Torrefaction and pyrolysis of metal-enriched poplars from phytotechnologies: Effect of temperature and biomass chlorine content on metal distribution…
2017
Abstract Torrefaction (290 °C) and pyrolysis (450 and 800 °C) trials were performed at pilot scale with a patented reactor on metal-enriched poplars from a contaminated soil managed by phytotechnologies and poplars cultivated on uncontaminated soil, for comparison. This study emphasized the influence of temperature on end-product yield, metal distribution in end-products and metal behavior. Results showed that the evolution of the end-product yield, i.e. biochar, bio-oil and gas fractions, was depending on temperature rather than other parameters such as the origin or metal content of the tested poplars. Torrefaction decreased the processed poplars weight, leading to metal-enriched torrefie…
Emissions from metallic powder and high energy-based process - thermal spraying knowledge refresh
2021
International audience; Recently, in different industrials sectors, emissions are subjected to rules and regulations which are coming increasingly stringent and more carefully monitored. And this is where thermal spraying, powder atomization and additive manufacturing come in metal powder and high energy-based processes. These technologies manufacture or use micrometer size feedstock. But the process characteristics as the heat source induces nanoparticle formation. The paper is to address a knowledge refresh on thermal spraying regarding emissions due to the process in relationship with working conditions, personal protection, dust filtration, etc. A survey has been conducted and the resul…
