Abstract

70033 Coal gasification has been under development for several years as a desirable means of power generation, with higher efficiency and lower emissions compared to current power-producing technologies. However, an effective method for controlling the emission of toxic metals such as mercury has not been devised. This project will demonstrate the feasibility of using treated zeolite sorbents to capture mercury and other pollutants in coal and coal/biomass gasification systems. In Phase I, zeolite-based multi-pollutant sorbents will be evaluated in a laboratory scale testing. Three different zeolite samples will be selected and treated with the proprietary additive. Then, the samples will be tested to determine their ability to capture mercury. Sorbent reusability will also be examined. Based on the laboratory data, a cost study will be performed to assess the economic advantages of implementing the technology in coal and coal/biomass gasification plants. In Phase II, the treated zeolite sorbent will be scaled-up and examined at the pilot-scale level in a coal gasification system. Commercial Applications and Other Benefits as described by the awardee: High mercury and other pollutant capture rates by the treated zeolite sorbent should speed the implementation of this emission control technology in gasification plants with a minimum addition of capital equipment and reduced overall process costs. In addition, this process may be applicable to any harsh industrial environment where the emission of mercury is a problem, such as solid waste incinerators, hazardous waste incinerators, and cement kilns.
