In this report, we introduce a novel and commercially viable method to recover renewable hydrogen and carbon nanotubes from waste glycerol produced in the biodiesel process. Gas-phase catalytic reforming converts glycerol to clean hydrogen fuel and by replacing the problematical coke formed on the catalyst with high value carbon nanotubes, added value can be realised. Additional benefits of around 2.8 kg CNTs from the reforming of 1 tonne of glycerol and the production of 500 Nm(3) H2 could have a considerable impact on the economics of glycerol utilization. Thereby, the contribution of this research will be a significant step forward in solving a current major technical and economic challenge faced by the biofuels industry.
在本报告中，我们介绍了一种新颖且可行的商业方法，可从生物柴油工艺中产生的废甘油中回收可再生氢气和碳纳米管。气相催化重整将甘油转化为清洁的氢气燃料，并且通过用高价值的碳纳米管代替催化剂上形成的有问题的焦炭，可以实现附加值。从 1 吨甘油重整和生产 500 立方米氢气中可以获得约 2.8 公斤 CNT，这将对甘油利用的经济性产生重大影响。因此，这项研究的贡献将是解决生物燃料行业当前面临的重大技术和经济挑战的重要一步。
