摘要
介绍了用ＣＯ作吸附质，在室温下脉冲吸附测定铜催化剂中活性铜表面积的方法。试验结果表明，在不同载气中进行ＣＯ吸附，所得吸附量略有差异，Ｈｅ载气中测得结果略高于Ｈ２载气中测得的结果。结果还表明，本方法重复性好，相对误差在５％以内，可以作为快速评选催化剂的有效方法。
A determination method of active surface areas of copper-containing catalysts by pulse adsorption at an ambient temperature with CO as adsorbate is described in the present paper.The experimental results show that the obtained adsorbances are slightly different when CO adsorption is conducted in various carrier gases. The determined data for He carrier gas is slightly higher than that for H2 carrier gas.The results also show that the method has agood reproductivity and the relative error is within 5%, which can be used as an effective method for fast evaluation and selection of catalysts.
