Gliceroquímica: uma rota alternativa e eficiente para obtenção de novos produtos a partir do glicerol de produção do biodiesel

Abstract

Glycerol is the main co-product of biodiesel and with the increase in biodiesel production to 13% in 2021, thanks to the measure provided for in Resolution 16, of 2018, of the National Energy Policy Council (CNPE), which authorizes the National Agency of Oil, Natural Gas and Biofuels (ANP) to increase this percentage to 15% in 2023, there was a significant increase in its production. Thus, with the excess of glycerol in the market, thanks to the transesterification process for the production of biodiesel, new technological routes will be needed to sell this product. Therefore, glycerochemistry with its various ways to increase the added value of raw glycerol will be presented throughout the work, as purified glycerol is widely used in the market, with several studies of treated transformations, but it has a costly treatment cost. for industries. Despite several studies that have been and are still being conducted on glycerol, which have several advantages for its physical-compound properties and for being a raw material of renewable origin, there is still a need for greater investments in research in the field of glycerochemistry.
