We have been developing a new hydrocarbon-based biodiesel fuel, HiBD (High quality Bio Diesel), which is produced through MgO-catalyzed decarboxylation of triglycerides. We have already demonstrated that high yield and selectivity of hydrocarbons of diesel fractions can be obtained using solid catalyzed vapor phase reaction in a pilot scale plant. However, long time operation was found difficult due to carbon deposition on the catalyst. In this research, we developed a novel slurry phase reaction system and a catalyst which is suitable for the system. Also, sudden boiling of the feed oil observed during the initial heating process was investigated.
