| 摘 要： | 在双功能催化剂JC207/HZSM-5上,对流化床内制备的生物质气脱碳后合成二甲醚进行了研究。结果表明,二甲醚时空产率在260℃达到最大;随反应压力升高而增大;随空速的增加,时空产率先增加后降低。同时发现,在合成二甲醚的生物质气中须把生物质气中二氧化碳降低到5%后才可以提高甲醇合成反应速率,进而提高二甲醚合成反应速率。

| Abstract: | A bifunctional catalyst JC207/HZSM-5 was used for dimethyl ether(DME)synthesis from a biomass- syngas, which was produced by pine sawdust steam gasification combined with two sections of catalytic cracking. Effects of temperature, pressure and space velocity on DME synthesis were studied by biomass-syngas. The results showed that DME yield achieved maximum at 260℃, the yield increased with the increase of reaction pressure. But the yield increased and then decreased with the increase of SV(space velocity). In addition, the rate of methanol synthesis increased if the content of carbon dioxide in the biomass syngas reduced to 5%, resulting in the increase of the formation rate of DME. |
