Abstract: The invention relates to moderately twisted polylobed extrudates having improved crush strength. The moderately twisted polylobed extrudates have an oblong shape and a cross section comprising a plurality of lobes, which lobes extend along and are twisted around a longitudinal axis of the extrudate and wherein the twist has a pitch from about 0.5 turns/inch (0.5 turns per 2.54 cm) to about 2 turns/inch (2 turns per 2.54 cm). Further the invention relates to a method for manufacturing such moderately twisted polylobed extrudates and their use as catalysts or adsorbents.

Abstract: A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising nebulizing a liquid containing a noble metal and a chelating agent comprising at least one nitrogen-containing functional group to form a nebulized liquid, and contacting the nebulized liquid with silica particles; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.
