Description:
Coal fired Gasifer Combined Cycles (GCC) have both high efficiency and very low emissions. A critical need for GCCs is a method of removing the H2S produced from the sulfur in the coal from the hot gases. There has been extensive research on hot gas clean-up systems, focused on the use of a zinc oxide based sorbent (e.g., zinc titanate). Unfortunately, current sorbents are relatively expensive, and the sorbent can be used for only a few cycles (less than 20) before it fall apart. What is needed is a low cost sorbent that also has a long life.TDA Research, Inc. (TDA) has develop a new method of producing sorbent ZnO based sorbents with greatly increased lifetimes and the potential for low costs. During Phase I, they demonstrated that the sorbent could have a long life and remain active. While TDA's formulation shows significant promise, additional work is needed to optimize formulation, demonstrate the capacity for many more cycles, and to evaluate the advantages of the new sorbent.
