The co-liquefaction of waste plastics with coal and waste tire rubber with coal was successfully demonstrated at a combined processing rate of 3 TPD at the Proof-of-Concept facility in Lawrenceville, N.J. The POC Program is funded by the U.S. DOE, Hydrocarbon Research, Inc., and Kerr McGee Corporation. A total of 12 tons of plastics & coal and 5 tons of waste rubber tire & coal were processed to produce clean light distillates (180-650{degrees}F) with less than 40 ppm of nitrogen and 20 ppm of sulfur. Coal conversion was well maintained (92 W% maf) and nearly complete conversion of the organic waste to oils was achieved (65 W%+ maf distillate yields). Both the plastics and rubber contributed hydrogen to the liquefaction thereby reducing the hydrogen consumption by as much as 2 W% of the maf feed. This has a direct impact on reducing the cost of premium fuels from coal. Co-liquefaction of waste organic materials with coals provides for the recovery and recycle of problem wastes back into the economy as premium fuels. Analyses of the process data and products collected from these operations are in progress. A concerted effort is underway to optimize the process to produce more value-added products with improved energy efficiency.
