- Abstract
Taking the coking kerosene fraction of a refinery as the raw material, the complex extraction process is used to refine the α-olefins and alkanes in the raw oil. The influence of different complex extraction agents and operating conditions such as temperature on the refining was investigated. It was characterized and analyzed. The results showed that: Ag+ reagent 1-N-methylpyrrolidone (NMP) was selected as the complexing extractant, and the extraction temperature was 120℃, the mass ratio of agent to oil was 0.5:1, and the laboratory-made adsorbent was used. Under the conditions, the refining effect is the best. The oil yield of the refined product obtained through the experiment is 83.45%. The mass fraction of purified α-olefin was 70.07%. The removal rate of sulfur could reach 29.73%, and the removal rate of nitrogen could reach 66.09%. The carbon number distribution of refined oil was mainly between C8 -C14. The FT-IR characterization results showed that the functional groups contained in the coking kerosene fraction were mainly O-H,C-H and RCH=CH2,and the obtained refined oil could be used for poly reaction to generate PAO.
