L’aulina ła doparava come portałixador catałista el pol esar riassumentà inte i seguenti tipi secondo ła so proprietà fisica e chimica e el ruoło xogà da l’aumina:
(1) High temperature alumina carrier. This type of alumina has a small specific surface area, high temperature resistance, chemical resistance and high mechanical strength, so it can withstand harsh operating conditions. Due to the inertness of alumina, the high-temperature alumina carrier will not become a potential source of activity that causes side reactions and a decrease in sełesionatività, né ła deventarà na fonte potensiałe de toxicità pa ła catałista sistema.
(2) Interactive carrier. This type of alumina is the most widely used. It can react with the active components of the catalyst, disperse the active components of the catalyst into the carrier, and provide the active components with effective specific surface area and suitable pore structure to improve the thermal stability of the catalyst. And anti-toxic proprietà.
(3) Na sinergica o dual fol-fun-funsion-funsion-funsion-filtrasion come el scheletro del conponente ativo, sto tipo de auna el prevede anca un efeto de guadagno par l’efeto catałitico del catałista..
