Shanxi uses coal gangue to make phosphorus-substituting additives. The latest technological achievement of using coal gangue to produce phosphorus-substituting additive LN-4A zeolite has recently passed the expert appraisal organized by the Shanxi Provincial Department of Science and Technology. This scientific and technological achievement has reached the domestic leading level and opened up a new way for the comprehensive utilization of coal gangue. According to relevant sources: The coal gangue accumulation in Shanxi Province reaches more than 900 million tons, and is increasing at a rate of 20-30 million tons per year. It not only wastes resources and occupies land, but also seriously pollutes the environment. Local enterprises in Shanxi Province have successfully used the phosphorus-substituted additive LA-4A zeolite technology prepared from coal gangue to produce phosphorus-substituted additive LN-4A zeolite products, which can be widely used in daily chemical, petrochemical, biochemical and other industries. The product has high added value and considerable economic and social benefits.
