Simultaneous recovery of rare earth elements and phosphorus from phosphate rock by phosphoric acid leaching and selective precipitation:Towards green processShengxi Wu1,2,Longsheng Zhao1,Liangshi... of the major components from phosphate rock. A REEs recovery of 94.3% and a phosphorus recovery of 95.3%are achieved under the optimal conditions of attacking phosphate rock using 30%P2 O5 acid with an L......
concentration of 0.9-2.5 g/m3. The Mn/AC catalyst is applicable to removing COS in yellow phosphorus tail gas. Moreover, deactivation of the catalyst is due to the gradual poisoning of the surface alkalescence hydroxyl by the formation of sulfate along with the COS removal. Key words: manganese; modified activated carbon; carbonyl sulfide; yellow phosphorus tail gas 随着现代化学工业迅速发展和人民生活的日益提高,天然气,石油气,焦炉......
