VERFAHREN ZUR KONTINUIERLICHEN HETEROGENKATALYTISCHEN HYDRIERUNG VON FETTEN, FETTSAEUREN UND FETTSAEUREDERIVATEN.

摘要

Continuous hydrogenation of fats, fatty acids and/or fattly acid derivs is effected by suspending a small amt. of supported transition metal catalyst in the liq. feed and passing it through a packed column reactor in co- or countercurrent with H2 at 60-260 deg. C and 0.5-300 bar. The reactor has a length/dia. ratio of at least 10 and has a geometrically regular packing of inert material. The gas velocity is 0.5-30 cm/sec, based on the total crosssection of the reactor. The reactor is pref. packed with ceramic, metal or esp. glass spheres with a dia. of 1-10 (esp.3-6) mm. The H2 is passed cocurrently at a gas velocity of 5-20 cm/sec. The catalyst comprises Ni on Na aluminosilicate and is added to the feed as a suspension in hardened fat.
