制备了LiOH成品粒、粉尘抑制型LiOH颗粒和变色LiOH颗粒三种CO2吸收剂,研究了粒径在0.8mm～6mm范围内粒度大小对三种CO2吸收剂的CO2吸收容量影响。结果表明:LiOH成品粒随着粒度的增大,吸收容量逐渐降低,粒径在0.8mm～6mm范围内的吸收容量均大于0.70g/g;粉尘抑制型LiOH颗粒和变色LiOH颗粒随着粒度的增大,吸收容量逐渐增大,当粒径大于3mm时,CO2吸收剂吸收容量大于0.70g/g。 Three kinds of CO2 absorbers, LiOH, LiOH and CD, were prepared. The effect of particle size on the CO2 absorption capacity of three CO2 absorbers was studied in the range of 0.8mm ~ 6mm. The results showed that with the increase of particle size, the absorption capacity of LiOH finished products decreased gradually. The absorption capacity of LiOH finished products was more than 0.70g / g in the range of 0.8mm ~ 6mm. The particle sizes of LiOH, Increase, the absorption capacity gradually increased, when the particle size is greater than 3mm, CO2 absorbent absorption capacity greater than 0.70g / g.
