A microwave assisted low temperature decomposition process has been developed for production of high quality fuels from biomass. 180 degrees C was identified as key in the process mechanism, as the amorphous region of cellulose softens allowing a microwave induced rearrangement. Proton transfer is then possible under the microwave field resulting in acid catalysed decomposition. This low temperature process has been shown to be suitable for scale-up, producing a high quality char for use as a coal replacement and bio-oil suitable for upgrading to liquid fuel.
一种微波辅助低温分解工艺已被开发用于从生物质生产高质量燃料。180°C 被确定为该工艺机制中的关键，因为纤维素的无定形区域软化，允许微波诱导重排。然后，质子转移在微波场下成为可能，导致酸催化分解。事实证明，该低温工艺适合放大，可生产出高质量的炭，用作煤炭替代品，以及适合升级为液体燃料的生物油。
