  • What is partial hydrogenation of vegetable oils?
  • ( Springer ) Partial hydrogenation of vegetable oils is carried out to improve the chem. stability and raise the m.p. to produce semi-solid products such as margarine. Trans fatty acids formed during traditional hydrogenation have come under intense scrutiny with regard to human health.
  • Why do we use hydrogenated fat & oil?
  • High costs of butter fat and its poor storage stability led to using hydrogenated fats and oil. The unsaturated fatty acid content of triglycerides is changed by hydrogenation into hydrogenated oils by the saturating of their carbon double bonds (C=C) and converting them to single carbon bonds (C-C) in the presence of catalyst, usually Nickel.
  • How does a hydrogenator work?
  • Hydrogenators allow the hydrogen to accumulate in the headspace above the oil with recirculation provided by vortex action of the agitator. During hydrogenation, water is circulated through the cooling coils to counteract the heat of reaction since hydrogenation is an exothermic reaction, and later for cooling prior to filtration.
  • What makes a good catalyst for edible oil hydrogenation?
  • A good catalyst for edible oil hydrogenation must have good activity, selectivity, poison resistance and filterability. The phys. characteristics of the catalyst affect these attributes greatly. This paper discusses these attributes and how a catalyst and the operating conditions affect them.
