Another set of experiments were conducted to study the effect
of WHSV on the solketal yield and glycerol conversion at the reaction conditions of 40C, 600 psi and acetone equivalent of 2.0
under different WHSV (4.0 and 8.0 h
1
). The results are given in Table 3. It is evident that increasing the WHSV from 4 to 8 h
1
, both
the product yield and glycerol conversion decrease irrespective of
the catalysts used, simply because for reaction not being at equilibrium a shorter residence time (or larger WHSV) would led to a lower conversio
