SBIR Phase I: Novel Antioxidants to Improve Thermo-Oxidative Stability of Biolubricants and Biodiesel

该小型企业创新研究（SBIR）第一阶段项目旨在设计、开发具有成本效益、高性能、创新的抗氧化剂，并将其商业化，用于可持续替代生物能源燃料，特别是生物柴油和生物润滑剂。与化石燃料油相比，生物油的氧化稳定性较差。这是替代能源产业的一个关键问题。预计所提出的抗氧化剂在提高热氧化稳定性方面将被证明是非常有效的。这种增强的稳定性将导致延长的使用寿命。面对植物源性生物油的挑战，目前的商业抗氧化剂并不有效，而且这些抗氧化剂的性能并不一定随浓度线性增加。有必要设计和开发比现有抗氧化剂更有效的下一代抗氧化剂。本文提出了一种新型大分子抗氧化剂的设计和测试方法，旨在为生物能源燃料和润滑油提供更好的抗氧化保护。该研究项目的更广泛/商业影响将是开发一种产品，通过开发更高质量的替代燃料，在减少国家对进口石油的依赖方面发挥关键作用。通过提高生物基油和燃料的氧化稳定性，将有可能制造出可行的产品，与汽车和其他工业润滑油应用中使用的石油基产品竞争。

This Small Business Innovation Research (SBIR) Phase I project proposes to design, develop and commercialize cost-effective, high performance, innovative antioxidants for sustainable alternate bioenergy fuels, in particular, for biodiesel and biolubricants. Oxidative stability of oils derived from bio-sources is inferior as compared with those derived from fossil fuels. This is a key issue for the alternate energy industry. It is expected that the proposed antioxidants will prove to be very effective in improving thermo-oxidative stability. This enhanced stability will result in an extended service life. The current commercial antioxidants are not effective in face of the challenge posed by plant-derived bio-oils, and the performance of these antioxidants does not necessarily increase linearly with concentration. There is a need to design and develop next generation antioxidants, which are more effective than those that are available today. This proposal addresses the design and testing of new macromolecular antioxidants to provide better protection against oxidation in bio-energy fuels and lubricants.The broader/commercial impact of this research project will be in the development of a product that plays a key role in reducing the nation's dependence on imported oil by developing higher quality alternate fuels. By improving the oxidative stability of bio-based oils and fuels, it will be possible to make viable products to compete against petroleum based products that are used in automobile and other industrial lubricant applications.
