In the past few years, MTBE production technology has shown a trend of diversification of raw materials, expansion of a single set of equipment, and increased output rate. based on the traditional ether pre-carbon four production process, the post-ether C4 isomerization process, isobutane dehydrogenation process and PO/MTBE co-oxidation process have been developed, which effectively alleviated the problem of insufficient supply of MTBE raw materials and improved MTBE Capacity. In 2018, my country's MTBE devices from Shandong Kenli Petrochemical, Ningxia Baoli Chemical, Ningxia Ruike Xinyuan, and PetroChina Daqing Petrochemical have been put into production one after another, and MTBE production capacity has maintained a rapid growth rate.
