摘要: The catalytic properties of ferrospheres containing 76–97 wt % Fe2O3 in the oxidative condensation methane were compared with their phase composition and distribution iron cations over crystallographic positions iron-containing phases a steady state. It was established that reaction route oxidation changed at content 89 %. Deep main on <88.8 At ≥89 %, yield C2 hydrocarbons sharply increased contribution deep decreased. correlated amount defects structure spinel, which are ions tetrahedral cation Ca2+ octahedral vacancy among nearest neighbors.
