Formation of the Active Surface of the FeCrAl Catalyst under Electric Current Heating Conditions

An effect of heat treatment conditions (convective, resistive heating) was considered on the composition and surface properties of FeCrAl wire used as a catalyst for methane decomposition. It was shown that resistive heating is a more effective method for activating the FeCrAl wire catalyst, which promotes the dispersion of iron-enriched particles over the surface and an increase in the number of catalytically active sites. The use of resistive heating allows reducing the catalyst pretreatment time to 10 min.
