Research Project on Efficient Methanol-to-Propylene Conversion Approved – Author/Source: China Chemical Industry News, Date: 10-29-2018, Clicks: 13. On October 25, news came from the Science and Technology Department of the Ningxia Hui Autonomous Region that the **international scientific and technological cooperation project titled “Collaborative Research on Efficient Methanol Conversion to Propylene,” carried out by Shenhua Ningmei Group in collaboration with institutions such as the University of Ilmenau in Germany, Zhejiang University, and Ningxia University, has passed the approval process conducted by the Ministry of Science and Technology. It is reported that this project builds on the two 500,000 tons per year methanol-to-propylene plants already in operation at Shenhua Ningmei. Research was conducted on various aspects of the coal-based methanol-to-propylene process, including energy-saving techniques at different levels, as well as the patterns of catalyst deactivation due to carbon deposition over multiple reaction cycles; these findings were then put into industrial application. As a result, the average yield of propylene increased by 0.67%, the service life of the catalysts was extended by 15%, and the energy consumption per ton of product was reduced to 35.95 gigajoules. The related technologies have reached international advanced levels, providing strong technical support for the upgrading and application of large-scale methanol-to-propylene technology in China, as well as for energy conservation and consumption reduction in large-scale coal chemical projects.
Can it be understood that, based on Luchi’s \"triple MTP process,\" technical improvements were made in aspects such as (1) the entire process flow, (2) multi-level energy-saving technologies, and (3) the pattern of deactivation due to carbon deposition over multiple reaction cycles; as a result, the average yield of propylene increased by 0.67%, the catalyst’s service life was extended by 15%, and the energy consumption per ton of product was reduced to 35.95 GJ.
