Waste engine oil, waste plastic products and waste rubber products like tires, are generated and left behind by human beings in the process of living activities and production activities, which can continue to be processed and utilized by human science and technology at present. However, if not properly handled, they will pollute the environment, waste resources, and badly influences production and our life. 

Distillation with catalyst technology is a hybrid design that utilizes the dynamics of simultaneous reaction and separation in a single process unit to achieve a more compact, economical, efficient and optimized process when compared to the traditional multi-unit designs. The new distillation technology could separate different fractions of the waste oil by temperature control. And then use catalysts to crack and absorb the heavy fraction, thus to light oil. In this distillation process, we use catalysts instead of chemicals, which would not generate chemical pollution to the environment.
