The TOP (Total Oil Processing)-NEDOL process for producing high quality liquefied oil with decreasing the hetero-compounds was designed, and a part of flow of the NEDOL process in the PSU was rearranged. In this paper, the results of the demonstrating experiments using the 1t/d PSU were reported under the TOP-NEDOL process systems. As the results, in the TOP-NEDOL process, the oil yield increased and the hetero-compounds in the liquefied oil decreased compared with the NEDOL process.
