba mu methanol to olefins (MTO) komanso kupatukana kwa gasi adsorption.
