【摘要】 在直径25毫米的固定床内,用乙烯氧化制环氧乙烷的催化剂和邻二甲苯氧化制苯酐表面涂层催化剂的载体作为填料,在工业反应器实际操作的雷诺数范围内和相近的温度水平下,对床层的传热特性进行了实验研究,得到了计算传热参数的关联式。更多还原

【Abstract】 The heat transfer characteristics of a 25mm interal diameter fixed-bed packed with the selective oxidation catalysts of ethylene or O-xylene are xperimentally studied under the conditions similar to those for the commercial reactors in temperature and hydrodynamics. The correlations for calculating the effective heat fransfer parameters of the small diameter packed-beds are presented based on the data obtaineod in this work.更多还原
