IntroductionThe epoxidation of olefins to form epoxides is an important industrial process used for the production of a variety of chemicals. Conventionally, the process has been carried out using organic peracids or metal catalysts, which suffer from various limitations such as high cost, low selectivity, and environmental concerns. TS-1, a zeolite-based catalyst, has emerged as a promising alternative due to its high selectivity, activity, and stability in the gas-phase epoxidation of olefins.2. ObjectivesThe objective of this study is to investigate the catalytic performance of TS-1 in the gas-phase epoxidation of ethylene and butene. The main focus of the study will be on the effect of operating parameters such as temperature, pressure, and reactant concentration on the catalytic reaction.3. Experimental procedureThe gas-phase epoxidation reaction will be carried out in a fixed-bed reactor packed with TS-1 catalyst. The reactants (ethylene and butene) will be fed into the reactor along with the oxidant (oxygen) and a solvent (acetonitrile). The reaction will be carried out under various operating conditions, including different temperatures, pressures, and reactant concentrations. The products of the reaction will be analyzed by gas chromatography-mass spectrometry (GC-MS) to determine the selectivity and yield of the epoxide products.4. Expected resultsIt is expected that TS-1 will exhibit high selectivity towards the epoxidation of both ethylene and butene, with high yields of the corresponding epoxides, ethylene oxide and butene oxide. It is also expected that the optimal operating conditions 精品文档---下载后可任意编辑for the reaction will be determined, which will include specific temperature, pressure, and reactant concentration ranges.5. SignificanceThe gas-phase epoxidation of ethylene and butene using TS-1 catalyst has the potential to be a more environmentally friendly and cost-effective method for the production of epoxides. The optimized operating conditions for the process can be used to design more efficient commercial processes, which could have significant economic implications. The results of this study will contribute to the development of more sustainable industrial processes.
