| 摘 要： | 研究了共沉淀法制备的系列金属负载型催化剂合成气制甲醇反应性能，重点考察了催化剂上合成甲醇反应体系的耐硫性能。结果表明，Cu/ZnO催化剂显示了较好的甲醇合成反应性能，但该反应在含硫气氛下迅速失活；Pd/CeO2催化剂体现了良好的甲醇合成反应性能和该反应体系的高耐硫性能。结合多种物理化学表征手段分析得出, Cu/ZnO催化剂在含硫气氛下因活性组分形成金属硫化物而失活；Pd/CeO2催化剂中的载体CeO2可优先与硫作用而保护金属活性组分，进而保持了Pd/CeO2反应体系的高抗硫性能。

| Abstract: | Supported metal catalysts for methanol synthesis from syngas was prepared by co-precipitation method and its sulfur resistance was studied.The experimental results show that Cu/ZnO exhibited the best methanol synthesis activity but deactivated quickly when sulfur-contaminated syngas was used.However,Pd/CeO2 showed stable methanol synthesis activity in the sulfur-contaminated syngas.The characterization results indicate that the active components of Cu/ZnO reacted with H2S in syngas and deactivated the metha... |
