A study the Oil Recovery by Pyrolysis from Waste Pleastics (HDPE, PP) through Olivine

摘要

PURPOSE: A process of recovering oil from waste plastic by adding a suitable additive such as olivine and controlling a thermal cracking process is provided, thereby increasing the recovery rate of oil and plastic material. CONSTITUTION: Olivine is mixed with waste plastic(HDPE, PP) in a ratio of 1:20 in a thermal cracking apparatus, the temperature of the apparatus containing the mixture is raised to 300 to 500deg.C at a speed of 5deg.C/min and then thermally cracked at 420deg.C for 0 to 200min.
