The present study describes an interesting and practical catalytic system that allows flexible conversion of lignin into aromatic or aliphatic hydrocarbons, depending on the hydrogen partial pressure. A combination of experiment and theory shows that the product distribution between aromatics and aliphatics can be simply tuned by controlling the availability of hydrogen on the catalyst surface. Noticeably, these pathways lead to almost complete oxygen removal from lignin biomass, yielding high-quality hydrocarbons. Thus, hydrogen-lignin co-refining by using this catalytic system provides high flexibility in hydrogen storage/consumption towards meeting different regional and temporal demands.
本研究描述了一种有趣且实用的催化体系，可根据氢气分压灵活地将木质素转化为芳烃或脂肪烃。实验和理论的结合表明，通过控制催化剂表面上氢气的可用性，可以简单地调节芳烃和脂肪烃之间的产物分布。值得注意的是，这些途径几乎可以将木质素生物质中的氧完全去除，从而生成高质量的烃类。因此，使用该催化体系进行氢气-木质素共精炼，可以在氢气储存/消耗方面提供高度的灵活性，以满足不同地区和时间的需求。
