Henan Sinmat Chemical Co., Ltd. ndi amodzi mwa opanga odalirika komanso ogulitsa zeolite catalyst day-60 ku China. Ndi zokumana nazo zambiri, tikukulandirani ndi manja awiri kuti mugule zeolite chothandizira tsiku-60 zogulitsa kuno kuchokera kufakitale yathu. Lumikizanani nafe zitsanzo zaulere.
Mawu Oyamba
Zeolite catalyst DAY-60 ndi mtundu wa Dealuminated Ammonium Y-mtundu (DAY) sieve ya molecular, yokhala ndi silica yayikulu-to{5}}alumina ratio ya 60. Imasunganso FAU topology ndi three-dimensional macropores (macropores atatu).
Poyerekeza ndi TSIKU-30, TSIKU-zeolite 60 ili ndi aluminiyamu yocheperako, chimango chokhazikika, ndipo imapeza bwino pakati pa acidity ndi kukhazikika kwa hydrothermal. TSIKU-60 zeolite chothandizira chimakhala ndi chiŵerengero chapamwamba cha silica-to-alumina, zomwe zimapangitsa kuti malo ocheperako azikhala ochepa komanso mphamvu za asidi. Komabe, chimango chake chozama kwambiri chimakhala chokhazikika, motero chikuwonetsa kukana kwamphamvu kwa hydrothermal ndikutha kupirira mikhalidwe yosinthika ya FCC (pamwamba pa digirii 700).
Kuphatikiza apo, mawonekedwe a macroporous a DAY-60 zeolite catalyst ndi oyeneranso kuchitapo kanthu kwa mamolekyu akulu pakusweka kwamafuta olemera. Ndipo mawonekedwe ake okometsedwa a pore, kupanga pang'ono ma mesopores achiwiri, omwe amatha kupititsa patsogolo kufalikira. TSIKU-60 kwenikweni ndi chothandizira champhamvu cha USY zeolite chomwe chakhala chikuchitika ndi chithandizo chokhazikika.
DAY-60 zeolite ndiye chothandizira chachikulu cha FCC, chomwe chimagwiritsidwa ntchito kwambiri pakusweka kwamadzimadzi kuti apititse patsogolo zokolola zamafuta, kutulutsa kwa olefin wopepuka, komanso kukana kuipitsidwa kwachitsulo. Nthawi zina, imagwiranso ntchito ngati chithandizo cha asidi mu hydrocracking, kupereka mphamvu zowonongeka. Mu petrochemical deep processing, DAY-60 imakhalanso ndi ntchito zofunika, monga kutembenuza mafuta olemera ndi kukweza dizilo.
