Flutter test analysis in the time domain using a recursive system representation

nation with hydrogen. This has been specifically considered with major fuel properties such as sulfur content, smoke point and thermal stability. The extensive degree of sulfur removal by a cobalt molybdate catalyst and aromatics saturation by a noble metal catalyst have been cited. This plus the effect of temperature, pressure and other reactor variables have illustrated the flexibility of the process, which gives uniquely high yields of quality product without a waste disposal problem.
