意义 Significance
——甲醇制烯烃技术是实现石油替代战略的重要技术途径。 Methanol to olefin technology, including MTO and MTP, becomes an important intermediate linking petrochemicals to coal or natural gas chemical industry. ——开发甲醇制烯烃(MTO)技术有利于缓解石油供求矛盾。 MTO process could release the lack of petroleum and diversify the raw materials of the production of light olefins.
