I need a comprehensive explanation of vegetable oil hydrogenation reaction kinetics?

Please, provide sketches, diagrams, pictures and as high level of chemistry as possible. State the consumption of catalysator and the consumption of hydrogen per 1 kg of oil to be transformed to fat.I need a comprehensive explanation of vegetable oil hydrogenation reaction kinetics?
Well, the kinetics are actually pretty complicated.





All of the catalysts I'm aware of for this type of reaction are heterogeneous. This complicates things for several reasons. First, the rate is going to be much more dependent on reactor design since how well the catalyst is suspended and dispersed plays a big role in the rate of reaction. Second, the rate will depend on the active surface area of the catalyst, which can vary from batch to batch of catalyst and must be determined empirically for each sample.





Another tricky issue is that in the course of the reaction you are going from a liquid (oil) to solid (fat). This will change the physical properties of your mixture, which changes the way the catalysts is distributed and will certainly change the kinetics. Solution viscosity could potentially become an issue, especially on the industrial scale. It really just depends on how you run the reaction.





In terms of amount of H2 needed, it's going to depend on precisely what kind of oil you are starting with. Most vegetable oils are mixtures of several oils made of the triacylgylcerides of unsaturated fatty acids such as oleic acid and linoleic acid. Since the degree of unsaturation varies from acid to acid (and therefore oil to oil), it depends entirely on which specific oil you have.





In terms of catalyst, in principle it's always regenerated and never lost.





I wish I could give you more specifics, but the kinetics here are really messy and not easily amenable to a traditional analysis.
