PROCESSOS PARA A REMOÇÃO DE COMPOSTOS DE ENXOFRE CONTAMINANTES, MAIS PARTICULARMENTE, COMPOSTOS DE ENXOFRE TIOFÊNICOS, DE CARGAS DE ALIMENTAÇÃO DE HIDROCARBONETO E PARA A PREPARAÇÃO DE UM ADSORVENTE DE NÍQUEL, E, ADSORVENTE DE NÍQUEL

摘要

The invention is directed to a process for the removal of contaminating sulfur compounds, more in particular thiophenic sulfur compounds, from hydrocarbon feedstocks, said process comprising contacting the feedstock in the presence of hydrogen with a sulfided nickel adsorbent, of which adsorbent the rate constant for tetralin hydrogenation activity at 150°C is less than 0.01 1/s.g cat and wherein in said adsorbent part of the nickel is present in the metallic form.
