根据要求,可以使用脉冲法、连续流动法、迎头法,以及程序升温脱附技术,在一套设备上逐个测定催化剂的反应速度、金属分散性或其它活性中心、表面酸碱度和质量传递性能等,以便参照催化全过程的多种原位数据,有效地改进催化剂的活性、选择性及寿命。在多相催化中,由于反应体系的复杂性,使得再解释催化活性及其机理上遇到了困难,因而妨碍了对特定化学过程最佳催化剂的选择。在近代,虽然有着各种能谱,
Depending on the requirements, the pulse rate, continuous flow method, heading method, and temperature programmed desorption can be used to measure the reaction speed of catalyst, metal dispersion or other active centers, surface pH and mass transfer performance on a set of equipment, In order to refer to a variety of in situ catalytic data throughout the process, effectively improve the catalyst activity, selectivity and life expectancy. In heterogeneous catalysis, the difficulty of re-interpreting the catalytic activity and its mechanism due to the complexity of the reaction system hinders the choice of the best catalyst for a given chemical process. In modern times, although there are all kinds of energy spectrum,
