An experimental study on the hydro-cracking of recycling oil obtained from refused plastics was performed for up-grading of its fuel characteristics. Major experimental parameters were reaction temperature ($300^{\circ}C{\sim}700^{\circ}C$) and presence of catalysts (Al-Si, activated carbon, zeolite). The effect of the experimental parameters on the liquid product characteristics such as flash point, kinetic viscosity, and solid content was investigated. The hydro-cracking reactions of the recycling oil at $300^{\circ}C{\sim}400^{\circ}C$ improved the oil characteristics of the liquid products. Activated carbon was revealed as a stable and active catalyst in the hydro-cracking reaction at a temperature range investigated.
