低温甲醇液相合成高效稳定催化剂的研究

A lot of Cu-based catalysts were studied and we found that co-precipitation from sol state and complex-coprecipitation were two better methods to prepare the catalysts. Two typical catalysts were made, which had high activity and high selectivity in the reaction of methanol synthesis at low temperature. The preparation method and the low temperature process of methanol synthesis were optimized and the invention patents were applied. The deactivation mechanism of the catalyst was also studied. The results have formed a solid base for the further industrialazation. According to these, two invention patents were approved and seven papers were published in national and international journals.
