Bio-oil produced from the pyrolysis of lignocellulosic waste biomass is chemically complex, with high oxygen content, acidic properties and tendency to polymerise, the bio-oil is also immiscible with crude petroleum oil. The aim of the research is to produce a low oxygen, low viscosity bio-oil from lignocellulosic waste biomass suitable for direct processing in existing petroleum oil refineries.This project seeks to develop a novel process involving co-pyrolysis of waste biomass and waste plastics to produce a suite of gases and vapours which are then passed directly to a low temperature (< 200 C) non-thermal plasma-catalysis reactor where upgrading of the bio-oil takes place to produce a low oxygen premium grade bio-oil. The role of the waste plastics is to act as hydrogen donors in the bio-oil upgrading process. The project involves experimental work on a novel two-stage laboratory scale reactor and analysis of the product oils and gases using a range of analytical techniques. Experiments will seek to optimise the plasma-catalytic process conditions to maximise bio-oil deoxygenation with detailed analysis of the product oils and gases. In addition, a key topic of the research is the development of new catalysts that are effective in the plasma-catalytic environment. The project seeks to develop a new low energy process to produce upgraded bio-oil, thereby benefiting the growing pyrolysis bio-oils industry. Also, providing a novel route to obtain high value products from waste biomass and waste plastics.

由木质纤维素废弃生物质热解产生的生物油化学性质复杂，具有高氧含量、酸性和聚合倾向，并且生物油与原油不混溶。该研究的目的是从木质纤维素废生物质中生产出一种低氧、低粘度的生物油，适合在现有的石油炼油厂中直接加工。该项目旨在开发一种涉及废生物质和废塑料共热解的新工艺，以生产出低氧、低粘度的生物油。产生一系列气体和蒸气，然后直接进入低温（< 200 C）非热等离子体催化反应器，在其中对生物油进行升级以生产低氧优质生物油。废塑料的作用是在生物油升级过程中充当氢供体。该项目涉及新型两级实验室规模反应器的实验工作，以及使用一系列分析技术对成品油和气体进行分析。实验将寻求优化等离子体催化工艺条件，通过对产品油和气体的详细分析，最大限度地提高生物油脱氧效果。此外，该研究的一个关键主题是开发在等离子体催化环境中有效的新型催化剂。该项目旨在开发一种新的低能耗工艺来生产升级生物油，从而使不断发展的热解生物油行业受益。此外，还提供了一种从废弃生物质和废塑料中获取高价值产品的新途径。
