Glycerol is the main byproduct in a biodiesel industry. It represents about 10
wt % of the biodiesel produced which led to a decrease of glycerol commercial price due
to its high abundance on the world market. Glycerol valorisation can be carried out in a
gas phase over heterogeneous catalysts, like acrolein, acrylic acid, dihydroxyacetone,
hydroxyacetone, allyl alcohol, and other chemicals. Recently glycidol was added to those
chemicals. Until now not a lot was studies in this area of glycidol production from
glycerol. This one step synthesis takes place in a packed bed micro reactor, packed with
a heterogenic catalyst HZSM-5 modified with CsNO3. In my work I was doing an
optimization of this reaction with studying three different parameters: mass
concentration, temperature and flow rate of carrier gas and feedstock glycerol. From the
results that I got, with time, this reaction could be transferred to industry with the help of
these optimizations.
