The content of CO in the yellow phosphorus tail gas  reaches up to 90%. Yellow phosphorus tails gas belongs to the ore smelting tail gas whose components are complicated and impurities are various. The existence of phosphorus and sulfur in the tail gas utilization may corrode the equipment and shorten the life of the catalyst, so the utilization rate is quite low. The yellow phosphorus resource is abundant in China and deposit reaches 800-1000 thousand tons, which weighs 80% in the world. In absence of the efficiency and advanced purification technique and utilization mode, the yellow phosphorus plant only burns little tail gas to dry the raw material or for the boiler combustion but most of the tail gas is discharged, thus greatly wasting the resource, intensifying the environmental pollution and obstructing the energy saving and emission reduction. Besides, the resource utilization of C1 chemical products requires deep purification of the impurity in the raw gas, but impu...
