Abstract
"PROCESSO PARA A HIDROGENAçãO SELETIVA DE FENILACETILENO". A presente invenção refere-se a um processo para a redução de um contaminante de fenilacetileno, na presença de um monómero de estireno. Uma corrente de monómero de estireno, contendo uma pequena quantidade de fenilacetileno, é suprida a um reator de hidrogenação. Um gás de hidrogenação, compreendendo hidrogênio, é também suprido ao reator de hidrogenação. A corrente de monómero de estireno e o hidrogênio são postos em contato com um leito de catalisador, contendo um catalisador compreendendo um composto de cobre reduzido em um suporte de alumina teta. O reator de hidrogenação é operado a uma temperatura de pelo menos 60<198>C e a uma pressão de pelo menos 206,8 kPa (30 psig), para hidrogenar fenilacetileno a estireno. Um produto é recuperado do reator de hidrogenação, tendo um teor de fenilacetileno substancialmente reduzido e um teor de estireno aumentado. O gás de hidrogenação compreende uma mistura de nitrogênio e hidrogênio.
