Desulfurization property of ultrafine zinc oxide (ZnO) particles produced by laser ablation was investigated. Studied were 1) influence of reactor pressure on the size and specific surface area of produced particles, 2) influence of powder properties on sulfidation rate and 3) desulfurizating model of ZnO particles. The particle size produced by the laser ablation was directly proportional to the reactor pressure, i. e., 7.8 nm at 1.33 × 10<SUP>4</SUP> Pa, 16 nm at 6.66 × 10<SUP>4</SUP> Pa being independent of the laser power. Sulfidation rate increased with decreasing particle size and became constant when the specific surface area was larger than 20 m<SUP>2</SUP>/g. The characteristic desulfurization property could be explained by assuming that ZnO particles produced by laser ablation consist of Zn:O, 1:1.
