天然矿研制催化剂活性载体

Research on Preparation of Activacted Bauxite for Catalyst Supporter from Aluminite

利用ＸＰＳ，ＸＲＤ，ＴＡＳ，ＢＥＴ等表征手段对某铝土矿进行剖析研究．确定一种转型变相加工工艺，使矿中的水合铝转变为活性相，其比表面达到１２８ｍ２／ｇ，孔容量为０．２２ｃｍ３／ｇ，吸水性为３８．５％，强度＞８０Ｎ／粒，可直接用作某些催化剂的载体．

The characterization of a bauxite has been analysed and we obtain a technologicalprocess of the aluminite converted to activated bauxite,with a specific surface area of 130m￣2/g,a aperture volume of 0.22 cm￣3/g,a water absorption of 38.5%,and a machinestrength of>80 N/grain. The activated bauxite can be applied to be a catalyst supporter directly.
