Coprocessing of plastics with coal and petroleum resid
- Auburn Univ., AL (United States)
Waste plastics have become an increasing problem in the United States since land filling is no longer considered a feasible disposal method. Since plastics are petroleum-derived materials, coprocessing then with coal to produce transportation fuels is a feasible alternative. In this study, catalytic coprocessing reactions were performed using Blind Canyon bituminous coal, Manji petroleum resid, and waste plastics. Model polymers including polystyrene, low density polyethylene (LDPE) and polyethylene tereplithalare (PET) were selected because they represent a substantial portion of the waste plastics generated in the United States. Coprocessing reactions of coal, resid, and polymer as well as reactions of individual components and combinations of two components were performed at 430{degrees}C for one hour with an initial H{sub 2} pressure of 8.5 MPa introduced at ambient temperature with presulfided NiMo/Al{sub 2}O{sub 3} as catalyst. Coprocessing all three materials resulted in a substantial improvement in the total conversion compared to the coal plus polymer reaction and slightly less conversion than the resid plus polymer combinations.
