Biomass feedstocks offer very promising sustainable production of fuels and chemicals as fossil fuels generate greenhouse gases and are going to become scarce. Nevertheless, establishing value addition to biomass waste to produce commodity chemicals by combining economic and environmental performances is complex. In this context, hydrogenation of biomass based levulinic acid at normal atmospheric reaction conditions using robust cobalt supported on porous heterogeneous catalyst has been studied at 200 °C in a continuous process. The systematic investigation of Lewis acidic sites and low reaction temperature contribute to achieve 99% conversion of levulinic acid and 80% selectivity of γ-velerolactone.

生物质原料提供了非常有希望的可持续燃料和化学产品生产，因为化石燃料会产生温室气体，并且将变得稀缺。然而，通过结合经济和环境绩效来建立生物质废物的附加值以生产商品化学品是复杂的。在这种情况下，已经在200℃连续过程中研究了使用负载在多孔非均相催化剂上的坚固钴在正常大气反应条件下氢化基于生物质的乙酰丙酸。对路易斯酸性位点和低反应温度的系统研究有助于实现99％的乙酰丙酸转化率和80％的γ-velerolactone选择性。
