Potential pathways for utilisation of spent FCC catalyst from Dung Quat refinery
Abstract
The paper evaluates some pathways to recycle spent FCC catalyst at Dung Quat Refinery, with focus on some options to thoroughly utilise the spent FCC catalyst in a sustainable way, especially as building material. The results of testing in the laboratory and field survey show that the feasible pathways are ranked by spent catalyst recycling capacity as follows: raw material for cement production (20 - 200tons/day), pozzolanic material for cement additive production (> 15 tons/day), clay for red brick production (15 tons/day), and cement for concrete block production (11 - 17 tons/day).
