利用TPS（Temperature－programmed－sulfiding）方法考察了WO_3在γ－Al_1O_3TiO_2－Al_2O_3及活性碳上的硫化过程．结果发现，随着WO_3担载量的增加，表面W物种硫化峰的数目增加，表明WO_3的担载量超过一定量后，在这三种担体表面，都有几种W物种同时存在；WO_3／TiO_2－Al_2O_3与WO_3／Al_2O_3相比，当WO_3担载量低于一个单层分布时，硫化温度明显降低，而超过一个单层分布后，两者的硫化温度相接近，表明TiO_2的调变作用对低于一个单层分布的WO_3的硫化行为有较大的影响．以活性碳作为担体可明显降低W物种的硫化温度，并且活性碳在程序升温过程中，当温度超过700K后出现了气化现象．文中还就WO_3在TiO_2－Al_2O_3担体表面的结构模型提出了设想．
The temperature-programmed-sulfiding (TPS) method was used to investigate the vulcanization of WO 3 on γ-Al 1 O 3 TiO 2 -Al 2 O 3 and activated carbon. The results showed that with the increase of the WO3 loading, the number of sulfide peaks on surface W species increased, indicating that W3 species coexisted on the surface of these three kinds of supports when the loading of WO3 exceeded a certain amount. WO3 / Compared with WO_3 / Al_2O_3, the temperature of vulcanization obviously decreases when the loading of WO_3 is lower than that of WO_3 / Al_2O_3, while the temperature of vulcanization of both TiO_2-Al_2O_3 and WO_3 / Al_2O_3 is obviously lower than that of WO_3 / Al_2O_3. For less than a single distribution of WO_3 vulcanization behavior has a greater impact. With activated carbon as a carrier can significantly reduce the W species vulcanization temperature, and activated carbon in the process of warming, when the temperature exceeds 700K after the gasification phenomenon. The paper also proposed the structure model of WO_3 on the surface of TiO_2-Al_2O_3 support.
