摘要
介绍了NCH6-2A型辛烯醛气相加氢催化剂在丁辛醇工业化生产装置上的应用情况,并对催化剂进行了标定。考察了在该催化剂存在下辛烯醛的转化率和辛醇的选择性,同时对影响产品硫酸色度的原因进行了分析和验证。应用结果表明:该催化剂辛烯醛转化率和辛醇选择性均达到并超过了以前使用进口催化剂及NCH6-2型催化剂的水平,经济效益显著。
The industrial application status of NCH6-2A type catalyst for producing 2-ethylhexenal by gas phase hydrogenation is introduced, and the performances of the catalyst such as the conversion of 2-ethylhexenal and selectivity of 2-ethylhexanol are investiga- ted. In the meantime, the influencing factors of sulfuric acid color index of product are analyzed and verified. The application results show that the conversion of 2-ethylhexenal and selectivity of 2-ethylhexanol are both higher than those of the imported catalyst and NCH6-2 catalyst, the economic benefits is obvious.
