One of the more efficient routes for utilization of biomass resources, including black liquor, is high temperatureproduction, through gasification or pyrolysis, of a synthesis gas (syngas) that can be used directly as a fuel orconverted into higher value liquid or other chemicals. However, experience has shown that the environmentsproduced in many of the gasification systems are very aggressive toward the materials used to construct thecontainment structures. For many of these systems, degraded components have been examined, laboratorysimulation studies have been conducted, and alternate materials have been identified. These alternate materials havesuccessfully addressed many of the problems encountered. However, proposed gasification systems, sometimeswith higher temperatures and even more severe and exotic environments, will likely put further demands onstructural materials requiring additional evaluations and new materials solutions.
