Abstract

Long-term performance of two barium-containing catalysts in the transesterification was studied in the flow fixed bed reactor during 50-60 h at the temperature of 200 (228) °C, the pressure of 20 (30) atm and the liquid hourly space velocity of 0.8-2 h - 1. The performance of the Ba 0.04La 1.96O 3 catalyst is sustained at very high level during 50 h and then declines sharply. The BaAl 12O 19 catalyst exhibits lower performance but higher stability. The change of the phase or surface composition of the catalysts monitored by X-ray diffraction or X-ray photoelectron spectroscopy are the cause of the diminution of the performance.
