Generally, the recovery rates for different components from used tires by pyrolysis are approximately as follows:

• Pyrolysis Oil: The oil yield from used tires is typically in the range of 35% to 50% by weight. This pyrolysis oil is a complex mixture of hydrocarbons derived from the decomposition of the rubber components in the tires.
• Pyrolysis Gas: The gas yield is around 10% to 15% by weight. This gas consists of various hydrocarbons and can be used as a source of energy.
• Carbon Black: The yield of carbon black, a solid residue, is approximately 20% to 35% by weight. Carbon black is often used as a reinforcing agent in rubber products or as a pigment in various applications.
• Steel Wire: The steel wire in tires, used as reinforcement, can be recovered and constitutes around 10% to 15% by weight.

It’s important to note that these percentages are general estimates, and the actual recovery rates can vary based on the specific conditions of the pyrolysis process and the type of tire feedstock.

Generally, the recovery rates for different components from waste plastic by pyrolysis are approximately as follows:

• Pyrolysis Oil: The oil yield from waste plastic is typically in the range of 30% to 70% by weight. The composition of the pyrolysis oil can vary, and it is a mixture of hydrocarbons derived from the thermal decomposition of the plastic.
• Pyrolysis Gas: The gas yield is usually around 10% to 20% by weight. This gas can be utilized as a source of energy.
• Carbon Black: The yield of carbon black, a solid residue, is approximately 10% to 30% by weight. Carbon black can have various applications, including as a reinforcing agent in rubber products or as a pigment.
• Residue or Char: The remaining solid residue after pyrolysis, sometimes referred to as char or ash, constitutes a portion of the original plastic mass. The percentage of residue depends on the efficiency of the pyrolysis process.

Oil sludge typically consists of a mixture of water, oil, and solid particles, often generated as a byproduct of oil refining, drilling, or other petroleum industry processes.

The recovery rate of oil from oil sludge by pyrolysis is generally in the range of 40% to 70%. This means that a significant portion of the oil content in the sludge can be converted into pyrolysis oil during the thermal decomposition process. The remaining components may include water, solids, and gases.

Several factors influence the recovery rate:

• Pyrolysis Conditions: The temperature, pressure, and residence time in the pyrolysis reactor are critical factors that affect the efficiency of the process and the yield of pyrolysis products, including oil.

• Oil Sludge Composition: The specific composition of the oil sludge, including the types of hydrocarbons present, the water content, and the presence of contaminants, can influence the pyrolysis process and the recovery of oil.

• Pyrolysis Technology: Different pyrolysis technologies and reactor designs can have varying efficiencies and yields. Advanced pyrolysis technologies may offer better recovery rates and product quality.

• Pre-treatment: Pre-treatment steps, such as dewatering or separating solid contaminants, can impact the overall recovery rate by improving the feedstock quality before pyrolysis.
