合成尿素CO_(2)原料气氢氧复合脱除H_(2)催化剂的研究

Study on hydrogen-oxygen complex catalyst for removal of hydrogen from CO_(2) feedstock for urea synthesis

针对合成尿素CO_(2)原料气脱除杂质H_(2)的需求,大连凯特利催化工程技术有限公司开发了适用于CO_(2)原料气氢氧复合脱H_(2)催化剂H-845。考察床层高径比、空速和压力等因素对脱氢催化剂性能的影响。500 h催化剂稳定性测试结果显示,该催化剂可以有效脱除CO_(2)中的H_(2),满足尿素合成指标。

Dalian Catalytic Engineering Technology Co.,Ltd.developed a H-845 catalyst for removing impurity H_(2) from CO_(2) feed stream for urea synthesis.Effects of bed height diameter ratio,space velocity and pressure on behaviors of the hydrogen removal catalyst were investigated.500-hour catalyst stability test results showed that the catalyst can effectively remove H_(2) impurity in CO_(2) to level qualifying for urea synthesis.
