摘　　要：采用NH_3-TPD法,利用FINESORB-3010程序升温化学吸附仪测定固体催化剂表面酸性。研究样品量、样品的预处理、炉温和程序升温速率、反应气和载气流速、桥电流设置以及气体选择等对测定固体催化剂酸性的影响。Ammonia temperature-programmed desorption technique（NH_3-TPD） is used for the characterization of surface acidity of solid catalyst via FINESORB-3010 Chemisorption Analyzer.The effects of some parameters such as sample quantity and pre-treatment,furnace temperature and temperature-programmed rate,the reaction gas and carrier gas flow rate,bridge current,chosen gas on the acidity of solid catalyst,are studied in detail.

关 键 词：程序升温脱附法 固体催化剂 酸性
