Preparation of coal slurry with organic solvents.
In this study, various organic solvents were used to prepare coal slurries and the rheological and thermal properties of coal-organic solvent slurries were examined. Solvents with molecules containing unpaired electrons (high basicity) show high extraction power and cause swelling of coal. Therefore, coal-organic solvent slurries usually showed higher viscosities compared to coal-water slurry. ...
متن کاملPreparation of coal slurry with 2-propanol.
This study explored the feasibility of using waste organic solvents as substitutes for water to prepare coal slurries. The rheological properties of coal-2-propanol slurries were examined and compared with that of coal-water slurry (CWS). The good compatibility between coal particles and 2-propanol resulted in stable particle suspension in slurry which usually exhibit Newtonian behaviour. Howev...
متن کاملA Resource and Technology Assessment of Coal Utilization in India
Electricity production in India is projected to expand dramatically in the near term to energize new industrial development, while also easing the energy shortages throughout the country. Much of the new growth in electricity production will be fueled by domestic coal resources; however, there is worldwide concern about increased coal use, as greater carbon dioxide (CO 2) emissions from coal co...
متن کاملDesign of Atomizers and Burners for Coal-water Slurry
A novel extensional viscometer was developed to measure the extensional properties of aqueous solutions of polymeric material and coal water slurries (CWS) containing additives. When a drop of viscoelastic liquid or CWS containing additives is allowed to form at the end of a capillary tube, it starts to fall once its weight exceeds the retaining force exerted by surface tension. In experiments ...
متن کاملHigh Pressure Oxydesulphurisation of Coal Using KMnO4—Effect of Coal Slurry Concentration, pH and Alkali
A high pressure oxydesulphurisation technique was investigated to reduce sulphur content, especially at ambient temperature. Prince of Wales coal was chosen for this study. The focus of the study was on the reduction of both pyritic and organic sulphur. The effects of pressure, coal slurry concentration, pH and KOH concentration in a fixed time interval on sulphur removal were studied with a se...
