Abstract

A presente tecnologia descreve um processo de transformação do bio-óleo em nanoestruturas de carbono com propriedades ácidas, podendo ser magnéticas. Esse processo envolve a reação de sulfonação do bio-óleo em uma faixa de temperatura entre 80 e 120 °C, podendo ser impregnado com 8 a 24% de ferro, e pirolisado a 400-600 °C, o que leva à formação de nanoestruturas de carbono funcionalizadas com grupos sulfônicos ácidos, que apresentam aplicações em diversos campos da ciência, como adsorção e catálise.The present technology describes a process of transforming bio-oil into carbon nanostructures with acidic properties, which may be magnetic. This process involves the bio-oil sulfonation reaction at a temperature range between 80 and 120 °C, which can be impregnated with 8 to 24% iron, and pyrolyzed at 400-600 °C, which leads to the formation of nanostructures of carbon functionalized with acid sulfonic groups, which have applications in several fields of science, such as adsorption and catalysis.
