Abstract：To improve the domestic research level of MTP technology and propylene,the products distribution characteristics of typical MTO (Methane to Olefins) technology,naphtha cracking technology,MTP (Methane to Propylene) technology were analyzed.Using MTP technology,the main product is propylene,while mathane and N2,O2,NOx is less.C4 and C5+ is more,so the separation is easy.Introduce the products separation process of MTP.Investigate the application of MTP,developed by Lurgi,in Shenhua Ningxie Coal Industry Group and Datang Duolun Coal Chemical Industry Company.There are lots of problems with the separation system.The materials which need to be recycled are large,the separation process is long and consumes lots of energy.The MTP technology should be transformed based on its prod-ucts distribution characteristics and MTO technology,naphtha cracking technology.
