production processes of carbon nanostructures with acidic and magnetic properties, from bio-oil, products and use

摘要

The present technology describes a process for transforming bio-oil into carbon nanostructures with acidic properties, which may be magnetic. This process involves the sulfonation reaction of the bio-oil in a temperature range between 80 and 120 ° C, which can be impregnated with 8 to 24% iron, and pyrolysed at 400-600 ° C, which leads to the formation of nanostructures of carbon functionalized with acidic sulfonic groups, which have applications in several fields of science, such as adsorption and catalysis.
