Synthesis of Nano‐Hierarchical Ferrierite with Sole Template and Its Catalytic Application in n‐Butene Skeletal Isomerization

Abstract

Nano-hierarchical ferrierite(FER) was successfully synthesized by using pyrrolidine as sole organic structure directing(OSDA) agent under static hydrothermal conditions.SEM images showed that the morphology of the product was a loose threestage accumulation structure by nano-rod crystal grains .The influence of crystallization temperature, gel alkalinity, crystal-lization time and the amount of OSDA on synthesis of FER was investigated in detail.Moreover,FER catalytic performance in nbutene skeletal isomerizatio was investigated.The results showed that, compared with the commercial FER, the nanohierarchical FER showed better catalytic activity.

State of the Art and Perspectives of Hierarchical Zeolites: Practical Overview of Synthesis Methods and Use in Catalysis

“…Both research groups tested the nanoferrierite aggregates in the skeletal isomerization of n-butene and found improvements of selectivity and stability. [55,56] Margarit et al used two SDAs (piperidine (Pip) and cetylmethylpiperidinium bromide (C 16 MPip)) to synthesize nanoferrierite crystals. The first SDA initiates the crystallization process, while the second SDA restricts crystal growth.…”
