摘要：Improvement of coking properties of sub-bituminous coal (A) and bituminous coal (B) was done using blended organic solvents,namely,n-methyl-2-pyrrolidinone (NMP) and ethylenediamine (EDA).Various solvent blends were employed for the coal extraction under the total reflux condition.A low-cost ceramic membrane was fabricated using industrial waste iron ore slime of M/s TATA steel R&D,Jamshedpur (India) to separate out the dissolved coking fraction from the solvent-coal mixture.Membrane separations were carried out in a batch cell,and around 75 ％ recovered NMP was reused.The fractionated coal properties were determined using proximate and ultimate analyses.In the case of bituminous coal,the ash and sulfur contents were decreased by 99.3 ％ and 79.2 ％,respectively,whereas,the carbon content was increased by 23.9 ％ in the separated coal fraction.Three different cleaning agents,namely deionized water,sodium dodecyl sulphate and NMP were used to regain the original membrane permeability for the reusing.
