Abstract AITranslate

Formed catalyst was prepared by adding binders(sesbania powder,sodium carboxymethyl cellu-lose and guar gum)into sulphuric acid activated rare earth tailings catalyst powder.The effects of types and amounts of binders on the denitration performance of formed catalysts were investigated.The formed catalysts were characterized by means of catalytic activity evaluation,compressive strength test,BET,XRD and H2-TPR.The results show that after extrusion forming of catalyst powder,the specific surface area de-creases from 3.70 m2/g to 1.22 m2/g,and the denitration efficiency is only 56%.The addition of 2.5%guar gum enhances the adhesion among the rare earth tailings powder particles,enabling the catalyst to be smoothly extruded,and has the effect of pore formation,greatly improving the specific surface area and redox capacity of the catalyst.Under the combined action of 5%polyethylene glycol and 2.5%guar gum,the formed acid activated rare earth tailings catalyst has a denitration efficiency of 91.6%and excellent N2 selectivity,truly realizing the resource utilization of rare earth tailings.
