Experimental Study of Reaction Kinetics for Para-Orthohydrogen at 20° to 80°K
This paper presents studies of the conversion of parahydrogen to orthohydrogen over a temperature range of 20° to 80°K and a pressure range of 20 to 1000 psig. The reaction was a catalyzed reaction using a standard ferric oxide gel catalyst of size 30–50 mesh. The purpose of the investigation was a detailed study of the mechanism of the reaction, with the immediate goal of providing accurate design information and an ultimate goal of developing more active catalysts. The data from such a study are more easily interpreted for isothermal reactor conditions. Steady-state temperature and pressure conditions are also required. The design and construction of an apparatus which was devised to meet the specifications listed above is outlined and the data obtained from the system are presented.
