DOING® Plastic-to-Diesel Machine Introduction

Henan DOING® Company' s plastic-to-diesel machine is a environmentally friendly solution that converts waste plastics into high-quality diesel. This equipment employs a two-step process—pyrolysis and distillation—to transform non-recyclable plastic waste into valuable fuels, addressing both plastic pollution and generating revenue.

DOING's plastic-to-diesel machine utilizes a proven and reliable two-step process comprising two integrated production lines: a waste plastic pyrolysis unit and a waste oil distillation unit. This unit breaks down plastics at the molecular level, converting them into usable fuels

Recycling process from waste plastics to diesel fuel

Pyrolysis Stage: Waste plastics are fed into a sealed pyrolysis reactor and heated to 300-450°C in an anaerobic environment. DOING plastic pyrolysis equipment can recycle any plastic except PVC and PET. Pyrolysis involves the thermal decomposition of long-chain hydrocarbon polymers into smaller molecules, producing pyrolysis oil, carbon black, and combustible fuel. DOING' s pyrolysis reactors feature unique elliptical sealing heads at both ends, allowing for complete coverage by the external insulation layer. This minimizes heat loss during feeding—crucial because soft plastics such as PE and PP shrink upon heating, requiring continuous feeding for efficiency. Compared to standard designs, this design reduces energy consumption by up to 20% and increases oil production.

Distillation Stage: The crude plastic pyrolysis oil is then processed in a pyrolysis oil distillation unit through heating, fractionation, catalysis, decolorization, deodorization, and impurity removal. The oil is ultimately refined into pure diesel (suitable for trucks, generators, ships, and heavy machinery). The final product meets international standards, with extremely low sulfur content and odor.

Key Advantages of DOING® Plastic to Diesel Processing Machines

DOING's plastic to diesel machines are designed with reliability, efficiency, and scalability in mind, giving them a competitive edge.

1. High Efficiency and High Yield: The conversion rate of pyrolysis oil to diesel distillation machine is as high as 85-90%, and the overall conversion rate of plastic to diesel fuels is 30-70%.

2. Energy-efficient design:The recycling of Syngas generated from plastic to diesel pyrolysis distillaton process provides free heating, thereby reducing operating costs.

3. Environmentally friendly and safe: Equipped with exhaust gas treatment, wastewater recycling, and zero-emission filters, meeting global standards (e.g., EU emission standards). Promotes a circular economy by reducing plastic waste landfills.
