Sustainable Aviation Fuel (SAF) is set to become a crucial product to decarbonize the aviation industry. Achieving proprietary technology leadership in this sector will help bp achieve aim 2, 3, and 5 of the sustainability goals. One emerging technology to produce SAF is through electrochemical upgrading of pyrolysis oil, a liquid produced through biomass pyrolysis. Pyrolysis oil is acidic, contains higher water-content than traditional refinery crude feed, and rich in oxygen; all of which hampers storage stability and subsequent processing (often through catalytic upgrading) in a refinery towards finished fuel products. Electrochemical hydrogenation (ECH) may offer a pre-treatment option to stabilise the oil by removing oxygen at ambient pressure and a lower temperature compared to refinery processes, hence offering potential energy and cost savings . ECH pre-treatment could thus become an important enabler for improving the trading and storage of biomass pyrolysis oil in a worldwide market, plus it could reduce the subsequent upgrading requirements to process the oil intermediate into SAF-grade end product, paving the path for a scalable SAF feedstock from biomass. The aim of the proposed PhD project is to gain a fundamental catalytic understanding of electrochemical hydrogenation of pyrolysis oil. The project will aim to answer the following questions: What are the most valuable targets for ECH pre-treatment from pyrolysis oil?What is the underpinning mechanism/surface chemistry to perform ECH for pyrolysis oils leading to the preferred products? Can we engineer a catalyst that is selective to ECH and active for all preferred components? How do we assess the true catalyst performance and deactivation mechanisms with non-model compounds?

可持续航空燃料（SAF）将成为航空业脱碳的关键产品。在该领域实现专有技术领先地位将有助于 bp 实现可持续发展目标中的目标 2、3 和 5。生产 SAF 的一项新兴技术是通过热解油的电化学升级，热解油是一种通过生物质热解产生的液体。热解油呈酸性，含水量高于传统炼厂原油原料，且富含氧气；所有这些都会妨碍炼油厂成品燃料产品的储存稳定性和后续加工（通常通过催化升级）。电化学加氢 (ECH) 可以提供一种预处理选项，通过在环境压力和比炼油工艺更低的温度下去除氧气来稳定油品，从而提供潜在的能源和成本节约。因此，ECH 预处理可能成为改善全球市场生物质热解油交易和储存的重要推动因素，此外，它还可以减少将油中间体加工成 SAF 级最终产品的后续升级要求，为从生物质中生产可扩展的 SAF 原料铺平道路。拟议的博士项目的目的是获得对热解油电化学加氢的基本催化理解。该项目旨在回答以下问题：对热解油进行 ECH 预处理最有价值的目标是什么？对热解油进行 ECH 产生首选产品的基础机制/表面化学是什么？我们能否设计出一种对 ECH 具有选择性并对所有首选组分都具有活性的催化剂？我们如何评估非模型化合物的真实催化剂性能和失活机制？
