镍催化剂在热重仪内773K还原后,用氮吹扫,降至室温,脉冲进空气,根据增重量算出金属镍的表面积。逐渐升温氧化测得还原镍量。在473K脉冲进CO也可以测得镍表面积。分别用脉冲重量O_2吸附法,脉冲重量CO吸附法,测量了几种负载镍催化剂的镍表面积,并与脉冲色谱O_2吸附法和静态容量H_2吸附法所测结果进行比较。 Nickel catalyst in the thermal gravimetric instrument 773K reduction, purged with nitrogen, cooled to room temperature, pulsed into the air, calculated according to the weight gain of nickel metal surface area. The temperature was gradually increased oxidation of nickel reduction. In 473K pulse into the CO can also measure the nickel surface area. The nickel surface area of ​​several supported nickel catalysts was measured by pulse O_2 adsorption and pulse CO adsorption methods, respectively. The results were compared with the results of O_2 adsorption and H_2 adsorption.
