LIQUEFACTION OF AUTOFLUFFS WITH PRODUCT OILS RECYCLING

The resource recovery of autofluff (auto shredder residue) is of incre asing importance as incineration and land filling become much more exp ensive and the acceptance of these methods is decreasing. Thus, the ma in purpose of this world was to investigate the feasibility of the aut ofluff liquefaction. The liquefaction process involves contacting the autofluff wastes with hot motor oil to recover valuable oil products E xperimentally, liquefaction of autofluff in hot used motor oil generat ed approximately 70.9% of oils, and 2.0% of noncondensible gases and 2 7.1% of nonliquefible solid residues. Proton NMR and FTIR spectroscopi c, data reveal the structural changes of oils that occur during autofl uff liquefaction. The cuts of the condensate produced from the autoflu ff liquefaction into weighted boiling fraction are primarily light nap htha and heavy gas oil Light naphtha is the main constituents of gasol ine. Heavy gas oil may be re-refined into lighter products or sold as a low grade fuel oil.
