ʻO Henan Sinmat Chemical Co., Ltd. kekahi o nā mea hana hilinaʻi a me nā mea hoʻolako o ka zeolite catalyst ssz-13 ma Kina. Me ka ʻike nui, mahalo mākou iā ʻoe e kūʻai i ka zeolite catalyst ssz-13 kiʻekiʻe no ke kūʻai aku ma ʻaneʻi mai kā mākou hale hana. E kelepona mai iā mākou no ka hāpana manuahi.

ʻO SSZ-13 catalyst, he kānana molekula ʻano CHA me ʻewalu -pores apo ʻokoʻa, a ʻo ia kekahi o nā kānana molekala koʻikoʻi i ka catalysis kaiapuni, ʻo ia hoʻi i loko o ka diesel vehicle exhaust denitrification (SCR). Ua lilo ʻo SSZ-13 i ka maʻamau ʻoihana ma nā ʻōnaehana catalyst NH₃-SCR.
SSZ-13 molecular sieve he ekolu-dimensional cross-pore structure system, e hiki ai i ka NH₃, NO, a me NO₂ ke komo i ka wa e keakea ana i ke komo ana o SO₂ oxides nui a me hydrocarbons, pela e hoike ana i ke kupaa maoli i ka make. Aia kona loko i nā hīnaʻi CHA maʻamau, hoʻopaʻa paʻa i nā ion metala e like me Cu²⁺ a me Fe³⁺ i loko o kēia mau hīnaʻi, ʻo ia ke kumu nui o kona kūʻē ʻana i ka ʻelemakule hydrothermal a me ke kūpaʻa wela kiʻekiʻe.
ʻO SSZ-13 SCR catalyst ka mea holomua loa i ka hoʻopau kinoea denitrification i kēia mau lā, he kānana molekala kūikawā i hoʻolālā ʻia no NH₃-SCR. Ma muli o kona kūpaʻa hydrothermal maikaʻi loa a me kahi kikoʻī kikoʻī kiʻekiʻe, hōʻike pū ia i ka hana koʻikoʻi i ka methanol i olefins (MTO) a me ka hoʻokaʻawale ʻana i ke kinoea adsorption.
