The characterization of FTIR demonstrates that the acetic acid species is adsorbed in the catalyst surface after reaction, especially the reaction with water.
FTIR表征表明反应后的催化剂表面有乙酸物种生成，尤其是在含水进料方式反应后的催化剂表面尤为明显。
In combination with the gravimetric method, one can obtain the adsorption amount of water and the thickness of adsorbed water layer on solid surface under various driving gradient pressures.
结合重量分析，用离心法可得到不同驱动压力梯度下的吸附水量及吸附水层厚度。
