The cobalt-molybdenum-based sulfur-resistant shift catalyst QDB-03 produced by Qingdao Lianxin Chemical Company consists, as its main components at the time of production, of cobalt oxide (CoO) and molybdenum trioxide (MoO3); its carrier is magnesium-aluminum spinel. The QDB-03 catalyst exhibits good activity in the temperature range of 180–500°C.
