The new SMTO catalyst developed by Sinopec Shanghai Research Institute has passed the evaluation by the group company

Thread Content

Recently, the group company project “Industrial testing of new SMTO catalysts”, undertaken by the Sinopec Shanghai Research Institute of Petrochemical Technology (referred to as Shanghai Institute), passed the appraisal. With the support of the **Key R&D Program and Sinopec’s major projects, this project achieved the successful development of a new SMTO-2 catalyst through the innovation of crystallization-guiding templates. Compared to the SMTO-1 catalyst, it exhibits significantly improved crystallinity, effective active center density, and catalytic performance. The project also developed new processes for the crystallization of molecular sieves and the preparation of catalysts, which significantly reduced the crystallization time required for molecular sieves and greatly diminished the amount of wastewater and waste solids generated. The SMTO-2 catalyst has been put into industrial use in S-MTO plants such as Zhongyuan Petrochemical and Zhongan United. With the use of this catalyst, the selectivity for dienes increases significantly, the methanol consumption decreases, and the economic efficiency of the plants improves markedly. This project applied for 17 Chinese patents, of which 9 were granted; the research results are innovative and possess independent intellectual property rights. The expert group believes that the new SMTO catalyst developed for this project features high diene selectivity and low methanol consumption, and its technical parameters are generally superior to those of similar catalysts reported domestically and internationally.
