Dataset for “Hierarchical ZSM-5 with Encapsulated Co-La Sites for Light Aromatics Production and Coke Suppression in Lignite Pyrolysis”

The dataset includes data related to catalyst preparation and characterization, lignite catalytic pyrolysis performance, product distribution, light aromatic formation, catalyst regeneration stability, and coke deposition behavior.

Characterization data include XRD, nitrogen adsorption–desorption, SEM, TEM/HRTEM, XPS, NH3-TPD, FTIR/CO-FTIR, TGA/DTG, and TPO results. The dataset also contains catalytic pyrolysis data obtained using ZSM-5, FZ5, CoLa/FZ5, and CoLa@FZ5 catalysts, including gas and liquid product distributions, GC-MS-derived tar composition, BTEXN relative abundance, kinetic parameters, and regeneration-cycle performance. These data support the analysis of the effects of hierarchical pore structures and encapsulated Co-La bimetallic sites on light aromatic production and coke suppression during lignite pyrolysis.
