Efficient methodologies for converting biomass solids to liquid fuels have the potential to reduce dependence on imported petroleum while easing the atmospheric carbon dioxide burden. Here, we report quantitative catalytic conversions of wood and cellulosic solids to liquid and gaseous products in a single stage reactor operating at 300-320 °C and 160-220 bar. Little or no char is formed during this process. The reaction medium is supercritical methanol (sc-MeOH) and the catalyst, a copper-doped porous metal oxide, is composed of earth-abundant materials. The major liquid product is a mixture of C(2)-C(6) aliphatic alcohols and methylated derivatives thereof that are, in principle, suitable for applications as liquid fuels.
高效的生物质固体转化为液体燃料的方法有可能减少对进口石油的依赖,同时减轻大气中二氧化碳的负担。在这里,我们报告了在 300-320°C 和 160-220 巴的单级反应器中,定量催化转化木材和纤维素固体为液体和气体产物。在这个过程中几乎没有或没有形成炭。反应介质是超临界甲醇(sc-MeOH),催化剂是一种铜掺杂的多孔金属氧化物,由丰富的材料组成。主要的液体产物是 C(2)-C(6)脂肪族醇及其甲基化衍生物的混合物,原则上适用于作为液体燃料的应用。
