The RF-DPF Diesel Particulate Filter Sensor was developed by Filter Sensing Technologies Inc., in collaboration with ORNL and Massachusetts Institute of Technology. The ORNL team consisted of James Parks II, Vitaly Prikhodko, and John Storey.
The RF-DPF is a radio frequency-based sensor and control system used to measure the amount, type, and distribution of contaminants on filters. This technology provides rapid real-time assessment of soot on diesel particulate filters, which allows greater precision in filter control, thereby reducing fuel consumption and greenhouse gas emissions. The RF-DPF can be used with light- and heavy-duty diesel vehicles and may enable longer filter life and overall system cost savings.
The project was funded by Filter Sensing Technologies Inc., and the DOE Vehicle Technologies Office.
Super-hydro-tunable HiPAS Membranes were developed by ORNL. Inventors were Michael Hu, Matthew Sturgeon, Ramesh Bhave, Brian Bischoff, Tolga Aytug and Tim Theiss.
This new class of membrane products can selectively separate molecules in the vapor/gas phase and perform liquid-phase separations, which could be especially useful in reducing the price of bio-ethanol, ethanol-gasoline blend fuels and drop-in fuels from bio-oil processing. The membrane acts as an energy-efficient alternative to the distillation process by using a superhydrophobic or superhydrophillic surface to separate molecules. The membrane's larger pore sizes and architecture advantages drive never-before-achieved flow rates across membranes, sustaining characteristics key to repetitive or continuous operation under high pressures and temperatures. In addition to its potential in biofuel-based economies, these membranes could have a broad impact in chemical, pharmaceutical, petrochemical and gas separation industries.
