用N-甲酰吗啉萃取精馏分离苯加氢油中的烷烃

Separation of Alkane from Hydrorefining Raffinate Using N-formylmorpholine with Extractive Distillation Process

通过对苯加氢油萃取精馏溶剂性能的比较表明,N-甲酰吗啉在选择性、热稳定性、化学稳定性、腐蚀性和毒性等均优于其他溶剂,可作为分离焦化苯加氢油中微量烷烃的优良溶剂。

The comparison of the properties of solvents for hydrorefining raffinate extractive distillation shows that N-formylmorpholine is better than the other solvents in selection , thermal stability,chemical stability, corrosion toxicity and so on. It is a better solvent for the separation of trace alkane from the hydrorefining raffinate.
