Conversion of Waste Plastic to Oil: Direct Liquefaction versus Pyrolysis and Hydroprocessing

摘要

Two approaches for the conversion of waste post consumer plastic (PCP) into oil have been investigated: (1) direct liquefaction and (2) pyrolysis followed by hydropcessing of the pyrolysis liquids. The PCPs investigated were a washed PCP provided by the American Plastic Council (APC) and a PCP prepared by dry preparation methods provided by the Duals System Deutschland (DSD). The DSD plastic contained signficantly more ash, paper, dirt, and chlorine than the APC plastic and is considered to be more representative of true waste PCP.
