The composition of the different fractions constituting a distillation plant for neutral ethanol production was analysed. Not only the fractions that are usually discarded from the plant (heads and fusel oils) were studied but also the ones that usually circulate within the plant, passing from one column to another, which are normally impossible to reach. It was thus possible to follow the path of each component inside the plant in order to observe where it accumulates and where is disposed of. The potential exploitation of these by-products and of the chemicals involved in the processing of neutral ethanol were taken into consideration and new approaches for their use, such as in fuel cell technology, were proposed.

分析构成用于中性乙醇生产的蒸馏设备的不同馏分的组成。不仅如此，通常从植物（丢弃级分头和燃料油）进行了研究，但也是那些通常在工厂内循环，从一列传递到另一个，这通常是不可能达到。因此，可以沿着工厂内部每个组件的路径进行操作，以观察组件在何处堆积和在哪里处置。考虑了对这些副产物和中性乙醇加工中涉及的化学物质的潜在开采，并提出了将其用于燃料电池技术等新方法的使用。
