    摘要:

    論文對介質阻擋低溫等離子體法輔助制備催化劑的方法進行了研究。利用X射線衍射分析,熱重分析,掃描電子顯微鏡等方式對催化劑進行分析,實驗表明等離子體法和傳統(tǒng)焙燒處理制備的催化劑性能相近,并且利用介質阻擋低溫等離子體方式處理的催化劑在預處理速度,催化劑微觀顆粒尺寸小,分散度好等方面均優(yōu)于傳統(tǒng)焙燒的處理方式。預處理后的催化劑表面活性更有利于合成氣制備液體烴類燃料。

    Abstract:

    A catalyst preparation method using dielectric barrier discharge (DBD) plasma was investigated in this paper. The results indicated that DBD plasma is good method to prepare Mo/Co/K/ZSM-5 catalysts in a rapid and efficient way. The DBD plasma method has similar performance with the traditional roasting method using X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscope (SEM), however, the former could obtained smaller size of particles and low agglomeration degrees. The activity tests also showed that the catalysts prepared by DBD plasma have higher activities towards synthesis of hydrocarbon (C5+) directly from synthesis gas than those obtained by the traditional roasting method.
