In this study, a new arranged catalyst support with distinct open pore morphology has been fabricated via thermal oxidation of an FeCrAl alloy with an aim to address mass transfer limitations that conventional supports have due to their internal porosity. Subsequent characterization tests including, drop shape analysis, X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy revealed that the support formed upon thermal oxidation for 1 hour at 930C, 1 hour at 960C and 2 hours at 990C embodies advantageous support characteristics. Preliminary tests were performed using palladium (active component) deposited on the new support in representative three phase hydrogenation reactions of 2-methyl-3-butyn-2-ol or 2-methyl-3-buten-2-ol. Absence of mass transfer limitations was verified for 2-methyl-3-buten-2-ol hydrogenation at 35-50C, 1200 rpm stirring speed and 0.46 MPa pressure of hydrogen in a 300 ml semi-batch reactor using ethanol as solvent. The study paves the way to the development of arranged catalysts based on FeCrAl alloy fibers for structured reactors. / Chemical Engineering
