Spent cobalt-based macroporous adsorbents are considered to be used for the hydrotreating process. Herein, spent materials from low-temperature desulfurization process were as organic sulfur catalysts. Physicochemical properties of waste characterized and performance COS conversion was evaluated at different conditions. The Co-containing exhibit considerable hydrogenation low temperature, resid...

The paper presents the results of detailed structural analysis and 40 Ar/ 39 Ar dating deformations in Golets Vysochaishii deposit area. geological studies showed folded-deformation sequence from large lying folds through axial-plane cleavage formation to quartz-filled fractures. syntectonic sericite yielded ages two Hercynian tectonic impulses – 340 320 Ma. This stage is characterized by earli...

This work describes the optical and structure properties of nickel sulfide and cobalt sulfide nanoparticles in ZSM-5 zeolite. The samples were obtained by sulfidation of the Ni2+ and Co2+ ion-exchange ZSM-5 zeolites in a Na2S solution at room temperature. The optical properties of the samples were studied by UV-visible spectroscopy. Their crystalline structure and morphology were studied by X-r...
