The biomass pyrolysis fixed bed reactor is a device dedicated to the biomass pyrolysis process. It adopts a fixed bed structure and slowly pyrolyzes various types of biomass (such as wood chips, straw, rice husks, etc.) under anaerobic or anoxic conditions. The equipment precisely controls the temperature, pressure and reaction time to decompose the biomass during the pyrolysis process to produce three-phase products of liquid (bio-oil), gas (synthesis gas) and solid (biochar), thereby realizing the high-value utilization of waste biomass.

Working Principle

The core of the fixed bed reactor is a fixed reaction bed, where the biomass raw materials are uniformly loaded in the reactor with suitable particle size. Under the protection of oxygen-free or inert gas (such as nitrogen), the reactor uses electric heating, thermal oil or steam heating to heat the bed. Biomass undergoes pyrolysis under high temperature conditions, mainly undergoing the following processes:

• Pyrolysis decomposition: The organic components in the biomass decompose under high temperature to form volatile components and solid carbon.
• Gas-liquid separation: The generated volatile components are condensed into bio-oil through the cooling system, and some exist in the form of gas.
• Product collection: Through a carefully designed separation system, bio-oil, syngas and biochar are separated and collected for subsequent processing and utilization.

Main features and advantages

Simple structure and stable operation
The fixed bed structure is simple in design, and the equipment is easy to manufacture, install and maintain, suitable for small and medium-sized and pilot-scale production.

High process stability
Adopting automated control systems (such as PLC control) to achieve precise control of temperature, pressure and residence time, ensuring stable reaction process and consistent product quality.

Multiple heating methods to choose from
Electric heating, thermal oil heating or steam heating can be selected according to different process requirements, and flexibly adapt to different production scales and energy efficiency requirements.

Wide applicability
Can process a variety of biomass raw materials, including agricultural waste, forestry by-products, etc., to achieve waste resource utilization and reduce environmental pollution.

High product added value
The reactor can efficiently convert biomass, and the generated bio-oil can be further processed and upgraded to fuel oil, biodiesel, etc., and biochar can be used for soil improvement and carbon sink applications.

Scope of application
