摘要：This work aims a comparative study on the structure and adsorption capability of oilshale based materials resulting carbonates removal from the rock. The oil shale fromTarfaya mine was treated using four acids: chloric acid (OSH), Phosphoric acid (OSP),sulfuric acid (OSS) and nitric acid (OSN). The obtained materials were characterized bythermo gravimetric (TG), Fourier transform infrared spectroscopy and scanning electronmicroscopy. The results showed that the acid used to remove carbonates obviouslyaffects the chemical composition and the texture evolution of the residues. The removalof volatile compounds resulted in pores with enhanced rough and irregular surface.Porosity and the adsorption capability of the resulting materials were significantlyincreased when the rock was treated with chloride acid.
