Catalyst LF112 is suited to synthesis ammonia plants with inferior sulfur removing conditions, containing higher H2S and organic sulfides. It can be widely used under atmospheric pressure or pressured conditions. It has the characteristics of good low temperature activity, good sulfur resistance, low steam consumption and high mechanical strength.
1 Properties of LF112
LF112 is produced as per HG3546-2002 standard. Its main active component is iron oxide and main assistant catalyst is chromium oxide, and some other species are also added. The main properties of LF112 are listed in Table 1.
