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

这个小型企业创新研究(SBIR)二期项目计划开发高性价比的高性能高分子抗氧化剂，并将其商业化，该抗氧化剂基于Polnox专有的用于可持续替代生物油的“每分子双类型部分”(DT-MPM)技术。氧化稳定性是工业生物油的一个关键问题。这些来自生物资源的石油与来自化石燃料的石油相比，稳定性较差。特别是，来自植物性多不饱和脂肪酸的燃料和润滑剂特别容易发生严重的氧化。在第一阶段已经证明，与最先进的商业抗氧化剂相比，DT-MPM抗氧化剂在对抗这些生物油的降解方面明显更有效。目前最先进的商业抗氧化剂无法应对植物衍生生物油带来的挑战。目前开发的抗氧化剂是为了保护石油润滑剂，根本不能满足生物润滑剂带来的稳定性问题。该建议涉及生物润滑剂抗氧化剂产品开发的关键步骤，即(A)分子设计优化，(B)具有成本效益的工艺放大，(C)制备第一阶段确定的磅规模的铅抗氧化剂，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益处包括减少环境污染的可能性(例如，在使用过程中损失或不当处置废润滑剂、工业使用过程中的意外漏油或近海钻井)，以及减少对进口石油作为原材料的依赖。然而，由于石油是从可再生的替代能源中开发出来的，因此有一些固有的问题需要解决：(1)热氧化稳定性，(2)凝点性质。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，这将使生产可生物降解和环境安全的更高质量的替代油成为可能。

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.
