Coal Desulfurization by Solvent Leaching Methods

Coal desulfurization prior to usage is a preprocessing in order to achieve clean fuel and reduce environmental impacts such as acid rain. Desulfurization of Lakhra (Pakistan) coal was conducted with different solvents. Coal was leached with different solvents like hot water, H2O2/H2SO4 and HNO3. It was found that the effects of the leaching temperature, agitation time and particle size on the r...

Hot Coal Gas Desulfurization With Manganese-Based Sorbents

The objective of this project is to develop a pellet formulation which is capable of achieving low sulfur partial pressures and a high capacity for sulfur, loaded from a hot fuel gas and which is readily regenerable. Furthermore the pellet must be strong for potential use in a fluidized bed and regenerable over many cycles of loading and regeneration. Regeneration should be in air or oxygen-dep...

Sodium Hypochlorite Generation

Low concentration (0.5-0.8%) sodium hypochlorite is a viable solution for point-of-use drinking water chlorination programs in Nepal, and it can be produced on a small-scale at a low cost using relatively cheap, safe, and robust generators, appropriate for developing country conditions. This thesis describes the set-up and the testing of a sodium hypochlorite generator in Kathmandu, at the labo...
