用生物质能替代石油在经济上是可行的，因为它能从三种主要的生物质能成分中产生收入。可再生化学品和生物燃料的生产必须在成本和性能上与石油衍生产品具有竞争力，才能被市场和社会广泛接受。我们提出了一种生物质转化策略，最大限度地将木质纤维素生物质（高达80%的生物质转化为有用的产品）转化为可商业化的高价值产品，为成功转化为经济上可行的商业过程提供机会。我们的分馏方法保留了所有三种主要成分的价值：(i)纤维素，它被转化为可溶解的纸浆，用于纤维和化学品生产；（ii）半纤维素，可转化为糠醛（一种基本化学物质）；（三）木质素，它被转化为碳产品（碳泡沫、纤维或电池阳极），每干吨生物质的收入超过500美元。一旦去风险，我们的技术可以扩展到生产其他可再生化学品和生物燃料。
Replacing petroleum by biomass can be economically feasible by generating revenue from the three primary biomass constituents. The production of renewable chemicals and biofuels must be cost- and performance- competitive with petroleum-derived equivalents to be widely accepted by markets and society. We propose a biomass conversion strategy that maximizes the conversion of lignocellulosic biomass (up to 80% of the biomass to useful products) into high-value products that can be commercialized, providing the opportunity for successful translation to an economically viable commercial process. Our fractionation method preserves the value of all three primary components: (i) cellulose, which is converted into dissolving pulp for fibers and chemicals production; (ii) hemicellulose, which is converted into furfural (a building block chemical); and (iii) lignin, which is converted into carbon products (carbon foam, fibers, or battery anodes), together producing revenues of more than $500 per dry metric ton of biomass. Once de-risked, our technology can be extended to produce other renewable chemicals and biofuels.
