体相和SiO_2担载的Pd硫化物均表现出CO+H2(合成气)合成甲醇的活性。SiO_2担载的Pd硫化物在613K、5.1Mpa和20m~3(STP)kg-CAT−1h−1的条件下，甲醇产率为120g kg-CAT−1h−1。在浓度为120ppm的硫化氢存在下，其活性保持了无硫条件下的40%。
Both bulk and SiO2-supported Pd sulfides were found to show methanol synthesis activity from CO + H2 (syngas). SiO2-supported Pd sulfide yielded 120 g kg-cat−1 h−1 of methanol at 613 K, 5.1 Mpa and 20 m3 (STP) kg-cat−1 h−1. In the presence of H2S 120 ppm in concentration, it preserved 40% of the activity that was obtained under the sulfur-free conditions.
