| description | Heterogeneous catalysts of K2CO3/γ-alumina and CaCO3/γ-alumina for
biodiesel production via transesterification of castor oil (Riccinus communis) have
been studied. The K2CO3 and CaCO3 salt (10 wt.%) was loaded on γ-alumina by
wet impregnation method, followed by calcination and oxidation produced
K2CO3/γ-alumina and CaCO3/γ-alumina catalysts. The prepared catalysts were
characterized by X-Ray Diffraction (XRD), Surface Area Analyzer (SAA) and
Barret Joyner Halenda (BJH) to analyze cristalinity, specific surface, total pore
volume and average pore radius of catalysts, respectively. Basicity of catalysts
were determined by the Hammett method.
Transesterification reaction of castor oil was conducted in a batch reactor
system at 60oC for 2 h. The parameters of catalyst to oil weight ratio and reaction
time were varied for conversion of the castor oil to biodiesel. The methyl esther
content on biodiesel product was analyzed with GC-MS and American Standard
of Testing Materials (ASTM) of biodiesel.
The result show that impregnation of K2CO3 and CaCO3 to γ-alumina
were decreased specific surface area and increased basicity and average pore
radius of γ-alumina. The highest catalytic activity yielded 95% biodiesel under the
condition of 5 wt.% K2CO3/γ-alumina for 150 min. The catalyst selectivity toward
methyl ricinoleate of GC analysis and liquid product were 91.81% and 87.22%. |
