| Popis: | 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. |
