75.石炭を用いた廃潤滑油のリサイクル技術開発(2) : 処理条件の脱金属効果におよぼす影響とメカニズム

抄録

The responsible management of used luburicating oils to minimize pollution is a major concern in the world. This concern for environmental protection may increase the percentage of renewal luburicating oils in the furture. The recycling technology of used lubricating oils to remove chroride and metal components by heating and adsorption using low rank coal was investigated. In this paper, the effect of treating conditions on demetalization and removal mechanism of each component were discussed.
