| 摘要: |
one layer of neutral Silicalite-1 zeolite shell was first synthesized on the bimetallic Cr/ZnO core catalyst,
acting as the intermediate layer for the following H-type H-ZSM-5 zeolite shell direct synthesis on its
surface. By using this dual-layer method, it can be easily realized that the formation of H-ZSM-5 zeolite
membrane on the millimeter-sized bimetallic substrates. Direct synthesis of dimethyl ether (DME) from
syngas at higher reaction temperature was the application of this zeolite capsule catalyst to test its catalytic
performance. In reaction, this zeolite capsule catalyst could realize the exactly controlled synthesis
of DME, suppressing the formation of other alkane/alkene by-products simultaneously, demonstrating
its exclusive ability for the selective synthesis of target product compared with the conventional hybrid
catalyst. |
