Hydrodenitrogenation of quinoline with red mud catalyst.

Catalytic Pyrolysis of General Purpose PolyStyrene Using Red Mud as a Catalyst

Effects of Impregnation Methods and Drying Conditions on Quinoline Hydrodenitrogenation over Ni-W Based Catalysts

Os efeitos dos métodos de impregnação (co-impregnação e impregnação sequencial) e das condições de secagem (ar e vácuo) sobre estrutura e o comportamento catalítico de catalisadores Ni-W suportados em MCM-41 foram investigados. Os catalisadores foram caracterizados por difratometria de raios X de pó (XRD), espectroscopia de absorção no infravermelho com transformada de Fourier (FT-IR), espectro...

Adsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud

Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive r...

Physical and Chemical Properties of Sintering Red Mud and Bayer Red Mud and the Implications for Beneficial Utilization

Performances of two common types of red mud, Bayer red mud and Sintering red mud, were investigated in this research. Their compositions, mechanical properties and microstructure characterization were measured through XRD, TG and SEM analysis. Their shear strength, particle size, density and hydraulic characteristics also had been performed. Huge differences between the basic mineral types of t...
