在以往工作的基础上,提出了用气相色谱法(GC)对催化反应、化学吸附和气体扩散进行联合研究的设计,建立了相应的装置,并拟投入定型化仪器生产.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.
Based on the previous work, the design of the joint research on catalytic reaction, chemisorption and gas diffusion by gas chromatography (GC) has been put forward and the corresponding device has been established and put into the production of the finalized equipment.According to the requirements, it can be used Pulse method, continuous flow method, head-on method, and temperature-programmed desorption technique, the catalyst reaction speed, the metal dispersion or other active sites, the surface pH and the mass transfer performance are determined one by one on a set of equipment so as to refer to the entire catalytic process A variety of in situ data to effectively improve the catalyst activity, selectivity and life expectancy.
