According to a preferred embodiment, the present invention features a bulk catalyst that includes precipitated cobalt metal. The precipitated cobalt catalyst further includes a textural promoter, a binder and optionally a Group I metal. The method of making the catalyst is optimized so as to enhance attrition resistance and improve activity. According to some embodiments, the present catalyst is made by a method that includes one or a combination of: calcination under optimized temperature conditions; exposure to an acidic solution; and addition of a binder to a suspension of a precipitate. According to some embodiments, a Fischer-Tropsch process includes contacting the present catalyst with a feed stream containing carbon monoxide and hydrogen so as to produce hydrocarbons.
Dans l'une de ses versions préférées, l'invention porte sur une masse catalytique comportant du cobalt métallique précipité ainsi qu'un promoteur texturé, un liant et facultativement un métal du groupe I, l'élaboration du catalyseur étant optimisée pour en favoriser la résistance à l'usure et en accroître l'activité. Dans certaines variantes, le catalyseur est obtenu par un procédé incluant une ou plusieurs des opérations suivantes: calcination dans des conditions optimales de température, exposition à une solution acide, addition d'un liant à une suspension de précipité. Dans d'autres variantes, le processus Fischer-Tropsch consiste à mettre le présent catalyseur avec un courant d'apport contenant du CO et de l'hydrogène de manière à produire des hydrocarbures.
