| Summary: | Glycerol, an abundant by-product of biodiesel production, is
urgently considered to increase its usage. Triacetin produced from glycerol is an
important material, used in polyester, cryogenics, cosmetics and as a biodiesel
additive. Using homogeneous catalysts in triacetin production involves high
product separation costs. The purpose of this study is to synthesize
heterogeneous catalysts based on alumina and silica from peat clay for use in the
production of triacetin from glycerol. The conversion of glycerol for triacetin
production using such alumina and silica catalysts yielded levels of 82.7% and
87.4% respectively. These values were greater than the conversion value of
71.2% using a sulfuric acid homogeneous catalyst. An optimum conversion of 91%
was obtained at the mole ratio of glycerol to acetic acid of 8.9. The potential
heterogeneous catalysts were confirmed by the results of SEM, XRD and BET
characterization. Therefore, the production of triacetin using heterogeneous
silica catalyst could be an alternative approach in commercial processes which currently
using homogeneous catalysts. |
