摘要
在糠醛精制过程中添加脱氮组分,采用物理抽提与化学反应相结合的方法对模拟基础油进行脱碱氮研究.考察了剂油比、脱氮组分浓度、反应温度及沉降时间等精制条件对脱碱氮效果及脱氮组分在油中残留的影响.结果表明脱碱氮率随脱氮组分浓度和剂油比的增加而升高;脱氮组分残留量随脱氮组分浓度增加而增加,随剂油比增大而减少;温度升高,脱碱氮率下降,残留量增加;沉降时间增长,脱碱氮率上升,残留量降低.
The research of furfural refining adding denitrogenation agents by the method of combining physical extraction and chemical reaction has been done. The influence oi different factors such as concentration of denitrogenation agents, solvent/oil ratio, refining temperature and settling time on the effect of the basic nitrogen removal rate and the residual of denitrogenation agents in the oil is investigated. The results indicate that the basic nitrogen removal rate increases with the concentration of denitrogenation agents and solvent/ oil ratio increasing, and the residual of denitrogenation agents increases with the concentration of denitrogenation agents increasing and reduces with the solvent/ oil ratio increasing. The basic nitrogen removal rate decreases when refining temperature rises while the residual of denitrogenation agents increases. It is opposite to the settling time.
