Date:23 April 2024

Country: Brazil

Application

• The potential of colored cotton waste for bioenergy production through pyrolysis, yielding bio-oil with valuable organic compounds such as aldehydes, ketones, and phenols. These products can be used for biofuel generation and the production of chemicals of industrial interest. The study also underscores the environmental benefits of utilizing this biomass, promoting sustainability by reducing waste and contributing to a more sustainable energy matrix.

Description

This project evaluates the energetic potential of colored cotton waste by analyzing stalks and bolls for their chemical composition and thermal properties. The biomass was tested for heating value, moisture, volatile content, and ash through proximate and ultimate analysis. Pyrolysis was conducted to identify chemical products, revealing compounds like aldehydes, ketones, and phenols. Results show that these cotton wastes have high energy potential, with higher heating values ranging from 16.2 to 18.9 MJ/kg, making them viable for bioenergy production and chemical applications.

Pathway Description:

The process used in the study is pyrolysis, where cotton waste (stalks and bolls) is heated at 500°C in an inert atmosphere to produce volatile compounds. These products are analyzed using GC-MS to identify organic chemicals.
