We had found that calcium-oxide is as active as alkali-hydroxide in a transesterification of soybean oil, which indicated a heterogeneous catalytic process for biodiesel production utilizing solid-base. In this paper, the biodiesel production with calcium-oxide catalyst was studied for the used cooking oil. An increase in the acid value and an accumulation of the nitrogen compounds were obvious for the used restaurant oil. The oil degradation provided the induction period for the transesterification in the experimental biodiesel production, although the transesterification was completed at 2h independent of the oil degradation. Solution of the catalyst was the serious problem for the processing of the used restaurant oil.
