Abstract
Nanoscale Ce-ZrO 2, synthesized by cationic surfactant-assisted method, has useful partial oxidation activity to convert palm fatty acid distillate (PFAD; containing C 16-C 18 compounds) to hydrogen-rich gas with low carbon formation problem under moderate temperatures. At 1123 K with the inlet O/C ratio of 1.0, the main products from the reaction are H 2, CO, CO 2, and CH 4 with slight formations of gaseous high hydrocarbons (i.e., C 2H 4, C 2H 6, and C 3H 6), which could all be eliminated by applying higher O/C ratio (above 1.25) or higher temperature (1173 K). Compared with the microscale Ce-ZrO 2 synthesized by conventional coprecipitation method, less H 2 production with relatively higher C 2H 4, C 2H 6, and C 3H 6 formations are generated from the reaction over microscale Ce-ZrO 2. The better reaction performances of nanoscale Ce-ZrO 2 are linearly correlated with its higher specific surface area as well as higher oxygen storage capacity and lattice oxygen mobility, according to the reduction/oxidation measurement and 18O/ 16O isotope exchange study. ฉ 2010 American Institute of Chemical Engineers (AIChE).
