Abstract
Pyrolysis reaction of waste lubricant oil was studied in a fixed-bed reactor both with and without the presence of a catalyst in the temperature range of 300-400 oC under nitrogen atmosphere. Products are contained two parts including gas and liquid. Liquid products consist of gasoline-like fuel (C7-C10), jet oil-like fuel (C11-C15) and diesel-like fuel (C15-C20), which are desirable for liquid fuels. From the experimental study, the amount of gas product increases with temperature. Additionally, under these studied conditions the amount of gas product in the system without any catalysts was almost the same, approximately 50 wt%. However, for the catalytic system it was found that activated carbon is more suitable for pyrolysis reaction than zeolite catalyst. The optimum operating conditions in this study was at temperature of 400 oC over activated carbon. Liquid products consisting of gasoline-like fuel, jet oil-like fuel and diesel-like fuel are 42, 12, and 14 wt% respectively.
