Studies on Co2 Gasification Reactivity of High Ash Indian Coal
Coal is a prime energy source in India and will continue to play its role for coming several decades. However, our indigenous coal suffers from high ash content and present coal based conventional power generation technologies have several drawbacks such as, lower efficiency, environmental loading and damages thereof. Herein the importance of gasification lies because coal gasification is a mea...
متن کاملMinerals in the Ash and Slag from Oxygen-Enriched Underground Coal Gasification
Underground coal gasification (UCG) is a promising option for the recovery of low-rank and inaccessible coal resources. Detailed mineralogical information is essential to understand underground reaction conditions far from the surface and optimize the operation parameters during the UCG process. It is also significant in identifying the environmental effects of UCG residue. In this paper, with ...
متن کاملa study of underground coal gasification (ucg) wastewater and sludge
underground coal gasification (ucg) is a non-conventional method of extracting gas from coal. the primary advantage of ucg is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world’s coal reserves by an estimated 70%; for this reason, ucg has been implemented at sites around the world. however, the gaseous, liquid and solid waste streams which ac...
متن کاملComparison of phosphorus recovery from incineration and gasification sewage sludge ash.
Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty in...
متن کاملToxicity mitigation and solidification of municipal solid waste incinerator fly ash using alkaline activated coal ash.
Municipal solid waste (MSW) incineration is a common and effective practice to reduce the volume of solid waste in urban areas. However, the byproduct of this process is a fly ash (IFA), which contains large quantities of toxic contaminants. The purpose of this research study was to analyze the chemical, physical and mechanical behaviors resulting from the gradual introduction of IFA to an alka...
