Abstract: A catalyst packing which can be produced by vapor deposition and/or sputtering of at least one substance active as catalyst and/or promotor onto woven or knitted fabrics or sheets as support material is used in a process for catalytic distillation in which a heterogeneously catalyzed reaction is combined with a simultaneous distillation or rectification over the catalyst packing.

Abstract: The invention relates to a method for recovering crude 1,3-butadiene by extractive distillation from a C4 cut, using a selective solvent in a separation column (TK). In said column, a partition wall (T) is located in the longitudinal direction of the column, forming a first sub-section (A), a second sub-section (B) and a lower common column zone (C). An extractive scrubber column (K) is connected upstream of the separation column.

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: A process is proposed for the separation of C 5+ cuts by distillation into a low-boiler (A), a medium-boiler (B) and a high-boiler fraction (C) in one or more dividing-wall columns (TK), in which a dividing wall (T) is arranged in the longitudinal direction of the column with formation of an upper, common column region ( 1 ), a lower, common column region ( 6 ), a feed part ( 2, 4 ) with rectifying section ( 2 ) and stripping section ( 4 ), and a withdrawal part ( 3, 5 ) with rectifying section ( 5 ) and stripping section ( 3 ), with feed of the C 5+ cut (A, B, C) into the central region of the feed part ( 2, 4 ), discharge of the high-boiler fraction (C) from the bottom of the column, discharge of the low-boiler fraction (A) via the top of the column, and discharge of the medium-boiler fraction (B) from the central region of the withdrawal part ( 3, 5 ), wherein the dividing ratio of the liquid reflux at the upper end of the dividing wall (T) is set in such a way that the proportion of high-boiling key components in the liquid reflux over the stripping section ( 3 ) of the withdrawal part at the upper end of the dividing wall (T) is from 10 to 80%, preferably from 30 to 50%, of the limit value allowed in the medium-boiler fraction (B), and wherein the heating power in the evaporator at the bottom of the dividing-wall column (TK) is set in such a way that the concentration of the low-boiling key components in the liquid at the lower end of the dividing wall (T) is from 10 to 80%, preferably from 30 to 50%, of the limit value allowed in the medium-boiler fraction (B).

Abstract: The invention relates to a method for treating a C4 fraction, comprising the following steps: extractive distillation (I), selective hydrogenation on a heterogeneous catalyst (II), a stream of crude 1,3-butadiene resulting from steps (I) and (II); and distillation of said stream of crude 1,3-butadiene i n order to obtain pure 1,3-butadiene (III). Steps I and II take place in a single column or in thermally coupled columns and step III is carried out in a second column.
