Abstract
"PROCESSO DE FRACIONAMENTO DO ALCATRãO VEGETAL". Refere-se o presente pedido ao processamento do alcatrão vegetal via processos físico-químicos de separação (2) (3) e (6), de modo a se obter uma fração aquosa (4), frações de óleo de alcatrão ou óleo bruto de alcatrão (7) e piche (8). Estes sub-produtos do alcatrão vegetal constituem as matérias-primas para a obtenção de produtos de química fina que estão presentes no óleo de alcatrão e de materiais poliméricos diversos que podem ser produzidos a partir do piche de alcatrão vegetal. Deste modo, tem-se a valorização da matéria-prima alcatrão vegetal, que quando não recuperada, constitui em poluição atmosférica resultante dos processos de carvoejamento."PROCESS OF FRACTIONATION OF PLANT VEGETABLE". This request refers to the processing of vegetable tar via physical-chemical separation processes (2) (3) and (6), in order to obtain an aqueous fraction (4), fractions of tar oil or crude oil from tar (7) and tar (8). These by-products of vegetable tar are the raw materials for obtaining fine chemical products that are present in tar oil and various polymeric materials that can be produced from vegetable tar pitch. In this way, there is the valorization of the raw material vegetable tar, which when not recovered, constitutes air pollution resulting from the charcoal production processes.
