摘要:
针对某裂解汽油加氢装置氢气中CO体积分数(1 000×10-6以上)较高的情况,分析了CO对裂解汽油二段加氢催化剂LY-9802加氢性能的影响,考察了催化剂LY-9802的工业应用效果。结果表明:催化剂LY-9802能使氢气中的CO部分加氢生成CH4,随着反应温度升高,CO转化率和CH4生成率均提高,但CO转化率不超过60%;在氢气中CO体积分数为1 400×10-6,反应器入口温度为245~260 ℃的小试加氢反应条件下,产物溴价为0.005~0.008 g/g,含硫量为0.5~0.8 μg/g,当入口温度分别为265,275 ℃时,产物溴价分别小于0.005,0.001 g/g,含硫量分别小于0.5,0.1 μg/g,提高入口温度能有效恢复并提升催化剂活性;在加氢反应器二段入口温度为280~320 ℃的工业生产条件下,床层温升在40~60 ℃波动,加氢产品溴价不大于0.001 g/g,含硫量不大于0.5 μg/g。
Abstract:
The effect of CO resistance performance on the second- stage hydrogenation catalyst LY-9802 of pyrolysis gasoline was studied in view of the high CO volume fraction of hydrogen (more than 1 000×10-6) in some pyrolysis gasoline hydrogenation units. And the industral application of catalyst LY-9802 was investigated. The results showed that CH4 was produced from CO on the second stage hydrogenation catalyst. As the reaction temperature increased, both CO conversion rate and CH4 generation rate increased, but the CO conversion rate did not exceed 60%. Under the small-scale hydrogenation reaction conditions with CO volume fraction of 1 400×10-6 and inlet temperature of 245-260 ℃, the bromine value of the product was 0.005-0.008 g/g, and the sulfur content was 0.5-0.8 μg/g. When the inlet temperature was 265 and 275 ℃, the bromine value of the product was less than 0.005 and 0.001 g/g, and the sulfur content was less than 0.5,0.1 μg/g,respectively. Increasing the inlet temperature could effectively recover and enhance the catalyst activity.The industrial operation results showed that at the reactor inlet temperature 280-320 ℃,and temperature rise of the bed between 40-60 ℃,the bromine value of hydrogenation product was less than 0.001 g/g and the sulfur content was less than 0.5 μg/g, which all met the index requirements.
