Abstract: PROBLEM TO BE SOLVED: To provide a distillation column having high separation efficiency, in which the vapor amount is made constant all over the column including a feed section and a side steam take-off section.
SOLUTION: Partition walls DW are arranged substantially along the longitudinal direction of the distillation column so that the inside of the distillation column is divided into an upper zone 2 and a lower zone 4 of the feed section, an upper zone 3 and a lower zone 5 of the side stream take-off section, an upper common column section 1 and a lower common column section 6. A feeding mixture to be separated between the zones 2 and 4 of the feed section is in a wholly or partially vaporized state and/or the side stream to be taken off from the zones 3 and 5 of the side stream take-off section is in a wholly or partially vaporized state.

Abstract: A continuous process for the production of sugar alcohols by catalytic hydrogenation of an aqueous solution of a saccharide in the presence of a ruthenium catalyst prepared by treatment of an amorphous silicon dioxide based support material with a halogen-free aqueous solution of a low mol. wt. ruthenium compound followed by drying of the treated support at below 200 [deg]C and reduction of the resulting solid with hydrogen at 100-350 [deg]C.

Abstract: Distillation column has a dividing wall which divides it into inflow and extraction sections, and upper and lower column zones. The mixture for distillation comprises a vapor feed which enters between the upper and lower inflow sections, between which the side extraction point removes vapor. The inflow and the extraction zones are offset relative too the dividing wall. The vapor feed rate is equal in all zones of the column. The distillation column has a dividing wall (TW) which divides it into an inflow section (2,4), an extraction section (3,5), and common upper (1) and lower (6) column zones. The mixture for distillation is at least partially a vapor feed (F) which enters between the upper and lower inflow sections, and the side extraction point (B) removes vapor between the upper and lower extraction zones. The cross sectional surfaces of the inflow and the extraction zones are set by an offset in the dividing wall. The F-factor is equal in all the zones of the column, defined as the product of the gas flow speed in m/seconds multiplied with the square root of the gas density in kg/m3.
