摘　　要：简单介绍了二甲醚的用途及对解决能源和环境问题的重要意义。综述了国内外特别是国内三相床反应器中由合成气直接合成二甲醚的研究和开发新进展。重点介绍了影响该工艺过程工业化的关键问题———催化剂失活的原因和改进措施。Application and significance of dimethyl ether for solving the energy and environment problems are briefly introduced. Recent advances in the direct synthesis of dimethyl ether from syngas in three-phase reactors are reviewed with emphasis placed on the cases in China. The key problem affecting the industrialization of this process, catalyst deactivation, and the measures to solve this problem are discussed in detail.
