摘要：

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 mu m 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.
