Unravelling the metal–support interactions in χ-Fe₅C₂/MgO catalysts for olefin synthesis directly from syngas

Abstract

We reported the χ-Fe5C2/MgO catalyst for olefins synthesis directly from syngas (STO), showing high selectivity to C2-C4 olefins and catalytic stability. With characterization of morphology, electronic structures, and adsorption/desorption properties...

Effect of the Zr promoter on precipitated iron-based catalysts for high-temperature Fischer–Tropsch synthesis of light olefins

“…Light olefins (C 2 = –C 4 = ) are essential chemical raw materials for producing various chemicals including detergents, drugs, fibers, etc. 1 They are traditionally made by catalytic cracking of heavy feedstocks and steam cracking of naphtha derived from crude oil. 2 However, the disadvantages of these processes are high energy consumption and excessive CO 2 emissions.…”
