The IVIG/COPPE/UFRJ develops applied research in biomass and waste pyrolysis, focusing on the energy recovery of materials and the reduction of environmental impacts. The technology allows the conversion of residual biomass and plastic waste into products with energy and environmental value, contributing to the sustainable use of waste and the reduction of CO₂ emissions.
Waste Pyrolysis
Pyrolysis Reactor
The IVIG/COPPE/UFRJ laboratory has a pyrolysis reactor based on technologies used in BLJ-16 type systems, developed by the Chinese company Beston Group, designed for the thermochemical conversion of biomass and waste in the absence of oxygen.
The equipment allows for the processing of different materials, such as residual biomass and plastic waste, by subjecting them to controlled temperatures and transforming them into three main fractions: condensable vapors (which can originate pyrolytic oil), combustible gases, and biochar.
The generated vapors pass through a condensation system to obtain liquid fractions, while the non-condensable gases can be reused as a source of thermal energy for the process itself, increasing the system's efficiency.
The reactor is used in research focused on energy recovery from waste, circular economy, and the development of low environmental impact technologies.
Biochar
The solid fraction resulting from pyrolysis is biochar, a carbonized material rich in stable carbon. This product has several applications, such as soil conditioner, nutrient retention, and carbon storage, and can contribute to climate change mitigation strategies.
Combustible Gases
Some of the generated vapors do not condense, forming combustible gases composed mainly of hydrogen, carbon monoxide, methane, and other light hydrocarbons. These gases can be reused to generate thermal or electrical energy, contributing to the energy efficiency of the system itself.
