我们对电解反应堆进行了改造和表征,以完善区域和社区规模的废弃物向燃料或化学品的转化过程。整个过程必须能够适应各种原料,具有内在的安全性,并且不应依赖外部设施获得共反应物或增加排热量和供热量。我们目前的方法是基于对含碳废弃物的水热液化(HTL)生产的生物油进行升级。HTL可以将各种原料转化为生物油,与其他解构生物质的方式相比,它需要的升级要少得多。我们目前正在研究电化学过程的使用,以进一步将HTL产生的生物油转化为燃料或价值更高的化学品。我们和其他一些研究者已经证明,电化学还原可以提供足够的反应速率,至少在很小的程度上提供了一些必要的通用性。此外,电化学反应器必须在反应器的一侧氧化(去除电子)并在另一侧还原(添加电子)。因此,原则上,这两种类型的反应可以结合以提升生物油的性能,并改善在上游HTL中用作反应物和载体的水质。在这里,我们对假定流程、可能的转化化学和HTL电化学过程的经济性进行了概述。
