Potassium-promoted MoS2 is an active catalyst for mixed alcohol synthesis from CO and H2. When K2CO3/MoS2 is oxidized, however, it produces mostly hydrocarbons, of which 40–50 wt% are C2–C4 alkanes. The reaction rates also substantially increase. Since oxidized K2CO3/MoS2 can tolerate a high level (up to 300 ppm) of H2S in the CO-H2 feed, it could serve as a novel sulfur-resistant Fischer-Tropsch catalyst.
