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.

生物炼制厂的灵活性：通过氢分压调节木质素加氢

本研究描述了一种有趣且实用的催化系统，该系统可根据氢分压将木质素灵活转化为芳族或脂族烃。实验和理论的结合表明，可以通过控制催化剂表面氢的存在来简单地调节芳族化合物和脂肪族化合物之间的产物分布。值得注意的是，这些途径导致木质素生物质中的氧气几乎完全去除，从而产生高质量的碳氢化合物。因此，通过使用这种催化系统进行氢-木质素共精制，可以满足不同的区域和时间需求，在储氢/消耗氢方面具有很高的灵活性。
