Abstract

Catalytic co-pyrolysis of biomass and plastic is a promising technology to their resource recovery and energy conversion. For the traditional technologies, the two feedstocks are mechanically mixed (MM) to the co-conversion reaction. However, there are disadvantages in the MM mode process, such as mixing nonuniformity and inconvenient transportation of feedstocks, poor heat and mass transfer during pyrolysis and low yield of effective products. To solve the above issues, a composite pyrolysis of biomass and plastic for high-quality fuel oil was innovatively studied in this paper at a lab-scale fixed bed reactor using HZSM-5 as a catalyst. Through procedures including mechanical mixing, hot pressing and crushing granulation, a composite molding (CM) sample was prepared. Then the optimal conditions for fuel oil production of the CM sample were explored, and under which conditions products distribution were compared with pyrolysis from the common MM sample. And possible mechanism for high-quality fuel oil generation of the composite pyrolysis was put forward through characterization of sample properties. Results show that, under the optimal reaction conditions of the composite pyrolysis, the yield of fuel oil was increased by 34.8% and the yield of aromatics was increased by 50.7% compared with the conventional pyrolysis from MM sample. Advantages of the composite pyrolysis could be explained by the enhanced contact between biomass and plastic particles, which promoted a stronger synergy between the two derived intermediates and effectively improved mass and heat transfer during pyrolysis process.
