HydrogenationAddition of hydrogen molecule on double bonds or triple bonds in an organic moleculeLeads to reduction or saturationMostly a catalytic process

Eg.

3 atm, H2PdVegetable Oil HydrogenationProcess to turn unsaturated oils into saturated fats

Saturated fats have a longer shelf-life

Involves three major components- heat, metal catalyst and pressurized H2 gas.Why Monounsaturated Fats(MUFA)?Reduce risks of strokes, heart diseases and cancer

Help the body absorb nutrients

Reduces total cholesterol, triglycerides and LDL cholesterolProblemConvert polyunsaturated fatty acids (two or three double bonds) into monounsaturated fatty acids

No generation of completely saturated fatty acids and hence no increase in stearic percentage

Type of chemical transformation expected Linolenic C18:3 Linoleic C18:2 Oleic C18:1

Higher selectivity towards cis isomer of oleic acid

Heat and mass balance and cost per MT of feed

Basic ReactionPolyunsaturated fatty acids7-10% alpha linolenic acid, 51% linoleic acid, 23% oleic acidMonounsaturated fatty acidsCis-oleic acid (major)Trans-oleic acid (minor)Cu/SiO2453K, 2MPa, 1000rpmWhy Copper/Silica Catalyst?Extremely cheap

Mild and hence shows good selectivity

Comparatively non toxic

Better results as compared to its copper/chromite counterpart
