Description
Summary:Alumina-based catalysts play an essential role in the process of optimizing crude oil processing. The oil production process uses widely Platinum/alumina (Pt/Al2O3) that is an alumina-based catalyst, consequently leaving a lot of catalyst waste. In this catalyst waste, Pt metal is a vital content included, which has a high economic value. This study focused on processing Pt/Al2O3 catalyst waste to separate Pt metal content from the catalyst. The optimization of Pt metal separation was carried out using a sonoleaching procedure under different conditions. By increasing the sonoleaching temperature, we noted the significant color of the catalyst is changing, and the mass is reduced. Furthermore, the effect of temperature on the recovery of Pt metal was investigated by morphological analysis and elemental content in Pt/Al2O3 catalyst waste. Our results will provide additional knowledge and reference in optimizing Pt recovery in Pt/Al2O3 catalyst waste to reuse Pt metals in various applications.
