Abstract—Waste oil contains a variety of contaminants, including lead, magnesium, copper, zinc, chromium, arsenic, chlorides, cadmium, and chlorinated compounds. One gallon of waste oil can foul a million gallons of drinking water. This work identify a unique method by which the spent oil is adequately recycled for reuse, the cost of recycling is relatively low compared from its production from crude oil as the numbers of purification stages are reduced. The Waste automotive engine oil was pyrolyzed in a continuous stirred bed reactor using microwave energy as the heat source; the yield and characteristics of the incondensable gaseous products are discussed. Examination of the composition of the gases is carried out and investigated. The experiment was carried out in a microwave reactor over an activated carbon, which acts as a microwave receptor. Operating temperature (from 200 to 1000 ºC), controlled by power of microwave reactor, was varied to observe the consequence on the pyrolysis products. The chemical composition and product yield of the pyrolysis products (liquid oil and gas) were analyzed by using gas chromatography/mass spectrometry (GC/MS). The effects of both N2 and waste oil flow rates on both the aliphatic and aromatic components are carried out and investigated. The effect of the microwave pyrolysis temperature on the pyrolysis products and the microwave pyrolysis energy are obtained.
