伽馬氧化鋁修改四.jpg

氧化鋁載體形態(tài)為白色固體,有球狀和粉狀兩種常用形狀,無(wú)毒、無(wú)臭、不粉化、不溶于水和乙醇。焙燒溫度大體在500-800℃之間,根據孔容大小之分可以做成中孔,大孔等載體,做成的載體具有活性強,孔容大,吸水率高等特點(diǎn)。根據催化劑用途在載體中加入適當的活性助劑(如:MO-Al、Ni- Al、Mn- Al、Ti- Al、CO- Al、K- Al等)制成不同用途的催化劑,用于石油化工,水處理,環(huán)保行業(yè),固定床和移動(dòng)床環(huán)境都可以有不同使用。球狀載體也可以根據客戶(hù)要求在載體中加入適量氧化硅,氧化鐵,氧化銅,氧化鈦等直接制成催化劑使用。常用包裝有:25公斤/袋,25公斤/桶,100公斤/桶

球狀氧化鋁載體基本參數有:AL2O3≥92%,比表面積≥150m2/g,堆積密度≥0.45g/mL,孔容≥0.45ml/g,吸水率≥70%等。

The alumina carrier is a white solid with two common shapes, spherical and powdery, non-toxic, odorless, non-powdery, insoluble in water and ethanol. The calcination temperature is about 500-800 ℃. According to the size of pore volume, mesoporous and macroporous carriers can be made. The carrier made has strong activity, large pore volume and high water absorption. According to the purpose of the catalyst, add appropriate active additives (such as MO-Al, Ni-Al, Mn-Al, Ti-Al, CO-Al, K-Al, etc.) into the carrier to make catalysts for different purposes, which can be used in petrochemical, water treatment, environmental protection industries, fixed bed and mobile bed environments. 

Spherical support can also be directly used as catalyst by adding appropriate amount of silicon oxide, iron oxide, copper oxide, titanium oxide, etc. into the support according to customer requirements. 

Common packaging: 25kg/bag, 25kg/barrel, 100kg/barrel.
