我们报道了一种宏观的不锈钢纤维@HZSM-5核壳催化剂，通过使用20 μm的SS纤维在3D微纤维结构上直接生长27 wt%的HZSM-5，证明了MTP过程中显着的选择性和稳定性改善。这种前所未有的性能是由于在甲醇制烃催化中促进了烯烃甲基化/裂化循环。
We report a macroscopic stainless-steel-fiber@HZSM-5 core-shell catalyst by direct growth of 27 wt% HZSM-5 on a 3D microfibrous structure using 20 μm SS fibers, demonstrating dramatic selectivity and stability improvement in the MTP process. The unprecedented performance is due to the promotion of the olefin methylation/cracking cycle in methanol-to-hydrocarbon catalysis.
