Published: May 1, 2021

The rapid separation and efficient recycling of catalysts after a catalytic reaction are considered important requirements along with the high performances. In this view, although heterogeneous catalysis is generally less if compared to homogeneous type, it preferred since benefits from easy recovery catalyst. Recycling using traditional methods such as extraction, filtration, vacuum distillation, or centrifugation tedious time-consuming. They uneconomic processes and, hence, they cannot be carried out in industrial scale. For these limitations, today, research devoted development new that allow good catalysts. process should follow procedure economically technically feasible minimal loss solid aim work provide an overview about current trends separation/recycling used catalysis.
