Abstract
''PROCESSO PARA PRODUZIR UMA MATéRIA-PRIMA DE BASE DE LUBRIFICANTE ISOPARAFìNICO, E, LUBRIFICANTE''. Uma matéria-prima de base de lubrificante útil para formar lubrificantes tais como óleos automotivos de graus múltiplos, óleos de transmissão automática, graxas e outros é preparada hidroisomerizando-se uma fração de alimentação de hidrocarboneto ceroso tendo um ponto de ebulição inicial na faixa de 343 a 399°C e um ponto final de pelo menos 566°C, sintetizada por um processo de síntese de hidrocarboneto de Fischer-Tropsch pastoso. A hidroisomerização forma um hidroisomerizado contendo a matéria-prima de base desejada que é restabelecida, sem desencerar o hidroisomerizado. A hidroisomerização é conduzida em condições eficazes para converter pelo menos 67% em peso dos hidrocarbonetos de alimentação cerosa de 343 a 399°C+ para hidrocarbonetos de ebulição inferior. Quando combinados com um volume de aditivo de lubrificantes padrão, estas matérias-primas de base foram formadas em óleos de cárter automotivo de grau múltiplo, óleos de transmissão e óleos hidráulicos alcançando as especificações para estes óleos.'' PROCESS TO PRODUCE A RAW MATERIAL BASED ON ISOPARAPHYNIC LUBRICANT, AND LUBRICANT ''. A lubricant-based raw material useful for forming lubricants such as multi-degree automotive oils, automatic transmission oils, greases and others is prepared by hydroisomerizing a waxy hydrocarbon feed fraction having an initial boiling point in the range of 343 at 399 ° C and an end point of at least 566 ° C, synthesized by a pasty Fischer-Tropsch hydrocarbon synthesis process. The hydroisomerization forms a hydroisomerized containing the desired base raw material that is restored, without dismantling the hydroisomerized. Hydroisomerization is carried out under conditions effective to convert at least 67% by weight of waxy hydrocarbons from 343 to 399 ° C + to lower boiling hydrocarbons. When combined with a standard lubricant additive volume, these basic raw materials were formed in multiple grade automotive crankcase oils, transmission oils and hydraulic oils meeting the specifications for these oils.
