Abstract
The ortho-parahydrogen conversion was investigated on a series of Cr2O3-Al2O3 catalysts by the static method at 77°K and under various pressures. The results are shown in Figures 1, 2 and 3. A series of chromia-alumina impregnated catalysts in the range 0–3 percent Cr2O3-Al2O3 were compared with a number of commercially available catalysts in the range 20 to 35 percent Cr2O3-Al2O3. Approximately 0,7 gram mol of hydrogen was used in contact with 200 cc of each catalyst tested. It was found that the conversion followed first order kinetics (see Figures 4 and 5) and that the 1 percent catalyst gave approximately the same rate constant as the fastest commercial catalyst tested (see Figure 6).
