The Electric Power Research Institute (EPRI) is conducting research to investigate mercury removal in utility flue gas using sorbents. Bench-scale and pilot-scale tests have been conducted to determine the abilities of different sor-bents to remove mercury in simulated and actual flue gas streams. Bench-scale tests have investigated the effects of various sorbent and flue gas parameters on sorbent performance. These data are being used to develop a theoretical model for predicting mercury removal by sorbents at different conditions. This paper describes the results of parametric bench-scale tests investigating the removal of mercuric chloride and elemental mercury by activated carbon. Results obtained to date indicate that the adsorption capacity of a given sorbent is dependent on many factors, including the type of mercury being adsorbed, flue gas composition, and adsorption temperature. These data provide insight into potential mercury adsorption mechanisms and suggest that the removal of mercury involves both physical and chemical mechanisms. Understanding these effects is important since the performance of a given sorbent could vary significantly from site to site depending on the coal- or gas-matrix composition.
电力研究协会（EPRI）正在开展研究，以调查利用吸附剂去除公用事业烟道气中的汞。已进行了实验室规模和中试规模的测试，以确定不同吸附剂在模拟和实际烟道气流中去除汞的能力。实验室规模的测试研究了各种吸附剂和烟道气参数对吸附剂性能的影响。这些数据正用于开发一个理论模型，以预测不同条件下吸附剂对汞的去除情况。本文描述了研究活性炭去除氯化汞和元素汞的参数实验室规模测试结果。迄今为止获得的结果表明，给定吸附剂的吸附容量取决于许多因素，包括被吸附汞的类型、烟道气组成和吸附温度。这些数据为潜在的汞吸附机制提供了见解，并表明汞的去除涉及物理和化学机制。了解这些影响很重要，因为根据煤或气体基质组成，给定吸附剂的性能在不同地点可能会有显著差异。
