Dewaxing Technique was reconized as the removal of waxy materials from the lubriating distillates for the purpose of the improvement of the low temperative fluidity of the lubricating oils. Recently this technique is developed not only the removal of the waxy materials but the reformation of the waxy materials which does not effect the low temperative fluidity of the lutricating oils. The cutalytic dewaxing technique is developed is this letter direction. And so I insist here the defintion of dewaxing technique must be defined as the technique of the removal and reforming technique of the waxy materials which effect the fluidity of the lubricating oils.
