摘要
中石化石油化工科学研究院有限公司历经30年持续创新,成功开发尼龙-6单体己内酰胺绿色生产技术,主要包括:环己烯酯化加氢制环己酮绿色合成新途径,空心TS-1分子筛与浆态床集成用于环己酮氨肟化,S-1分子筛与移动床集成用于环己酮肟气相贝克曼重排,非晶态镍催化剂与磁稳定床集成用于己内酰胺精制.与引进己内酰胺生产技术相比,碳原子和氮原子利用率明显提升,三废排放显著减少,无副产低价值硫酸铵,装置投资大幅下降,生产成本明显减少.
Abstract
After 30 years of continuous innovation,SINOPEC Research Institute of Petroleum Processing Co.,Ltd.has successfully developed green production technology for nylon-6 monomer caprolactam,it included a new green synthesis pathway for cyclohexanone by cyclohexene esterification and hydrogenation,the integration of hollow TS-1 zeolite with the slurry-bed reactor for the ammoximation of cyclohexanone,the integration of silicalite-1 zeolite with the moving-bed reactor for the gas-phase rearrangement of cyclohexanone oxime and the integration of an amorphous nickel catalyst with the magnetically stabilized bed reactor for the purification of caprolactam.Compared with the import technology of caprolactam production,the utilization rate of carbon atom and nitrogen atom were obviously increased,the emission of"three wastes"was significantly reduced,no low-value by-product ammonium sulfate was produced,the investment of the plant was greatly reduced,and the production cost was obviously reduced.
