| Abstract | The article describes research carried out on four coals samples (raw coals A and B and enriched coals A and B). The fuels were subjected to low-temperature thermal treatment in order to remove as much mercury as possible while still maintaining high energy quality of the fuels. The lab-scale tests were performed in a fluidized bed column and for chosen coal fraction 500-1000µm. Air and a mixture of carbon dioxide (16%) and nitrogen (the rest) were used as the fluidizing medium that as intended to have similar composition as the synthetic flue gas. The coals were tested for five temperatures of 200, 250, 300, 350 and 400°C.The results indicated that it was possible to remove more than 80% of mercury from coal A (raw and enriched), in CO2/N2 atmosphere at the temperature of 400°C in the case of coal B, both raw and enriched, the amount of removed mercury at 400°C was roughly 70%. At lower temperature, 350°C, the amount of removed mercury was 70% and 60% for coals A and B, respectively. Apart from the above test the investigation were also carried out in order to determine the loss of volatiles during the thermal treatment of the coals. The results indicated that at 400°C roughly 20% of the volatiles were evolved from the fuel particles. The loss of elemental carbon and fuel higher heating value (HHV) after the treatment were 10% and 8%, respectively. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
