Composite Pyrolysis of Biomass and Plastic for High-quality Fuel Oil over HZSM-5

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