Ni-Carbon Mineral Sorbent - Catalyst of Sulfur Dioxide Sorption

Abstract

The morphology and structure of Ni-carbon mineral sorbent-catalysts on the basis of local mineral raw material were studied by methods of thermoprogrammed desorption and electron microscopy. The specific<br />surface, filamentary carbon diameter sizes and sorption characteristics of sulfur dioxide adsorption were determined. It was shown that the adsorption capacity of carboncontaining sorbents is influenced by: nature of metals of varying valence, specific surface and density of patterns. Physical and chemical sorption of sulfur dioxide was shown experimentally.

Evaluation of Synthetic Conditions for H3PO4 Chemically Activated Rice Husk and Preparation of Honeycomb Monoliths

“…When choosing adsorbents and catalyst supports, highly developed porous structure is a preferable property. A special niche in this field belongs to natural porous materials [15,16] including rice husk [17,18]. Usually, these materials are represented by powders or granule pieces having wide particle size dispersion and low mechanical strength.…”
