“…Since then, much research has been done on the topic and the positive role of a carbonaceous species was confirmed. These species can be contained in the precursor such as molybdenum naphthenate [111] or in the sulfidizing agents like DMDS. They might be introduced in the form as well of oxygenated organic admixtures [115,116] as of templating surfactants, either ionic or non-ionic [104].…”

“…Um composto chave nessa busca envolve o dissulfeto de molibdênio dopado com níquel ou cobalto e ancorado na superfície de suportes inertes [14][15][16][17] ou ainda altamente disperso no meio reacional 18,[28][29][30] . O processo envolve a remoção de poluentes de combustíveis, na presença de hidrogênio.…”

“…No caso da síntese de catalisadores dispersados no meio reacional [28][29][30] , utiliza-se a decomposição do tetratiomolibdato de amônio na presença de ácido sulfídrico e atmosfera redutora de hidrogênio [28][29][30] (eq. 2,7), sulfetação de heptamolibdato de amônio com ácido sulfídrico 29 ou reação do tiocianato de potássio com óxido de molibdênio 30 (eq.…”

“…HDS is the central process to remove sulphur from crude oils. There are several ways to prepare these catalysts, like comaceration [29], homogeneous sulphide precipitation [14], hydrothermal and solvothermal processes [30][31][32][33][34], solution reactions [35,36] and thiosalt decomposition [37][38][39]. With the decomposition of thiotungstates a high sulphur content can be achieved in the final WS 2 catalysts [40,41].…”
