STTR Phase II: Waste Cooking Oil and Fly Ash Based Bioasphalt

这个小企业创新研究（SBIR）二期项目建议从回收的农业副产品中开发一种高性能、环保、低成本的可再生生物沥青。石油基沥青的供应问题，以及石油的高成本和将沥青从集中炼油厂运输到配送点的燃料价格，大大提高了沥青的价格。石油沥青的使用还会产生碳氢化合物烟雾，这会刺激工人，并对周围社区造成滋扰。由于担心对外国石油的依赖，沥青价格高且供应不稳定，以及空气排放，需要研究和开发利用可再生资源制成的非石油基生物沥青。在第二阶段的研究中，第一阶段开发的生物沥青生产技术将扩大规模，生产样品用于现场评估。这项技术的商业可行性将得到证明。本研究更广泛的影响是使用可再生的农业产品来减少石油沥青的使用，消除与传统石油沥青相关的气味和排放，并提高产品性能。

This Small Business Innovation Research (SBIR) Phase II project proposes to develop a high performance, environmentally benign, and low cost renewable bioasphalt from recycled agricultural byproduct. The availability issue of petroleum based asphalt, along with the high cost of petroleum and the fuel price to transport the asphalt from a centralized refinery plant to distribution sites, has increased the price of asphalt substantially. The use of the petroleum asphalt also generates hydrocarbon fumes, which irritate workers and create a nuisance for the surrounding community. Because of concerns over dependence on foreign oil, a high asphalt price and unstable supply, and air emissions, non-petroleum based bioasphalt made from renewable sources needs to be studied and developed. In this Phase II research, the bioasphalt production technology developed in Phase I will be scaled up to produce samples for evaluation in the field. The commercial viability of this technology will be demonstrated. The broader impacts of this research are the use of a renewable and agricultural based product to reduce the use of petroleum asphalt, eliminate the odor and emissions associated with traditional petroleum asphalt, and improve the product performance.
