摘要
用共沉淀法加浸渍法制成Ni含量分别为0,5%,10%的Cu-Zn-Ni/Al2O3复合三元脱硫剂,通过天然气脱硫实验,研究了它们的脱硫性能。实验结果表明:合适的Ni含量会增强Cu-Zn-Ni/Al2O3脱硫剂的精脱硫性能,并且随着温度的升高,脱硫性能逐渐增强,最终会趋于稳定。5%Ni含量的Cu-Zn-Ni/Al2O3脱硫剂性能最优,在285℃、空速分别为400,1 200,2 400h-1条件下分别达到5,5,6Lμ/m3的脱硫深度。空速为400、1 200h-1时,不含Ni脱硫剂的脱硫性能优于含Ni 10%脱硫剂;空速为2 400h-1时,含Ni 10%脱硫剂的脱硫性能优于不含Ni脱硫剂。
Cu-Zn-Ni/Al2O3 desulfurizers having Ni contents of 0,5% and 10% were prepared by coprecipitation and impregnation methods, and their desulfurization performance was studied using natural gas as feed. Test results showed that suitable Ni content could enhance the fine desulfurization performanee of desulfurizer,and the fine desulfurization performance enhanced with the reaction temperature to reach a stable stage. Cu-Zn-Ni/Al2O3 desulfurizer having Ni contents of 5% exhibited the best desulfurization performance, under the temperature of 285 ℃, space velocity of 400,1 200 and 2 400 h-1, the sulfur content of treated natural gas reached 5,5 and 6 gL/m3 , respectively. When the space velocities were 400 and 1 200 h^-1 ,the desulfurization performance of Cu-Zn/Al2O3 desulfurizer was better than that of Cu-Zn-Ni/Al2O3 desulfurizer with Ni content of 10% ,yet under the space velocity of 2 400 h^-1 ,the re sults were reversed.
