Abstract

The major objective of this work was to investigate the feasibility of rubber wastes liquefaction process with product oils recycling. The liquefaction process involves contacting the rubber wastes with hot motor oil. Experiments were conducted in a 24 TPD waste liquefaction pilot plant. Liquefaction of rubber wastes recovers approximately 95% of oils, 3% of noncondensible gases and 2% of nonliquefiable solid residues. Fuel characteristics of the liquefaction product oils were evaluated by standard oil analysis procedures and spectroscopic methods. The cuts of the condensate produced from the rubber liquefaction into weighted boiling fraction are primarily naphtha (38.9%) and gas oil (60.6%). Naphtha is the main constituents of gasoline. Gas oil may be re-refined into lighter products or sold as a low grade fuel oil. The product heavy oils recovered from liquefaction of rubber wastes contain noticeable amounts of gas oil (96.6%). The gas oil may be further hydrotreated and cracked to gasoline and diesel fractions.
