Abstract:

Initial adsorption heat of benzene on NaHY of different Na:H ratios have been determined in the temperature range of 250--300 ℃ by gas chromatographic pulse method. It was found that the adsorption heat decreases stepwisely with the decrease of Na content in NaHY: It is 62.4 kJ·mol~(-1) for Na:H<0.6, 60.3 kJ·mol~(-1) for 0.14
