Selective synthesis of methanol from CO+H-2 over Pd sulfide in the presence of H2S
Both bulk and SiO2-supported Pd sulfides were found to show methanol synthesis activity from CO + H-2 (syngas). SiO2-supported Pd sulfide yielded 120 g kg-cat(-1) h(-1) of methanol at 613 K, 5.1 MPa and 20 m(3) (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.
