The results showed high class PbSt2 could be synthesized by this new saponifying process.Compared with metathetical process,the reaction time shortened,liquid-solid ratio and moisture content of filter cake decreased.Powder product could be prepared by one-step process,and particle product by two-step process.For the optimum processing conditions,the reaction temperature and time for one-step process were 65℃ and 10min,the amount of alkali added in the first step was 50%;reaction temperture and time were 65℃ and 10min for the two-step process.

结果表明，用皂化法工艺可得到优等品PbSt2，较复分解工艺，反应时间缩短、液-固比降低、滤饼湿含量比减小，一步式工艺得到粉状产品，二步式工艺得到颗粒状产品；最佳工艺条件为：一步式工艺反应温度65℃，反应时间10min；二步式工艺第一步的加碱量比50%，反应温度65℃，反应时间10min。

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.
