Abstract

Characteristics of ZrO2 polycrystalline ceramic foam catalyst including crystal structure, phase composition, and microstructure were analyzed by Py-IR, XRD, SEM, and BET. Effects of preparation conditions such as calcination temperature, calcination time, ZrO2 (catalyst matrix), Al2O3 (flux), TiO2 (stabilizer), NaHCO3 (low-temperature pore-forming agents), and NaCl (high-temperature pore-forming agents) on catalytic activity were investigated. The optimum composition of ZrO2 polycrystalline ceramic foam catalyst were optimized using response surface methodology (RSM) to be 88.47% ZrO2, 9.62% Al2O3, 3.31% TiO2, 10% NaHCO3, and 25% NaCl (compared with the standard number 100). After calcination at 1550°C for 120 min, fatty acid methyl ester conversion rates were substantially maintained at around 97.31%, The FAME content in the product oil exceeded 97% after five successive reuses of the catalyst. In addition, catalytic activity did not significantly fluctuate. The proposed catalyst presents a new type of solid catalyst with excellent catalytic activity and stability.
