Outline of Final Research Achievements

The aim of this research is the development of novel catalyst-loaded microcapsule reactors for the reactions. It was found that CaO(100 mg/mL)-active carbon(0.5 mg/mL)-loaded alginate capsules are most suitable catalyst system for BDF synthesis via methanolysis of rapeseed oil under light irradiation. Although the capsule breakage reached 53% after 6 h of the reaction, this system gave high BDF yield (60% for 1 h and 90% for 6h of the reaction) with a small amount (0.4% of charged CaO catalyst) of Ca leached into BDF phase. For the photo-catalytic degradation of methyl orange dissolved into water, it was confirmed that the permeation rate of methyl orange molecules through the alginate shell of the prepared capsules is much faster than the degradation rate of methyl orange on the catalyst encapsulated in the capsules. Thus, the degradation rate of methyl orange using the prepared capsules depends on the kinds of photo-catalysts loaded in the capsules.
