Abstract
PROCESSO PARA OBTENçãO DE BREUS A PARTIR DE ALCATRõES E SEUS RESPECTIVOS DESTILADOS E RESPECTIVO USO DOS MESMOS NAS APLICAçõES PRóPRIAS DOS PRECURSORES CARBÈNICOS. A invenção refere-se à produção de breus destinados a aplicações múltiplas a partir de destilados procedentes do alcatrão de hulha de alta temperatura com uma faixa de destilação superior a 260°C, mediante a aplicação seqüencial e combinada de três etapas em condições suave de pressão e temperatura(<400°C, < 10 bar g): tratamento térmico oxidante utilizado como reagente ar e oxigênio, suas misturas, o ar empobrecido em oxigênio; tratamento térmico sob atmosfera inerte, e destilação fracionada. Como resultado obtém breus que apresentam vantagens para o meio ambiente e de saúde laboraral, utilizáveis como precursores carbónicos.
