8 IEA CLEAN COAL CENTRE Gasification is a process by which coal can be converted into syngas CO H 2 that can then be used to produce a range of chemicals either directly or via intermediates such as methanol Typically 1 kg of bituminous coal can be converted into 1517 m 3of syngas The coal chemical industry product chain can be
The size reduction process actually starts with the mining of the coal and the top size and size consist of the mined coal is dependent upon the type of mining system employed The mined coal undergoes primary breakage in crushers where the top size is reduced to the range of 8 to 3
Jan 12 2018 Within an ore body valuable minerals are surrounded by gangue and it is the primary function of mineral processing to liberate and concentrate those valuable minerals 13 RunOfMine Material and Minerals Generally mineral processing begins when an ore is delivered from a mine to a processing facility
The top size for these gasifiers is usually less than 100 mm while the bottom size is in the range of 58 mm Coal preparation does not involve drying for fixedbed gasifiers as drying of coal occurs within the gasifier using the sensible heat of the syngas Higman and van der Burgt 2008
