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

该小型企业创新研究（SBIR）第二阶段项目旨在开发和商业化具有成本效益的高性能大分子抗氧化剂，该抗氧化剂基于Polnox专有的“每分子双型部分”（DT-mPM）技术，用于可持续替代生物油。氧化稳定性是工业生物油的关键问题。这些油来自生物资源，与来自化石燃料的油相比具有较差的稳定性。 特别是，源自植物基多不饱和脂肪酸的燃料和润滑剂特别容易发生严重氧化。已经在阶段I中证明，DT-mPM抗氧化剂在对抗这些生物油的降解方面比最先进的商业抗氧化剂显著更有效。目前，最先进的商业抗氧化剂不能满足植物来源的生物油所带来的挑战。目前的抗氧化剂是为了保护石油润滑剂而开发的，根本无法满足生物润滑剂带来的稳定性问题。 本提案阐述了生物润滑剂用抗氧化剂产品开发中涉及的关键步骤;即，（a）分子设计优化，（B）成本效益工艺放大，（c）第I阶段中确定的磅级铅抗氧化剂的制备，以及（d）产品储存稳定性。该项目更广泛的影响/商业潜力是通过减少空气、土壤、水和生态系统的污染，在减少国家对外国石油的依赖和提供更清洁的环境方面发挥重要作用。增加使用生物润滑剂的社会效益包括减少环境污染的可能性（例如，由于使用过程中的损失或废润滑油处理不当、工业使用过程中的意外溢油或海上钻井而造成的损失），以及减少对进口石油作为原材料的依赖。 然而，由于油是从可再生替代能源开发的，因此存在一些需要解决的固有问题：（1）热氧化稳定性，和（2）倾点性质。 通过开发和商业化新的高性能抗氧化剂来解决生物油的热氧化稳定性问题，这将能够生产可生物降解和环境安全的更高质量的替代油。

This Small Business Innovation Research (SBIR) Phase II project proposes to develop and commercialize cost-effective high performance macromolecular antioxidants based on Polnox's proprietary "dual type moiety per molecule" (DT-mPM) technology for sustainable-alternate bio-oils. Oxidative stability presents a key issue for industrial bio-oils. These oils, which are derived from bio-resources, have inferior stability compared those derived from fossil fuels. In particular, fuels and lubricants derived from plant-based polyunsaturated fatty acids are especially prone to severe oxidation. It has been demonstrated in Phase I that the DT-mPM antioxidants are significantly more effective in combating degradation of these bio-oils vs. state-of-the-art commercial antioxidants. The current, state-of-the-art, commercial antioxidants do not meet the challenges posed by plant-derived bio-oils. Current antioxidants were developed to protect petroleum lubricants and are simply not capable of meeting the stability issues posed by bio-lubricants. This proposal addresses the key steps involved in the product development of antioxidants for bio-lubricants; namely, (a) molecular design optimization, (b) cost-effective process scale up, (c) preparation of pound scale of lead antioxidants identified in Phase I, and (d) product storage stability. The broader impact/commercial potential of this project is to play an important role in reducing the nation's dependence on foreign oil and providing a cleaner environment by reducing the pollution of air, soil, water, and the eco-system. Societal benefits from the increased use of bio-lubricants include less potential for environmental pollution (e.g., from loss during use or improper disposal of waste lubricants, accidental oil spillage during industrial use, or off-shore drilling) as well as reduced dependence on imported petroleum as a raw material. However, as oils are developed from renewable alternate energy resources, there are some inherent issues to be addressed: (1) thermo-oxidative stability, and (2) pour-point properties. By addressing the thermo-oxidative stability problem of bio-oils through the development and commercialization of new high performance antioxidants, this will enable the production of higher quality alternate oils that are biodegradable and environmentally safe.
