Waste oil regeneration diesel equipment, commonly known as a "mixed waste oil to diesel machine," is an industrial apparatus that converts waste oils such as used engine oil, waste tire pyrolysis oil, and waste plastic oil into clean diesel through a combination of thermal cracking and catalytic distillation processes.
Core Process:
The system primarily employs an integrated process of high-temperature distillation, catalytic cracking, and fractionation refining. After pre-treatment to remove impurities and water, the waste oil is subjected to high temperatures (approximately 300-400°C) in the presence of specialized catalysts. This causes long-chain hydrocarbon molecules to crack into shorter-chain molecules within the diesel boiling range. The resulting light oil vapors are separated via a multi-stage fractionation column and then undergo refining steps such as condensation, decolorization, and deodorization. The final product is a diesel component oil that meets the standards of GB/T 20828.
Key Technical Features:
Safe and Eco-Friendly Design: A closed negative-pressure system integrated with exhaust gas purification effectively prevents harmful gas leaks.
Adaptive Catalyst Technology: Capable of processing complex mixed waste oils, improving oil yield (typically 70%-85%).
Intelligent Temperature Control System: Precisely regulates cracking temperature to avoid excessive cracking and the production of hazardous substances.
Modular Structure: Facilitates maintenance and upgrades, suitable for small to medium-scale operations (common daily processing capacity: 1-20 tons).
Market Application & Regulations:
This type of equipment must comply with the Pollution Control Standards for Recovery and Utilization of Waste Mineral Oil (GB 17145) and operate within a compliant hazardous waste disposal licensing framework. Current technological trends focus on energy consumption
optimization (waste heat recovery rates exceeding 30%) and intelligent control (automated PLC monitoring of the entire cracking process) to meet increasingly stringent environmental requirements.
