The study aims to convert mixed plastic waste (MPW) originating from railway stations in India into valuable fuels for domestic heating, industrial heating, and automotive sector applications. An innovative thermo-catalytic depolymerization (TCD) technology was employed to produce the fuels. The MPW was subjected to thermo-chemical degradation at an optimized temperature range of 400–450 ℃ for 5–6 hours to obtain liquid pyro-fuel, pyro-char, and flammable pyro-gas. The pyro-fuel properties were analyzed as per the ASTM standards. Notably, the properties of fuel generated from MPW represented comparable results with those of conventional petroleum fuels. The produced pyro-fuels could effectively be used in domestic heating utilities such as air-pressure stoves, domestic wick stoves, and domestic LPG stoves. The industrial gas burner was also operated with the pyro-gas. Finally, the upgraded pyro-fuel was utilized in automotive two-wheeler applications.

摘要

The study aims to convert mixed plastic waste (MPW) originating from railway stations in India into valuable fuels for domestic heating, industrial heating, and automotive sector applications. An innovative thermo-catalytic depolymerization (TCD) technology was employed to produce the fuels. The MPW was subjected to thermo-chemical degradation at an optimized temperature range of 400–450 ℃ for 5–6 hours to obtain liquid pyro-fuel, pyro-char, and flammable pyro-gas. The pyro-fuel properties were analyzed as per the ASTM standards. Notably, the properties of fuel generated from MPW represented comparable results with those of conventional petroleum fuels. The produced pyro-fuels could effectively be used in domestic heating utilities such as air-pressure stoves, domestic wick stoves, and domestic LPG stoves. The industrial gas burner was also operated with the pyro-gas. Finally, the upgraded pyro-fuel was utilized in automotive two-wheeler applications.
