| 8 | Beneficiation of coal using supercritical water and carbon dioxide extraction:sulfur removal显示文摘This work explores the use of carbon dioxide,water,and their mixtures as solvent for the precombustion beneficiation of raw coal without using any toxic mineral acids in the temperature range of 200-400℃.The fluid polarity,ionic constant,and supercritical point can be adjusted by H_(2)O/CO_(2)ratio and temperature.Adding carbon dioxide to hydrothermal fluid also increases the ionization by forming carbonic acid.Extractions with supercritical fluids have several benefits including enhanced mass transport,ease of separation and recycle,wide range of extractive capability and tunability,better inherent safety,and in the case of carbon dioxide and water-low cost.A semi-continuous extraction system was designed and built in which pressure,temperature and the relative flow rates of CO_(2)and H_(2)O can be controlled.Coal powder is kept in a packed bed and the extraction is carried out at 143 bar pressure.Using sulfur as a model heteroatom,extractive efficiency is examined as a function of the temperature,fluid composition,fluid flow,and extraction time.The results indicate that carbon dioxide,water,and supercritical water-carbon dioxide(ScWC)all can effectively extract about 50%of total sulfur from bituminous coal in 1 h.Extraction above 350℃decreased effectiveness,and extraction above the supercritical point of pure water caused hydrothermal carbonization.ScWC extraction may provide necessary control to prevent organic dissolution while removing sulfur. | Matthew J.DeCuir Ram B.Gupta Bhima Sastri | 2021 | International Journal of Coal Science & Technology2021，8，4： | 1 |

| 12 | Recovery of Total Heavy Minerals from Badlands of Basanputti Village,Odisha显示文摘The badland topography of Basanputti Village,Ganjam District,Odisha,possesses red sediments.The typical red sediment deposit,on average,consists of 71.8% total heavy minerals (THM),out of which 62.1% are ilmenite.The other heavy minerals sillimanite,zircon,garnet,monazite,and pyriboles are in the order of abundance identified.In this present study,Mozley mineral separator has been used to recover THM from red sediment.Mineral separator results indicate that a product obtained contains 72.2% by weight with 94.4% THM and 95% recovery.The ilmenite concentrate recovered using dry low-intensity magnetic separator from the THM concentrate can be used in pigment industries after suitable pyrometallurgical/chemical processing methods. | T Laxmi Rajalaxmi Mohapatra R Bhima Rao | 2012 | Journal of Earth Science2012，23，6： | 0 |
