SBIR Phase II: Neutralizing Utility Mercury Control Sorbents for Fly Ash Use in Concrete

这个小型企业创新研究第二阶段项目建议优化和商业应用一种新发现的碳材料，该材料同时显示出对汞的高气相吸附和对有机表面活性剂的低湿混凝土吸附。如果燃煤发电厂要以较低的成本改造吸附剂注入技术，以符合汞排放的新限制，同时继续将其飞灰废物作为混凝土建筑应用中的水泥替代品出售，这种材料是必要的。该材料将在中试和全尺寸进行测试，为产品商业化铺平道路。该项目可能产生的更广泛影响将是一个严重的悬而未决的经济和环境问题的解决方案。在建筑应用中用电厂飞灰替代人造波特兰水泥是美国最大的回收成功之一。飞灰可以降低建筑业混凝土的成本，提高混凝土的技术性能，并通过节约能源、减少废物处理和二氧化碳排放来保护环境。

This Small Business Innovation Research Phase II project proposes to optimize and commercially apply a newly discovered carbon material that simultaneously exhibits high gas-phase adsorption of mercury and low wet-concrete adsorption of organic surfactants. Such a material is necessary if coal-fired power plants are to inexpensively retrofit sorbent-injection technology to comply with new limits on mercury emissions while continuing to sell their fly ash wastes as substitutes for cement in concrete construction applications. The material will be tested at both the pilot and full scales, paving the way for product commercialization. The broader impact that could be achieved from this project will be a solution a serious pending economic and environment problem. The substitution of power-plant fly ash for manufactured Portland cement in construction applications is one of America's biggest recycling successes. Fly ash could lower the construction-industry concrete costs, increase the technical performance of the concretes, and preserve the environment by conserving energy and reducing both waste disposal and CO2 emissions.
