Abstract
The global market for n-propyl benzene value is projected to reach $30.47 billion by 2030, with a CAGR of 4.3% from 2023 to 2030. This market analysis identifies diverse applications for propyl benzene, spanning the petroleum industry, industrial chemicals, automotive sector, and more. The research introduces eugenol, a compound derived from lignin, as a model compound for bio-oil to n-propyl benzene (bio-fuel analogs) production. A novel Re-Ni/KIT-6-H-Mordenite catalyst is developed for efficient hydrodeoxygenation of eugenol, showcasing high conversion rates and selectivity under moderate temperatures. Comprehensive characterization techniques and theoretical calculations highlight the synergistic interaction between Re and Ni metals. The catalyst’s reusability and successful application for bio-fuel production under atmospheric conditions further validate its potential. This study pioneers the exploration of Re-Ni bimetallic catalysts for HDO of lignin-derived compounds, offering valuable insights into sustainable bio-fuel development.
