Work is on-going at Oak Ridge National Laboratory to evaluate refractory materials for containment applications in black liquor gasification. Materials have been evaluated and selected for low temperature gasification processes, with a number of materials being installed in commercial units currently in operation. For high temperature low pressure gasification processes, efforts have focused on screening candidate lining materials through immersion testing, improving existing refractory performance through the application of surface treatments, and the installation and evaluation of samples from an operating gasifier in New Bern, NC. Efforts concerning high temperature high pressure gasification have involved the identification and testing of suitable refractory materials for the coating of a helical carbon steel cooling coil arrangement.
