【摘要】 加氢反应器是石油化工行业的关键设备，由于长期工作在高温、高压环境中，要求附着在其器壁上用于测定原子氢的传感器具有较好的高温工作特性．研制一种用镍电极作为参比电极的三电极系统化学传感器，试验了该传感器的基本性能，确定了氢渗透时原子氢氧化的最佳氧化电位为0．4V（vsNi）．更多还原

【Abstract】 Hydrogenation reactor is key equipment in the petroleum refinery industry. The sensor attaohed to the wall of the reactor for measuring atomic hydrogen in metals must have good workingcharacteristics since the reactor operates in the circumstance of elevated temperature and high pressure.A electrochemical sensor with three-electrode system is developed by using nickel as reference electrodeThe proterties of the sensor are tested. The optimum oxidiZing potemtial is determined as 0.4 V vs nickel electrode.更多还原
