Can Tire Pyrolysis Oil Be Used In Diesel Generators?

Tire pyrolysis oil is a liquid product obtained through pyrolysis technology — can be utilized in industrial kilns and boilers: in industrial facilities requiring high-calorific-value fuels — such as cement plants, steel mills, and power stations — it can serve as a direct or partial substitute for heavy oil, coal, and similar fuels to provide thermal energy. Beyond these applications, some customers are exploring further applications for tyre pyrolysis oil. One popular demand is whether it can be used in diesel generators.

The Feasibility of Using TPO in Diesel Generators

So, can tire pyrolysis oil be used in diesel generators? The answer is a resounding yes. However, since tire pyrolysis oil is not standard diesel fuel — and naturally contains certain acidic, corrosive elements as well as some colloidal impurities — it requires a distillation and refining process to be optimally suited for use in diesel generators.

DOING Advanced Tire Oil Distillation and Refining Process

To achieve this transformation into a more valuable, non-standard diesel fuel, Henan Doing Company's tire oil distillation equipment employs a sophisticated multi-stage processing workflow.This pyrolysis oil to diesel refining process includes distillation, catalytic reaction, decolorization, and deodorization.

Operational Process of Tire Pyrolysis Oil Distillation and Refining Equipment

1. Core Distillation for Vaporization and Initial Separation:

Our dual-heating system uses circulating thermal oil for preheating (up to 250°C) and direct fuel combustion to reach 290–380°C. This vaporizes the oil into gas, with uniform heating that cuts fuel costs. DOING's vertical reactor auto-discharges asphalt residue, minimizing cleaning and extending equipment life. A shell-and-tube condenser ensures >85% oil yield.

2. Advanced Catalysis for Purity Enhancement:

Henan DOING Company provides advanced catalytic pyrolysis oil refining technology where in the oil gas passes through a catalytic tower and reacts with a catalyst. Through this chemical reaction, the system further adsorbs and removes colloidal impurities, waxy substances, and pigments present in the oil gas. Following this step, the gaseous oil molecules become significantly purer, effectively preventing the finished oil from darkening or developing an unpleasant odor due to oxidation during storage. Our company can customize the equipment configuration to meet your specific requirements; we offer the option of using acid-base washing reagents or our patented solid catalyst (which generates no waste acid, waste alkali, or waste gas, and can be used continuously for up to six months before requiring replacement).

3. Decolorization and Fine Filtration for Optimal Quality:

A decolorization process using white clay is performed to enhance the clarity and quality of the oil. Finally, a purification filtration step is conducted using a plate-and-frame filter press or a precision filter to remove residual adsorbents, yielding the final product — either diesel fuel or base oil.

4. Environmental Management: Tail Gas Treatment and Residue Discharge

The heavy components remaining after distillation are discharged as asphalt residue. Non-condensable combustible gases undergo purification treatment and are typically recirculated to the heating furnace for combustion, thereby achieving energy recycling.

Through these pyrolysis oil distillation and refining processes, we produce refined, non-standard diesel fuel that can be used directly in diesel generators. Besides the diesel generators, the non-standard diesel fuel extracted from tyre pyrolysis oil also can be applied in heating boilers, furnaces, heavy machineries, ships and even trucks.
