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.
预计到2030年，正丙苯的全球市场价值将达到304.7亿美元，2023年至2030年的复合年增长率为4.3%。该市场分析确定了丙苯的多种应用，涵盖石油工业、工业化学品、汽车行业等。该研究引入了丁香酚，一种从木质素衍生的化合物，作为生物油制正丙苯（生物燃料类似物）生产的模型化合物。开发了一种新型的Re-Ni/KIT-6-H-丝光沸石催化剂用于丁香酚的高效加氢脱氧，在中等温度下显示出高转化率和选择性。综合表征技术和理论计算突出了Re和Ni金属之间的协同相互作用。该催化剂的可重复使用性以及在大气条件下生物燃料生产中的成功应用进一步验证了其潜力。本研究率先探索用于木质素衍生化合物加氢脱氧的Re-Ni双金属催化剂，为可持续生物燃料开发提供了有价值的见解。
