Cobalt oxide-alumina catalysts for the methane-assisted selective catalytic reduction of SO₂ to sulfur.

ABSTRACT: Preventing emission of pollutants in any kind, is a way to protect global environment. The objective of this study is to develop cobalt catalysts supported on alumina for the conversion of the toxic gas SO₂ into elemental sulfur using methane. Although several useful catalysts have been proposed, there is still a need to synthesize a catalyst with a high sulfur yield that is also persistent during on-stream stability. To this end, four different catalysts were prepared using the wet impregnation technique, with Co₃O₄ content ranging from 0 to 15 wt%. Catalytic activity tests were carried out at atmospheric pressure and temperatures ranging from 550 to 800 °C. The Al₂O₃-Co (15 %) catalyst exhibited superior performance, with a sulfur yi
