Abstract

"PROCESSO PARA HIDROGENAçãO CONTìNUA". A presente invenção refere-se a hidrogenação contínua de uma solução de trabalho contendo um composto hidrogenável com hidrogênio na presença de um catalisador heterogêneo, onde pelo menos parte do gás residual de hidrogenação contendo hidrogênio é reciclado no reator de hidrogenação após a compressão. De acordo com a invenção, é usada uma bomba de jato para a compressão do gás residual de hidrogenação e uma matéria-prima gasosa ou líquida do processo de hidrogenação é usada como agente motriz. Os agentes motrizes preferidos são o gás de hidrogenação ou uma solução de trabalho reciclada no processo. O processo é particularmente adequado para efetuar a etapa de hidrogenação no processo de antraquinona para a produção de peróxido de hidrogênio.
