Abstract: PROBLEM TO BE SOLVED: To provide a process for catalytically hydrogenating a hydrocarbon stream by which the fewest possible undesired secondary components such as oligomers and/or polymers and/or cracking products are formed. SOLUTION: The hydrocarbon stream is catalytically hydrogenated by adding a basic compound to the starting material stream without using a different solvent from the hydrocarbon stream to be hydrogenated. Thereby, the formation of undesired secondary components on the catalyst is effectively prevented. COPYRIGHT: (C)2003,JPO

Abstract: Process for producing shaped sintered parts containing finely divided carbon by shaping a mixture of a) a ceramic and/or metallic powder and b) polyoxymethylene and/or a copolymer containing a predominant proportion of oxymethylene units to give a green body, removing the binder by treatment with a gaseous acid, pyrolysis and sintering, with there being added to the mixture of a) and b) a thermoplastic c) which, at temperatures of from 90 to 220 DEG C, is molten, miscible with polyoxymethylene and stable and does not undergo a crosslinking reaction with formaldehyde, and also a composition for this process.

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).
