《Removal of Basic Nitrogen Compounds from Coker Diesel by Eutectic Ionic Liquid》
Conditions:temperature=30°C，EIL/oil mass ratio=1:7，extraction time=30 min，settling time=120 min
The regeneration of TEAB-Mal was performed by the back extraction of N-compounds with petroleum ether The regenerated EIL was used for further extraction of fresh coker diesel under the same operating conditions Table 2 shows the efficiency for removal of basic N-compounds by using the regenerated EIL.It can be seen that a basic N-compounds removal efficiency of 62.9%could be obtained with the regenerated EIL after four cycles.This result was very significant for the applications of EIL because of the facile recycling outcome.Nevertheless，the denitrogenation efficiency of the regenerated EIL decreased as compared with that of fresh EIL.The possible reason was that the N-compounds which were already dissolved in EIL，could not be reextracted completely by petroleum ether.In view of this further study on more efficient methods for regeneration of the EIL will be carried out later.
