The Influence of Ac and Ni/Ac Catalyst in the Antioxidant Additives Production From Argan Shells Lignin

Abstract

The production of antioxidant additives via the hydrothermal treatment of lignin from argan shells (agricultural waste) was evaluated in the current study. Specifically, the effect of using a Ni catalyst supported on activated carbon which had been prepared from the same waste (argan shells), has been studied. Adding activated carbon (without Ni load) to the reaction medium slightly improved the additives' production, while no significant effect on its antioxidant activity was observed.
