Oxidation of ethylene to ethylene oxide
2026-08-18
| Section | Description |
| Project Description | Petrochemical project for producing ethylene oxide by direct oxidation of ethylene. |
| Industry | Petrochemicals |
| Technological process | Direct oxidation of ethylene to ethylene oxide. |
| Challenges | Increasing ethylene conversion and selectivity for ethylene oxide while reducing energy costs. Ensuring long-term stable operation of the catalyst under conditions of high temperatures and pressure. Minimize the formation of by-products. |
| Technical solution | Supply of 500 tons/year of silver catalyst based on advanced silver-on-carrier technology with precision control of metal particle dispersion. The catalyst was developed as part of a joint program with the Lanzhou Petrochemical Research Center (PetroChina) and the Beijing University of Chemical Technology at the Joint Laboratory of Molecular Catalysis and Engineering. This made it possible to solve the problems of design and synthesis of a catalyst for ethylene epoxidation. |
| Operation results | High selectivity for ethylene oxide, significantly superior to traditional catalysts. Stable operation with a lower rate of decline in activity. Significant reduction in by-product yield, facilitating subsequent separation and purification. |
| Technical features | Highly dispersed active silver, providing a large number of catalytic centers. Optimized porous carrier structure for accelerated transport of reagents and products. Excellent thermal stability and resistance to catalytic poisoning. |
