How To Produce A Potential High Value Bio-Char From The Worst Invasive Plant In Canada, Chiara Barbiero, Franco Berruti, Cedric Briens

Biochar: Production, Characterization and Applications

Phragmites Australis is a perennial plant, native to Eurasia, which is spreading worldwide, increasing fire hazards, and causing damage to wildlife and its surrounding habitat. Phragmites is classified as Canada’s worst invasive plant due to the difficulty of achieving its full eradication. Phragmites plants are fast growing and can spread quickly through seeds or rhizomes. They must be processed locally to destroy seeds and rhizomes. For these reasons, mobile pyrolysis was selected as a destruction method that provides valuable bio-char. The aim of this work is to study the effect of different pre-treatment and post-treatment strategies on bio-char characteristics, such …

Biochar: Production, Characterization and Applications

Agricultural production must be directed towards "sustainable agriculture", which preserves natural resources, reduces GHG emissions and maintains biodiversity. In this context, biochar is considered a product of great interest in agriculture since several studies have demonstrated its effectiveness in increasing agricultural yields, increasing the water retention capacity and nutrients in the soil, increasing the development of arbuscular mycorrhizal fungus (AMF), and ultimately improving the efficiency of fertilizers, thus reducing their use and reducing enviromental pollution.

Integrating Batch Pyrolysis And Fractional Condensation (2d Mfr) To Get High-Value Products From Biomass, Mohammad Hossain, Chiara Barbiero, Ian Scott, Franco Berruti, Cedric Briens

5th International Congress on Green Process Engineering (GPE 2016)

Agricultural crop residues are a source of inexpensive biomass to convert into bioproducts. The recovery of valuable chemicals from plant waste would partly solve the disposal issue and offer a more environmentally friendly alternative to synthetic chemical production. One approach to separate and concentrate valuable chemicals from biomass is pyrolysis using a batch reactor process. A mechanically fluidized reactor (MFR) was developed to pyrolyze biomass from ambient to temperatures near 600 °C, forming gases that are then condensed in an ice-chilled condenser to form a bio-oil. The bio-oil produced by the MFR can be separated within temperature ranges, termed one-dimensional …

Using The Jiggled Bed Reactor To Develop Activated Carbons From Biomass Residues, Anastasia Colomba, Franco Berruti, Cedric Briens

5th International Congress on Green Process Engineering (GPE 2016)

Activated carbons are the most used adsorbent material. Their applications range from wastewater treatment, air purification, removal of contaminants and many others. According to “Global Activated Carbon Market Forecast & Opportunities 2017”, the demand for activated carbon is expected to increase more than 10% per year for the next 5 years to make it a $3 billion market by 2017. Current processes for the production of activated carbons from renewable resources do not provide valuable co-products. This presentation focuses on the conversion to activated carbon of the bio-char co-product of the pyrolysis process. Pyrolysis also provides valuable bio-oil, which is …
