WebThe tests that reflect physical properties of the catalyst are surface area, average bulk density, pore volume (PV), and PSD. Surface Area (m 2 /g) For an identical fresh catalyst, the surface area of an E-cat is an indirect measurement of its activity. The SA is the sum of zeolite and matrix surface areas. WebKM1 is an iron-based ammonia synthesis catalyst containing a number of carefully selected promoters. Application. KM1 is used in the majority of the world’s ammonia converters to convert synthesis gas containing hydrogen and nitrogen into ammonia. An industry benchmark. Over the years, TOPSOE™ has supplied over 1,200 charges of KM1 catalyst.

WebThe first reports of FCC iron poisoning on a large-scale date from the 1990s. Iron was used in drilling liquids for oil recovery. Iron poisoning results in a loss of activity and an increase in slurry yield. The apparent bulk density of the catalyst decreases, which causes a drop in pressure differential over the standpipes and can lead to erratic catalyst circulation. WebThis catalyst is sulfur tolerant and can be used for most applications. Preferred choice for applications using organic bound silicon like anti-foaming agents.
