HYDROLYSIS OF POLYCARBONATE USING A FLUIDIZED BED REACTOR

摘要：

The hydrolysis of polycarbonate was investigated to recycle the monomer of Bisphenol-A (BPA). Experiments were carried out with a laboratory scale sand bed fluidized by superheated steam. The yield and the selectivity of BPA were examined under various conditions such as bed materials, temperatures and feed rates. The production rate of BPA increased with increasing temperature whereas the selectivity of BPA decreased with increasing temperature. By using olivine sand as a bed material, the hydrolysis rate increased remarkably due to the catalytic effect by minerals in the sand. When the olivine sand was used, the yield of BPA increased with temperature up to 350℃, and at the temperatures higher than 350℃, the yield of BPA decreased due to the decomposition of BPA.
