LF-94 Sulfur Tolerant Shift Catalyst

  Catalyst LF-94 is a kind of Co-Mo system CO sulfur tolerant shift catalyst containing new additives and special carrier, suited to shift process gas production with coal, heavy oil or residual oil as the feed as well as city gas production with mid pressure process (1.0-5.0Mpa). Specifically, LF-94 is suitable for mid pressure ammonia plant with coal as the feed.

  LF-94 has the advantages of high mechanical strength, high low temperature activity, easy sulfurization and regeneration, low alkali metal loss rate as well as easy preparation process. The operating life is about 3-8 years, which is related to the operating conditions. The active components Co and Mo are in the state of cobalt oxide and molybdenum oxide in fresh catalyst. When used, the catalyst should be sulfurized first, converting the metal oxides into sulfides. Either the sulfurizing agent or the sulfur containing process gas can be used as the sulfurizing agent. The composition of LF-94 is simple, not containing alkali metals or the substances harmful to equipment and human bodies. When being sulfurized, only a small amount of water is produced and drained off with process gas, with no harmfulness to sulfurizing process or the equipment.
