Abstract: A column separates a mixture of three or more substances. It has an outer case (1) with a cap (5) and an inner chamber with a number of longitudinal sub-chambers (3,4), each open on one side to the main chamber. One sub-chamber (3) operates as a mixture inlet chamber. Sub-chambers (3,4) feed a unification chamber (8). Especially the feed to the inlet chamber (3) is separated by gap from the chamber open end. and that the inlet zone is fabricated as a strengthened column and the other side is fabricated as column stripper (3b). The concentric sub-chambers (3,4) are separated by a segmented curved panel (2) and are joined on one side to the inner face of the case (1). The inlet chamber (3) and unification chamber (8) are linked by a pipe, throttle and gas passage for the exchange of gaseous and/or liquid phases. The column is suspended from the column cap (5). The chambers (3,4,8) are packed as appropriate with solid material and catalytic bulk grains.

Abstract: Providing a ruthenium catalyst for the production of sugar alcohols. Ruthenium catalysts (I) are prepared by: (A) a single or multiple treatment of an amorphous silicon dioxide support material with a halogen free solution of a low mol. wt. ruthenium compound followed by drying at below 200 [deg]C; (B) reduction of the resulting solid with hydrogen at 100-350 [deg]C such that step (B) is carried out immediately after step (A). An independent claim is included for a process for the production of sugar alcohols by catalytic hydrogenation of the corresponding mono- and oligosaccharides in the liquid phase at the heterogeneous catalyst (I), excluding a process for the production of sorbitol.

Abstract: Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 carbon (C) atoms comprises using a monolithic supported palladium catalyst and hydrogen containing 10-2000 ppm carbon monoxide (CO). Production of alkenes by liquid-phase hydrogenation of alkynes containing 10-30 C atoms at 20-250 degrees C and a hydrogen partial pressure of 0.3-200 bar comprises: (a) using a fixed bed of a catalyst prepared by calcining a support material in air, cooling it, impregnating it with a solution containing a palladium salt and optionally other metal ions, drying the product and shaping it into a monolithic catalyst element; and (b) either adding 10-2000 ppm CO to the hydrogen or generating an equivalent amount of CO by adding a CO-releasing compound to the liquid phase.

Abstract: The invention relates to double metal cyanide catalysts (DMC) which are applied to solid, inert non-foamed supports, introduced into the same or shaped into forms. The invention also relates to the production of said double metal cyanide catalysts and to their use for producing polyether alcohols with a low unsaturated compound content by means of catalytic ring-opening polymerisation of alkylene oxides. The DMC can be e.g., zinc hexacyanocobaltate.
