Progress on task 1 (high temperature chlorine cleanup) is reported. Findings include: (1) the primary candidates for chloride cleanup are the alkali and alkaline earth carbonates or oxides; (2) ZnCl/sub 2/ and FeCl/sub 3/ are gaseous above 800 K and melt below 600 K, which could have severe implications for cleanup of sulfur with Zn/Fe oxides from streams where chloride is present; (3) very little information is available on kinetics and pore plugging of sorbents during chloride cleanup; however, we find that for cleanup by limestone (limited data is available) that chloride enhances sulfur cleanup rates and should not plug the pores as long as the chlorine level is less than the sulfur level; and (4) the alkali carbonates appear to be by far the best sorbents for combined sulfur/chloride cleanup. Progress is also reported on task 2, soot control for molten carbonate fuel cell anode. Experiments run with various gas mixtures on smooth Ni surfaces, supported Ni catalyst and anode material have led to the conclusion that the Boudouard reaction for carbon deposition is much faster at fuel cell conditions than either the water shift reaction or the methanation reaction. These results imply that carbon may form on MCFC anodes even for conditions where equilibrium calculations predict no carbon. Addition of CO/sub 2/ will inhibit coke formation even if the shift reaction is too slow to accommodate changing compositions.
