North Salt Lake City, UT Abstract: Limitation of 15 ppm has been considered for the content of sulfur in diesel fuel due to the sulfur regulation by the EPA. However, ultra low sulfur diesel (ULSD) fuel has not been produced sufficiently by the current desulfurization technology. Various levels of sulfur content can be observed in different diesel fuels, for instance, Valley Oil (8000 ppm), F-76 (4200 ppm) and treated Valley Oil (500 ppm). In this regard, 99.9% removal efficiency in sulfur reduction can be demonstrated by solvent extraction, as well as solid adsorption, which is after the modified ultrasound assisted desulfurization process. Moreover, recycling of ionic liquid and acid catalyst which is usually contained in the spent aqueous phase can be achieved. Interestingly, high efficiency, as well as high selectivity can be exhibited. In the pilot study, unit containing treatment tank, pipeline system, as well as high shear mixer has been created for the development of practical application of a batch-type continuous flow system. In the development, appropriate time and mild condition were given during operations. The results show 99.9% desulfurization efficiency can be achieved by the process. Moreover, utilization of ionic liquid and acid catalyst had been done at a less extent by the pilot study, as compared to the batch study.

Jennifer Rice, Ph.D. Candidate
Civil & Environmental Engineering
University of Illinois at Urbana-ChampaignThe declining state of civil infrastructure has motivated researchers to seek effective methods for real-time structural health monitoring (SHM). Decentralized computing and data aggregation employing smart sensors allow the deployment of a dense array of sensors throughout a structure. The Imote2, developed by Intel, provides enhanced computation and communication resources that allow demanding sensor network applications, such as SHM of civil infrastructure, to be supported. This study explores the development of a versatile Imote2 sensor board with onboard signal processing specifically designed for the demands of SHM applications. The components of the accelerometer board have been carefully selected to allow for the low-noise and high resolution data acquisition that is necessary to successfully implement SHM algorithms.Jennifer Rice received her B.S. in Civil Engineering from Texas Tech University. She received her M.S from the University of Illinois at Urbana-Champaign where her research focused on wind engineering and vibration mitigation devices for light truss structures. She is currently a Ph.D. candidate at the University of Illinois in the Smart Structures Technology Laboratory. Her research interests are in the area of structural health monitoring and wireless sensor networks.
