Chinese fertilizer plants, especially middle or small fertilizer plants, feed lump anthracite to atmospheric fixed bed gasifiers to produce fuel gas and syngas. However, the available lump coal meets less than one half the demand for fertilizer production, and the price of good lump anthracite has risen. Most good anthracite is produced in Shanxi Province. Chemical fertilizer plants in other areas pay high transportation costs and leave Shanxi mines with waste fine coal and slime that cause environmental pollution. So, it is important to fully utilize fine anthracite coal or bituminous coal to produce the industrial gasification briquettes. That may mitigate the disparity between supply and demand of lump coal, reduce the fertilizer production cost, and decrease the degree of environmental pollution. The briquettes don`t require heat-drying in their production and have the characteristics of high strength and water resistance. This technology is very important for local fertilizer plants where only meager-lean coal is produced. This paper discusses the processing technique and parameters, the quality standards and testing methods of briquettes made from meager-lean coal.
