2149248 9411472 PCTABS00032 A procedure and equipement for hydrogenating oil, fat or fatty acids by adding hydrogen and using a catalyst. The procedure consists in a semi-continuous or continuous process in which the catalyst is mixed with preheated fat or oil in a mixing device (9/10, 24), the mixture is fed through a preferably serpentine-like, vertically-mounted pipe loop or one or more static mixers (11, 28) while hydrogen and, possibly, an inert gas is/are added so that a turbulent co-current is achieved, the mixture is cooled during the hydrogenation and, possibly, the oil, the catalyst, the inert gas and excess hydrogen gas are recirculated after the hardening process. The equipment comprises feed and mixing devices (A) for feeding and mixing oil and a catalyst, a preferably serpentine-like, vertically-mounted pipe loop or one or more static mixers and cooling devices with feed devices for the hydrogen gas and any inert gas (B), as well as devices (C) for collecting the oil, separating and recirculating any inert gas and feeding, separating and, possibly, recirculating used hydrogen gas, as well as separation and recirculation of the catalyst.
