六种市售材料已被测试为颗粒吸附剂，用于颗粒床过滤器中，用于从加压流化床燃烧室（PFBC）的热（1073至1153 K）烟气中去除气态碱金属化合物，用于联合循环发电。在实验室规模的固定床燃烧室中，使用PFBC的模拟干烟气进行测试。硅藻土和活性铝土矿是两种最有前途的吸附剂。介绍了两种吸附剂的筛选试验结果，沿着讨论了温度、烟气表观速度和烟气空速对吸附性能的影响。可能的吸附机理，应用的吸附剂和初步的成本评估进行了讨论。
Six commercially available materials have been tested as granular sorbents to be used in granular-bed filters for the removal of gaseous alkali metal compounds from the hot (1073 to 1153 K) flue gas of pressurized fluidized-bed combustors (PFBC) for proposed combined-cycle power generation. Tests were performed using a simulated dry flue gas of PFBC in a laboratory-scale, fixed-bed combustor. Diatomaceous earth and activated bauxite were found to be the two most promising sorbents. The experimental results of screening tests are presented, along with the effects of temperature and superficial velocity and space velocity of the flue gas on the sorption performance for the two sorbents. Possible sorption mechanisms, applications of the sorbents and preliminary cost evaluations are discussed.
