Abstract

"PROCESSO PARA A PRODUçãO DE UM MATERIAL BASE LUBRIFICANTE ISOPARAFìNICO". Material base lubrificante com elevado VI e baixo ponto de gota é produzido por hidroisomerização de uma fração cerosa de hidrocarbonetos sintetizados por Fischer-Tropsch, parafínicos, de elevada pureza, que possuem um ponto de ebulição inicial na faixa de 343-399°C, seguido de um remoção catalítica da cera do hidroisomerizado usando um catalisador para remoção de cera que compreende um componente catalítico de platina e um componente mordenita-H. A fração de hidrocarbonetos é sintetizada de preferência por Fischer-Tropsch em suspensão, usando um catalisador contendo um componente catalítico de cobalto. Essa combinação de processo, elevada pureza, alimentação parafínica cerosa e catalisador para remoção de cera de mordenita-H/Pt, produz uma produção relativamente elevada de material base lubrificante de boa qualidade.
