Formatted abstract
Biodiesel has been identified as being the most promising substitute for petroleum fuels. The mass production of biodiesel is currently facing the challenge of a costly production. The need for a separation process of conventional homogeneous catalysts prevents an otherwise cheaper and more efficient continuous biodiesel production. The corrosive and reactive nature of these catalysts towards the equipments invokes a new search for a better biodiesel catalyst. Carbon-based solid acid catalysts allow a continuous biodiesel process by creating a heterogeneous mixture in the reactor. Sucrose has been reported as being a potential high performance solid acid catalyst. 3.4 grams of sugar-based solid acid catalyst have been successfully reproduced using the methodology outlined in the literature. The particle analysis done showed a similar material as reported in the literature, with surface area of 13.54 m2/g, an average pore diameter of 0.2014 ìm and a size distribution of 93.72 – 522.2 ìm. It is also found to be insoluble in water, methanol, heptane and coconut oil. However, no catalytic activity was detected in the biodiesel experiments done in the presence of the sugar-based catalyst. The experiments concluded that the sugar-based carbon acid catalyst does not possess any catalytic function, and the results reported in the literature could not be reproduced. It is recommended to move the search for an ideal solid acid catalyst to a different material in future work.
