Pyrolysis research at new IVIG site at UFRJ
Researchers at the Federal University of Rio de Janeiro (UFRJ) have developed a new site for pyrolysis processes aimed at producing biochar. This advancement in biochar production is important for carbon sequestration and soil enhancement, contributing to sustainable agricultural practices.
The IVIG/COPPE/UFRJ is advancing research in biomass and waste pyrolysis, emphasizing the conversion of materials into energy and reducing environmental impacts. This technology transforms residual biomass and plastic waste into valuable energy products, aiding in sustainable waste management and reducing CO₂ emissions.
The laboratory at IVIG/COPPE/UFRJ utilizes a pyrolysis reactor based on BLJ-16 systems from the Beston Group, a Chinese company. This reactor facilitates the thermochemical conversion of biomass and waste without oxygen.
The reactor processes various materials, including residual biomass and plastic waste, by applying controlled temperatures. This process yields three main fractions: condensable vapors, which can produce pyrolytic oil, combustible gases, and biochar.
Vapors generated are condensed to obtain liquid fractions, while non-condensable gases are reused as thermal energy, enhancing system efficiency.
Research using the reactor focuses on energy recovery, circular economy, and developing technologies with low environmental impact.
The condensation of vapors results in pyrolytic oil, usable as industrial fuel or a raw material for chemical and liquid fuel production after refinement.
The solid fraction from pyrolysis is biochar, a carbon-rich material. Biochar serves as a soil conditioner, aids in nutrient retention, and stores carbon, supporting climate change mitigation.
Non-condensed vapors form combustible gases, primarily hydrogen, carbon monoxide, methane, and other hydrocarbons. These gases can be reused for thermal or electrical energy generation, improving system energy efficiency.
