| 摘 要： | 采用干磨法,选用不同种类甲醇合成组分和不同种类的甲醇脱水组分制备双功能催化剂,并在高压固定床反应器评价其催化性能.研究表明,催化剂JC207是一种较优的甲醇合成催化剂,其最佳配比为80％.分子筛是一种较好的甲醇脱水催化剂,其最佳配比为20％.通过寿命试验和催化剂的XRD表征发现催化剂晶相没有改变,催化剂结构保持稳定.

| Abstract: | Bi-functional catalysts were prepared by dry grinding of different components of catalysts for methanol synthesis and methanol dehydration.Their catalytic activity were evaluated with a high-pressure fixed-bed reactor.Results indicated that JC207 was a good catalyst for synthesis of methanol.Its optimum ratio was 20%in bi-functional catalyst.Zeolite was a good catalyst for methanol dehydration.Its optimum ratio was 80%in bi-functional catalyst.Stability test and XRD analysis of bi-functional catalyst confir... |
