Abstract: Ordered packing, for a reactor for gas phase oxidation of o-xylene and/or naphthalene with molecular oxygen to form phthalic acid anhydride, has flow channels parallel to the long axis of reactor that fills the reactor cross-section to an edge gap whereby the maximum width of the edge gap measured in the plane at right angles to the long axis of the reactor is less than the hydraulic diameter of the flow channels. An ordered packing (1), for a reactor for the gas phase oxidation of o-xylene and/or naphthalene with a molecular oxygen containing gas stream to form phthalic acid anhydride, has flow channels (2) parallel to the long axis of the reactor that fill the reactor cross-section to an edge gap (3) whereby the maximum width of the edge gap (3) measured in the plane at right angles to the long axis of the reactor is less than the hydraulic diameter of the flow channels (2), preferably less than half of the hydraulic diameter of the flow channels (2) and the packing (1) is coated with an oxidation catalyst for phthalic acid anhydride. Independent claims are included for processes for the application or coating of an oxidation catalyst onto the packing (1) by dipping or spraying a suspension containing the catalyst or catalyst precursor onto the packing (1).

Abstract: Raney alloy catalysts applied to a support are described, said catalysts having an extremely thin layer of Raney alloy with a thickness of 0.01 to 100 mum. These catalysts are prepared by vapor deposition of the appropriate metals under reduced pressure. They are generally suitable for all known hydrogenation and dehydrogenation reactions and are extremely abrasion-resistant.

Abstract: Micro-structured, self-cleaning, catalytically-active surface with peaks and hollows contains a catalytically-active material in the hollows. Independent claims are also included forthe following: (a) formed catalyst bodies with an active surface; (b) a method for the production of catalyst surfaces and formed catalysts as above by powder-coating the surface of a support with particles in the size range 0.05-200 microns and then coating with a catalytically-active material; (c) an alternative method comprises: (i) optionally coating the support with a metal primer by layer deposition; (ii) applying a first layer of metal with embedded particles (0.05-200 microns) to the surface of the support or the primer layer by deposition from a solution containing these dispersed particles and (iii) coating with a catalytically-active second layer; and (d) micro-structured, self-cleaning, catalytically-active surfaces and catalysts obtained by these methods.

Abstract: The invention relates to a method, whereby the colour number of polyhydric alcohols, in particular, trihydroxymethylpropane, can be significantly improved by hydrogenation. The method is characterized in that an alcohol is used in the hydrogenation, which has been previously purified by distillatio n. The conventional catalysts for hydrogenation are used as catalysts, preferab ly copper, nickel, palladium or ruthenium.

Abstract: The invention relates to a method for cleaning crude terephthalic acid by means of catalytic, hydrogenating aftertreatment using a catalyst material containing at least one hydrogenation metal applied to a carbon carrier consisting of carbon fibres. The invention also relates to a catalyst consisting of the at least one catalyst material containing the at least one hydrogenation metal applied to the carbon fibres, the BET surface of the carbon carrier being
