Alumine oyo esalelamaka lokola porteur ya catalyseur ekoki kozala na bokuse na ba types oyo elandi selon ba propriétés physiques mpe chimiques na yango mpe rôle oyo Alumine a jouaka :
(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 selectivity, nor will it become a potential source of toxicity for the catalyst system.
(2) Porteur interactif. Lolenge oyo ya alumine ezali oyo esalelamaka mingi. ekoki kosala na ba composants actifs ya catalyseur, kopalanganisa ba composants actifs ya catalyseur na kati ya porteur, mpe kopesa ba composants actifs na surface spécifique ya surface spécifique mpe structure ya ba pores oyo ebongi mpo na kobongisa stabilité thermique ya catalyseur. mpe ba propriétés antipoxes{5}}
(3) Porteur synergique to dual-fonction. En plus ya kosala lokola skeleton ya composante actif, lolenge oyo ya alumine epesaka mpe effet ya gain mpo na effet catalytique ya catalyseur.
