Tuning Ruthenium States for Enhanced Polyethylene Hydroconversion over HZSM-5 Catalysts

Key Points

• The research aims to explore how tuning ruthenium chemical states affects product selectivity during polyethylene hydroconversion.
• Investigated the effects of Ru chemical states on polyethylene hydroconversion.
• Analyzed the Ruδ+/Ru0 ratio in relation to product selectivity.
• Focused on Ru/HZSM-5 catalyst performance during hydroconversion.
• Found that the Ruδ+/Ru0 ratio predominantly influences product selectivity.
• Determined that an optimal Ruδ+/Ru0 ratio of 4.54 results in 71.5% liquid product yield.
• Noted that particle size is less significant compared to the ratio of ruthenium states.
