【摘要】 绿色化学的理想是实现反应的"原子经济"性,生产环境友好的绿色产品,这就要求原料中的每一个原子进入产品,不产生废物和副产品,并采用无毒无害的原料、催化剂和溶剂。根据绿色化学的理念,中国石化石油化工科学研究院历经20年,开发成功己内酰胺绿色生产技术,建成20万t/a工业生产装置。这项技术包括:单釜连续淤浆床与钛硅分子筛集成用于环己酮氨肟化合成环己酮肟;非晶态合金催化剂与磁稳定床集成用于己内酰胺加氢精制。工业实施后,使装置投资下降70%、生产成本下降10%、原子利用率由60%提高到90%以上,三废排放是引进国外技术路线的1/200,产生了重大经济效益和社会效益。己内酰胺绿色生产技术的开发,践行了绿色化学的理念,是绿色化学的成功范例。更多还原

【Abstract】 Ideal of green chemistry is the reaction of "atom economy" and production of environment-friendly green products.This requires that every atom in the raw materials entry into the product,no waste and by-products are produced,and the poisonous and harmful materials are not used in the process.To practice the concept of green chemistry,Research Institute of Petroleum Processing have developed the green caprolactam production technology successfully and constructed a commercial unit which the productivity is to be 2×105 t/a.The innovation technology includes: single-vessel continuous slurry bed integration with titanium silicate zeolite for cyclohexanone ammonization,and amorphous alloy catalyst integration with magnetically stabilized bed for purification of caprolactam.Based on the commercial application,the investment of the caprolactam production plant has decreased 70%,the operation costs decreased 10%,the atom utilization increased from 60% to 90%,and there are waste-free essentially,respectively.The green caprolactam production technology has well practiced the green chemistry concepts and became a successful example of green chemistry.更多还原
