Key Points

This research aims to investigate the synthesis and catalytic efficiency of C-ZSM-5 zeolites for 1-butene cracking.
Synthesis of C-ZSM-5 zeolites with different cross-linked silicon species.
Characterization of zeolites to assess hydrophobicity and acid strength.
Evaluation of catalytic performance in propylene production during 1-butene cracking.
C-ZSM-5 zeolites showed higher propylene selectivity compared to traditional zeolites.
Enhanced hydrophobicity and increased surface Al content were observed.
Demonstrated a higher P/E ratio and reduced by-products during catalytic performance.

Implication

Synthesis and characterization of C-ZSM-5 zeolites improved propylene selectivity, indicating potential for enhanced catalytic applications.

Abstract

C-ZSM-5 zeolites, featuring enhanced hydrophobicity, higher surface Al content, relatively weak acid strength, and Al concentrated in straight/sinusoidal channels, offer superior propylene selectivity, a higher P/E ratio, and fewer by-products.
