Zeolite Catalyst REY

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

ʻO ka zeolite catalyst REY (Rare Earth Y) a i ʻole REY molecular sieve he ʻano Y{0}}type zeolite i loaʻa ma ka hoʻololi ʻana i ka zeolite NaY ma o ka hoʻololi ʻana i nā ion, e hoʻololi ana i kekahi a i ʻole nā ​​​​iona sodium āpau me nā ion metala honua laha loa (e like me La³⁺, Ce³⁺, Nd³⁺, Pr³⁺, etc.). Loaʻa iā REY zeolite kahi hoʻolālā FAU, me ke anawaena pore ma kahi o 0.74 nm, a ʻike ʻia me he pauda keʻokeʻo.

Loaʻa iā REY molecular sieve nā mea maikaʻi o Y-type molecular sieve, e like me ka ratio silica-alumina kiʻekiʻe, kahi ʻano like ʻole a me ka hoʻolālā pore maʻamau, a me kahi ili nui. Eia kekahi, ʻo ka hoʻokomo ʻana i nā mea o ka honua laha ʻole e hoʻoikaika i nā kikowaena waikawa, e hiki ai i ka catalyst ke kiʻekiʻe o ka hana mua a me ka acidity, kahi mea e pono ai no ka hana ʻana.

Hoʻohana nui ʻia ʻo REY molecular sieve i loko o ka petroleum catalytic cracking reactions. Hiki iā ia ke hoʻonui i ka nui o ka hopena a me ka koho, hoʻemi i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai, a kūpono loa ia no ka hoʻomaikaʻi ʻana i ka helu hoʻololi ʻana o ka ʻaila ʻaila a hoʻonui i ka hua o ka ʻaila a me ka diesel.
