SBIR Phase I: ResonantSonic Advanced Oxidation Reactor

这个小型企业创新研究的第一阶段将由蒙泰克联合公司进行，该项目提出了一种新颖的机械方法，可以引起低频、声能驱动的液体空化，用于先进的氧化反应器。局部高温（5000℃）、高压（几百个大气压）和高剪切力已被证明发生在超声产生的空化气泡中。在空化泡内爆过程中产生的高能环境就像一个“微反应器”，可以启动或加速化学反应。氢氧离子和过氧化氢的生产，作为一种侵略性氧化剂，通过超声诱导空化是有充分记录的。这项被称为ResonantSonics的技术已经在Montec被用于在液体和泥浆中产生低频（例如2000赫兹）的高能量空化。利用低频声波产生空化的能力具有深远的意义，因为它克服了阻碍商业超声波处理应用的严重规模和成本限制。在Montec进行的探索性测试表明，ResonantSonics可以破坏（氧化）氰化物，并大大提高氰化物和氟化物以及重金属从污染材料中的去除效果。这些探索性实验的结果为Montec将ResonantSonics开发为可行的商业高级氧化工艺提供了强大的动力。该技术有可能提供一种可行的声化学方法，适合于有效地扩大规模，以销毁或转化各种危险废物类型。商业应用很多，包括在政府和工业场所处理混合废物和危险废物。＊＊＊

*** 9661341 Farrar This Small Business Innovative Research Phase I to be carried Montec Associates, Inc. project presents a novel mechanical method to cause low-frequency, sonic-energy driven cavitation of liquids for application as an advanced oxidation reactor. Local high temperatures (5000 C), high pressures (several hundred atmospheres) and high shear forces have been demonstrated to occur within cavitation bubbles generated by ultrasonics. The high energy environment created during implosion of the cavitation bubble acts as a "microreactor" to enable and/or to accelerate chemical reactions. The production of hydroxyl ions and peroxide for use as an aggressive oxidant via ultrasonically induced cavitation is well documented. The proposed technology, termed ResonantSonics, has been used at Montec to produce highly energetic cavitation in liquids and slurries at low-frequencies, e.g., 2000 Hertz. The ability to cause cavitation with low-frequency sonics has profound implications, as it overcomes the severe scaling and cost restrictions that have prevented the commercial ultrasonic processing applications. Exploratory tests conducted at Montec have demonstrated that ResonantSonics can destroy (oxidize) cyanide and greatly enhance removal of cyanide and fluoride, as well as heavy metals, from contaminated materials. The results of these exploratory experiments provide a strong motivation for Montec to develop ResonantSonics as a viable commercial advanced oxidation process. The technology has the potential to provide a viable, sonochemical means, suitable for efficient scale-up to destroy or convert a broad range of hazardous waste types. Commercial applications are numerous and include treatment of mixed and hazardous wastes at government and industrial sites. ***
