Mixed oxide Zn-Fe with magnetic properties as a catalytic system for the aquathermolysis of heavy oil

Abstract

© 2020 IOP Publishing Ltd. All rights reserved. This article investigates the catalytic and magnetic abilities of mixed Zn-Fe oxides during aquathermolysis of heavy highly viscous oil. These systems influenced both the composition of the oil transformed during aquermolysis and its viscosity, moreover, the oil transformed using a Zn-Fe-MO sample (1:1) has a more flatter viscosity-temperature dependence. During magnetic manipulations, it was proved that a mixed Zn-Fe oxide with a ratio of Zn2+/Fe3+ = 2 cations in the synthesis of layered double hydroxide precursors shows better magnetization (the degree of extraction from the reaction was 91 wt %) and it can be removed from the reaction mixture.
