通过一系列的案例研究表明，微波介质加热可以从广泛的生物质类型中回收和合成有价值的分子。此外，在微波照射下，与传统加热相比，生物质化学物质的生产在明显较低的温度下进行（高达150摄氏度）。这样做的第二个好处是，产生了具有高度功能性的分子，而传统的加热往往会产生很大比例的低价值气体。此外，微波反应器的技术设置可以很容易地适应酸和有价值产品的原位分离，从而提高后者的保质期。同时也说明了水热条件与微波辐照相结合的好处。此外，还讨论了双相反应系统中选择性加热的特殊情况，以提高收率和选择性。(C) 2013 Elsevier B.V.版权所有
Through a series of case studies it is demonstrated that microwave dielectric heating can be a powerful tool to recover and synthesize valuable molecules from a wide range of biomass types. In addition, under microwave irradiation the production of chemicals from biomass proceeds at markedly lower temperatures (up to 150 degrees C) compared to conventional heating. This has a secondary benefit in that molecules with a high degree of functionality are produced while conventional heating tends to produce a great proportion of lower value gases. Furthermore, the technical set-up of a microwave reactor can easily accommodate for an in-situ separation of acids and valuable products therewith improving the shelf life of the latter. The benefits of combining hydrothermal conditions with microwave irradiation are also illustrated. In addition, a specialized case of selective heating in a biphasic reaction system is discussed, allowing for improved yields and selectivity. (C) 2013 Elsevier B.V. All rights reserved.
