| 摘 要： | 在磁力搅拌高压釜内进行了文题的研究。考察了五种石油加工工业催化刺单独和混合使用时,对煤加氢液化的影响。发现加氢裂解催化剂和加氢精制催化剂按1:1混合使用,可获得较高的煤转化率和油产率,氢耗也较低。进一步研究表明,该混合催化剂适于在较低温度下使用,最佳液化温度随其它操作参数变化。当有催化剂存在时氢压对转化率的影响比无催化剂时显著。催化剂用量增大对液化有利,但操作成本增加。

| Abstract: | The coal hydroliquefaction is conducted in a magnetically stirred autoclave. The effects of five commercial catalysts are investigated in both separate and combined use. It is found that if the hydrocracking catalyst and the hydrorefining catalyst are used in ratio of 1:1, both high coal conversion and oil yield can be obtained, and the hydrogen consumption is low. Further studies show that relatively low temperature is favorable for this blend catalyst. The optimum liquefaction temperature varies with the variation of other reaction conditions. The influence of hydrogen pressure on liquefaction is more significant in the presence of catalyst. Large catalyst amount is beneficial to liquefaction, but it is restricted by the consideration of cost. |
