The UK is committed to stringent carbon budget commitments requiring complete decarbonisation of the energy system by 2050. It is generally expected that low carbon liquid fuels will form a key component of the UK's mid-term decarbonisation efforts (2025-2040) and that in the long term (2040-2050) deployment of bioenergy with carbon capture and storage will be required to meet UK and global net negative carbon commitments. Development of low-carbon liquid fuels is therefore essential for the UK future low carbon energy system.Biomass is the only sustainable feedstock to produce renewable organic chemicals. One of the most interesting chemicals that can be produced from lignocellulosic biomass is Y-valerolactone (GVL). GVL can be blended with gasoline up to 10% and is a precursor to liquid alkanes in the diesel and jet fuel range, as well as some useful chemicals with applications as eco-friendly solvents and in polymers production.Currently the process of GVL production from biomass-derived feedstocks is based on a cascade process, starting with the fractionation of lignocellulosic biomass and sugar productions. Subsequently, the sugars will undergo acid catalysed transformation to levulinic acid, followed by noble-metal catalysed hydrogenation of levulinic acid to GVL using H2 gas. However, this approach comes with some significant drawbacks such as the application of expensive metal catalysts (e.g. Ru or Pt) for the levulinic acid hydrogenation step and also high pressure H2 (greater than 30 bar) which can have a huge negative impact on the process safety, sustainability and economics.Alternatively, hydrogenation can be performed using liquid hydrogen donors such as renewable alcohols. This so-called "catalytic transfer hydrogenation" (CTH) process can be catalysed by inexpensive metals (e.g. Zr or Ni), allowing hydrogen transfer from the H-donor to the target molecules.Through experimental methodologies, this project will develop a new energy-efficient and cost-effective catalytic process for GVL production from bio-based feedstocks by utilising alcohols as hydrogen source. New and commercially relevant solid catalysts will be developed through a rigorous bottom-up approach to catalyst design, synthesis, characterisation, and testing

英国致力于在2050年到2050年的能源系统进行严格的碳预算承诺。通常预计低碳液体燃料将构成英国中期脱碳工作的关键组成部分（2025-2040）（2025-2040），并且在长期（2040-2050）中（2040-2050）将使用碳和储存的碳库捕获碳和存储量会遇到碳的销售。因此，低碳液体燃料的开发对于英国未来的低碳能体系至关重要。生物量是唯一生产可再生有机化学物质的可持续原料。可以用木质纤维素生物量产生的最有趣的化学物质之一是Y-谷周期（GVL）。 GVL可以与高达10％的汽油混合，并且是柴油和喷气燃料范围中液态烷烃的先驱，以及一些有用的化学物质，其应用为环保溶剂和聚合物的生产。当前，GVL生产的过程是基于生物量的原料从cascade Conderation和sugionation conteration confortation和frictation frationation frationation frationation frationation frationation frationals frational frolcaltion。随后，糖将经过酸将酸的转化为葡萄糖酸，然后使用H2气体将葡萄糖酸的贵重金属催化液化为GVL。但是，这种方法具有一些重要的缺点，例如在葡萄蛋白酸氢化步骤中应用昂贵的金属催化剂（例如RU或PT），以及高压H2（大于30 bar），这可能会对过程安全性，可持续性和经济性产生巨大的负面影响，并且可以使用液体供体的液体供体进行氢化，例如使用液体供体进行液体供体，例如使用液体供体腐蚀性。 This so-called "catalytic transfer hydrogenation" (CTH) process can be catalysed by inexpensive metals (e.g. Zr or Ni), allowing hydrogen transfer from the H-donor to the target molecules.Through experimental methodologies, this project will develop a new energy-efficient and cost-effective catalytic process for GVL production from bio-based feedstocks by utilising alcohols as hydrogen source.将通过严格的自下而上的催化剂设计，合成，表征和测试来开发新的和商业上相关的固体催化剂
