Development of OTM Syngas Process and Testing of Syngas Derived Ulta-clean Fuels in Diesel Engines and Fuel Cells Budget Period 3

This topical report summarizes work accomplished for the Program from January 1, 2003 through December 31,2004 in the following task areas: Task 1--Materials Development; Task 2--Composite Development; Task 4--Reactor Design and Process Optimization; Task 8--Fuels and Engine Testing; 8.1 International Diesel Engine Program; and Task IO: Program Management. Most of the key technical objectives for this budget period were achieved. Only partial success was achieved relative to cycle testing under pressure Major improvements in material performance and element reliability have been achieved. A breakthrough material system has driven the development of a compact planar reactor design capable of producing either hydrogen or syngas. The planar reactor shows significant advantages in thermal efficiency and costs compared to either steam methane reforming with CO{sub 2} recovery or autothermal reforming. The fuel and engine testing program is complete The single cylinder test engine evaluation of UCTF fuels begun in Budget Period 2 was finished this budget period. In addition, a study to evaluate new fuel formulations for an HCCl engine was completed

Novel Reactor for the Production of Synthesis Gas

Praxair investigated an advanced technology for producing synthesis gas from natural gas and oxygen This production process combined the use of a short-reaction time catalyst with Praxair's gas mixing technology to provide a novel reactor system. The program achieved all of the milestones contained in the development plan for Phase I. We were able to develop a reactor configuration that was able to operate at high pressures (up to 19atm). This new reactor technology was used as the basis for a new process for the conversion of natural gas to liquid products (Gas to Liquids or GTL). Economic analysis indicated that the new process could provide a 8-10% cost advantage over conventional technology. The economic prediction although favorable was not encouraging enough for a high risk program like this. Praxair decided to terminate development

Two-Dimensional Compact Variational Mode Decomposition

Decomposing multidimensional signals, such as images, into spatially compact, potentially overlapping modes of essentially wavelike nature makes these components accessible for further downstream analysis. This decomposition enables space–frequency analysis, demodulation, estimation of local orientation, edge and corner detection, texture analysis, denoising, inpainting, or curvature estimation. Our model decomposes the input signal into modes with narrow Fourier bandwidth; to cope with sharp region boundaries, incompatible with narrow bandwidth, we introduce binary support functions that act as masks on the narrow-band mode for image recomposition. L1 and TV terms promote sparsity and spatial compactness. Constraining the support functions to partitions of the signal domain, we effectively get an image segmentation model based on spectral homogeneity. By coupling several submodes together with a single support function, we are able to decompose an image into several crystal grains. Our efficient algorithm is based on variable splitting and alternate direction optimization; we employ Merriman–Bence–Osher-like threshold dynamics to handle efficiently the motion by mean curvature of the support function boundaries under the sparsity promoting terms. The versatility and effectiveness of our proposed model is demonstrated on a broad variety of example images from different modalities. These demonstrations include the decomposition of images into overlapping modes with smooth or sharp boundaries, segmentation of images of crystal grains, and inpainting of damaged image regions through artifact detection
