Henan Sinmat Chemical Co., Ltd. ndi m'modzi mwa opanga odalirika komanso ogulitsa zida zothandizira amorphous silika alumina ku China. Podziwa zambiri, tikukulandirani ndi manja awiri kuti mugule chothandizira chapamwamba cha amorphous silica alumina chogulitsidwa kuno kuchokera kufakitale yathu. Lumikizanani nafe zitsanzo zaulere.
Mawu Oyamba
Amorphous silica-alumina (ASA) amatanthauzidwa ngati chinthu chosakhala-crystalline aluminosilicate chopangidwa makamaka ndi silica (SiO2) ndi aluminiyamu (Al2O3), zomwe zimagwira ntchito ngati chothandizira chambiri chodziwika ndi kusinthika-kulimba kwa asidi komanso kusowa kwa-ku dongosolo la ma atomiki. Nkhaniyi imachokera ku kusakaniza kwapamtima kwa silika ndi alumina, zomwe zimapangitsa kuti asidi azitha kukhala ndi malo a Brønsted ndi Lewis acid omwe amathandiza kuti azigwiritsa ntchito njira zothandizira. Mosiyana ndi ma crystalline ma crystalline ma zeolite, chothandizira cha ASA chikuwonetsa mawonekedwe osasinthika omwe amapereka mwayi wopezeka kwa ma reactants popanda malire ophatikizika kuchokera ku ma micropores.
ASA catalyst imakonzedwa ndi sol-njira ya gel, ndi silicon ndi aluminiyumu zophatikizidwa pa sikelo ya atomiki ndikugawidwa mofanana. Monga chithandizo chapamwamba-chothandizira mapeto, chothandizira cha ASA chimakhala ndi malo a asidi ofanana, pore voliyumu yokulirapo, malo akuluakulu enieni, kugawa kwambiri, kuyera kwambiri, ndi chiŵerengero cha Si/Al chosinthika.
ASA amorphous silica-alumina, amadziwikanso kuti Amorphous Silica{1}}Alumina Xerogel, kapena kungoti ASA Xerogel. Amawoneka ngati ufa woyera. Kugwiritsa ntchito koyambirira kwa silika amorphous-alumina powder kuli ngati FCC catalyst matrix, kupereka ma mesoporous, pre-kung'amba mafuta olemera, kupititsa patsogolo kufalikira, ndi kuchulukitsa zokolola za mafuta. Imagwiranso ntchito ngati chonyamulira chothandizira hydrocracking, kutsitsa Ni, W, Mo, ndi zina. Kuphatikiza apo, ASA Xerogel ingagwiritsidwe ntchito ngati chothandizira cha isomerization, chothandizira kuchepa madzi m'thupi, ndi adsorbent.
