LF710/LF710R ammonia synthetic catalysts are mainly used in converting N2 and H2 into synthetic ammonia, or used to decompose ammonia into H2 and N2. They are suited to each kind of ammonia converters of large, medium and small ammonia plants, suited to all industrial pressure ranges, and suited to various high and low pressure processes, esp. suited to medium and low pressure ammonia synthesis.
LF710 has activity only after reduction by H2 and N2 in ammonia converter; while LF710R is a kind of pre-reduced catalyst, whose reducing time is only 20-30% of that of LF710.
