Abstract: The invention relates to a method for carrying out the distillative separation of C5+ cuts into a low boiler fraction (A), a medium boiler fraction (B) and into a high boiler fraction (C) inside one or more partition columns (TK). A partition (T) is arranged inside said partition column(s) in a longitudinal direction of the column(s) while forming an upper common column area (1), a lower common column area (6), a feed part (2, 4) having a reinforcing part (2) and stripping part (4), as well as while forming a withdrawal part (3, 5) also having a reinforcing part (5) and stripping part (3). The inventive method involves the following steps: supplying the C5+ cuts (A, B, C) in the middle area of the feed part (2, 4); discharging the high boiler fraction (C) out of the bottom of the column; discharging the low boiler fraction (A) via the top of the column, and; discharging the middle boiler fraction (B) out of the middle area of the withdrawal part (3, 5). The dividing up ratio of the liquid reflux at the upper end of the partition (T) is set such that the proportion of high-boiling key constituents in the liquid reflux above the stripping part (3) of the withdrawal part at the upper end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B). In addition, the heating capacity in the bottom evaporator of the partition column (TK) is set such that the concentration of the light-boiling key constituents in the liquid at the lower end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B).

Abstract: Preparation of propene and optionally 1-butene comprises converting butene isomers to propene isomers using metathesis catalyst and converting formed 2-pentene to propene and 1-butene, isolating and recycling the 2-butene fraction. Preparation of propene and optionally 1-butene comprises: (a) converting 1-butene and 2-butene in the presence of a metathesis catalyst containing group VIb, VIIb or VIII metals; (b) removing propene and 2-pentene formed; (c) converting the 2-pentene using ethene to propene and 1-butene in the presence of the metathesis catalyst in (a); (d) removing propene and 1-butene formed; and (e) discharging the 1-butene and partially isomerizing 1-butene to 2-butene in the presence of a catalyst and recycling the 1-butene and 2-butene with a part of the unreacted 4C-fraction from (a) to (a). An Independent claim is also included for the apparatus for carrying out the preparation of propene and 1-butene comprising a metathesis reactor (R01) connected to a distillation column (K101) for removing 2/3C low boiling, 4C middle boiling and 5C+ high boiling phases; column (K301) for removing ethene and propene; and reactor (R02) for reacting 2-pentene with ethene.

Abstract: Column with packing is used for distillation/reactive distillation of mixture with toxic component(s). Packing layer(s) has upper and lower end, with variable internal geometry over height (H). Lower zone (6) of packing layer, with higher flow resistance, gives bubbling layer with mainly dispersed gas phase and upper zone (7) develops film flow with mainly continuous gas phase. Column with a packing is used for the distillation or reactive distillation of a mixture, with at least one toxic component. At least one packing layer has an upper and a lower end, with a variable internal geometry over its height (H). The lower zone (6) of the packing layer, with a higher flow resistance, gives a bubbling layer with a mainly dispersed gas phase and, at the same time, the upper zone (7) develops a film flow with a mainly continuous gas phase.
