摘要

引言浸渍活性炭是一种低温、高效脱硫剂

其硫容量可达52%以上

特别适合于低H_2S浓度的天然气脱硫净化过程。活性炭孔结构是影响脱硫效率的关键因素

许多人曾对此作过研究

但结果却很不一致

如Swinarski和Siedlewski的研究表明脱硫活性与孔径在3.5nm—8nm的孔表面积成正比

而认为小于3.5nm的孔没有脱硫效果

并且反应生成的硫最初总是覆盖在8nm—30nm的大孔中

这种硫不影响催化活性。Sreeramamurthy和Menon分析了活性炭孔内生成的硫

其结果表明反应最初阶段生成的硫沉积在相当于20个硫原子的大孔内

这部分约占总的硫生成量的70%

而后才填充到直至4个硫原子的微孔中

Steijins和Mars研究了不同孔结构物质的脱硫效果

发现孔径在0.5nm—1nm范围内的微孔具有最高的催化活性

太大和太小的孔的脱硫效果则要弱得多。

Abstract

The effects of the pore structure of activated carbon and the humidity of inlet gas on desulfurization activity have been investigated. The experimental results showed that the pores within the range from 1 nm to 5 nm had the best desulfurization activity

and the relative humidity of inlet gas should be within 0. 85 -0. 95. These operating conditions are beneficial to increase in the volume of the water film

which favors improving the desulfurization rate and sulfur capacity.
