介绍了用常压微反和加压原粒度活性检测装置，对国产Ｂ１１９型与前西德产Ｇ－３型催化剂活性、径向抗压碎强度、热稳定性等数据，进行了测定。结果表明，Ｂ１１９型各项性能达到了国产化的要求并可替代Ｇ－３型催化剂。
This paper introduced the measurement of the activity, radial crushing strength and thermal stability of domestic B119 and former West German G-3 catalysts by using the device of atmospheric pressure microdistillation and pressurization. The results showed that the properties of B119 reached the requirements of localization and could replace G-3 catalyst.
