摘要:采用水蒸汽气化木屑制备生物质气,在下游的重整反应器内,通过两段催化重整焦油,焦油裂解率高得96.70%。在双功能催化剂JC207/HZSM-5催化剂上,对生物质气合成二甲醚进行了实验研究。利用原生物质气以及脱碳生物质气考察了不同温度、压力和空速对合成二甲醚的影响。结果表明,在260℃,4 MPa、2400 L/(kgcat·h)条件下,原生物质气的CO单程转化率达到67.95%,单位质量催化剂的最大二甲醚时空收率0.338g/(gcat·h)。脱碳生物质气的CO单程转化率达到75.52%,单位质量催化剂的最大二甲醚时空收率0.583g/(gcat·h)。
A bifunctional catalyst JC207/HZSM-5 was used for dimethyl ether(DME)synthesis from a synthetic gas, which was produced by pine sawdust steam gasification combined with two sections of catalytic cracking. The tar cracking rate is up to 96.70%. Effect of temperature, pressure and space speed on synthesizing DME was studied by CO2-rich biogas and decarbonization biogas. The results showed that about 67.95% CO conversion and 0. 338g/(gcat· h) DME yield could be achieved under the condition of 260℃, 4MPa, 2400L/(kgcat·h), CO2-rich biogas. About 75.52% CO conversion and 0. 583g/(gcat· h) DME yield could be achieved under the same conditions, decarbonization biogas.
