Phase I, Volume II, Theoretical and bench scale research at TRCB (Texaco Research Center in Beacon, New York)
The objective of this work was to identify and characterize in-situ sulfur capture sorbents for use in coal gasification tests at the Montebello Research Laboratory. The work addressed two tasks: (1) theoretical studies of in-situ desulfurization and slag-sorbent interactions and (2) bench-scale testing to study the behavior of slag and slag/sorbent systems under slagging gasifier conditions. The theoretical studies included literature searches, thermodynamic equilibrium calculations, optical basicity calculations and predictions of ash/sorbent interactions utilizing published phase diagrams. Based on cost considerations and the results of the theoretical studies, compounds of iron, sodium and calcium were selected for bench scale testing. The bench-scale tests primarily consisted of exposing mixtures of coal ash and sulfur sorbents to simulated synthesis gas at temperatures within the range of those found in a Texaco gasifier for sufficient time to reach equilibrium. After rapid quenching, the resulting slags were extensively analyzed to determine the various phases that were formed. The viscosity of the slags was also measured to assess potential operating problems in the gasifier. 65 refs., 30 figs., 19 tabs.
