What is the Yield of the Pyrolysis Plant? (Up to 80% on Dry Feed)

The yield of a pyrolysis plant can vary significantly depending on the type of pyrolysis process used and the specific conditions within the plant.

Generally, fast pyrolysis processes are designed to maximize the production of bio-oil, with yields of up to 80% on dry feed.

This yield is typically composed of 65% liquids (bio-oil), 10% non-condensable gases, and the remainder as char or other solid residues.

1. Fast Pyrolysis Yields

Bio-oil: Fast pyrolysis is optimized to produce bio-oil, which can account for 65% of the yield.

This liquid product is a valuable biofuel and chemical feedstock.

Gases: About 10% of the yield is in the form of non-condensable gases, which include components like CO, H2, CH4, CO2, and light hydrocarbons.

These gases can be used as fuel or for other chemical processes.

Char: The remaining 5% or more typically constitutes char, a solid residue that can be used as a soil amendment or fuel.

2. Process Parameters Influencing Yield

Temperature: The pyrolysis temperature significantly affects the yield.

Low temperatures (up to about 650°C) maximize the yield of condensable vapours, while high temperatures (above 700°C) increase gas yields.

Heating Rate and Residence Time: Fast pyrolysis requires very high heating rates and short residence times at the pyrolysis temperature, typically less than one second, to optimize bio-oil production.

Feedstock Characteristics: The feedstock must be dry and of small particle size (< 3 mm) to ensure efficient heat transfer and reaction.

3. Types of Pyrolysis Plants and Their Yields

Small-scale vs. Industrial-scale Plants: Small-scale plants handle lower volumes of feedstock and can be tailored to specific biomass types, potentially affecting the yield and product quality.

Industrial-scale plants, on the other hand, are designed for higher throughput and may achieve more consistent yields due to their larger scale and more controlled processes.

Batch vs. Continuous Processes: Continuous pyrolysis processes generally offer more stable product quality and potentially higher yields compared to batch processes, which can suffer from variability due to cyclic heating and cooling.

In summary, the yield of a pyrolysis plant is highly dependent on the specific process parameters and the scale of operation.

Fast pyrolysis, when properly optimized, can achieve high yields of bio-oil, making it a promising technology for renewable energy and chemical production.
