ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(18), P. 7170 - 7181

Published: April 21, 2023

In this study we compare techno-economics and life cycle assessment of thermochemical depolymerization technologies, including pyrolysis, gasification, hydrocracking, hydrothermal liquefaction, hydrogenolysis, to generate various products from low-density polyethylene (LDPE) waste. We elucidate the effects production scale, collection cost, concentration LDPE in plastic Pyrolysis olefins followed by their conversion lubricant oils is most profitable technology. Hydrogenolysis, producing a small fraction oils, becomes at plant sizes above 25 kt/y produces lowest CO2 emissions. Hydrocracking second environmentally friendly technology but economically competitive sufficiently large scales, supply chain for collecting plastics optimized. Gasification H2 high emissions, price ∼3 $/kg higher than current markets recently announced goals. Similarly, liquefaction also gives making carbon capture systems imperative both technologies. Our results demonstrate that lowering cost sorting waste, waste near big cities, building plants, achieving selectivity value-added are critical successful management.

Hydrogen/Syngas Production from Different Types of Waste Plastics Using a Sacrificial Tire Char Catalyst via Pyrolysis–Catalytic Steam Reforming

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(9), P. 6661 - 6673

Published: April 12, 2023

Single plastics and mixed waste from different industrial commercial sectors have been investigated in relation to the production of hydrogen syngas using a pyrolysis–catalytic steam reforming process. The catalyst used was carbonaceous char produced pyrolysis tires. Total gas yields processing single were between 36.84 39.08 wt % (based on input plastic, reacted steam, gasification) but those terms yield based only mass plastic very high. For example, for low-density polyethylene (LDPE) at temperature 1000 °C, 445.07 since both also gasification contributed yield. product largely composed H2 CO, i.e., (∼80 vol %), significantly increased as raised 900 °C. Hydrogen polyolefin ∼130 mmol gplastic–1 with tire that ranged 92.81 122.6 dependent compositional fraction individual their mixtures. process acted volatiles produce reactant ("sacrificed"), via carbon-steam further hydrogen.
