Overview of catalyst testing and coprocessing studies at Sandia National Laboratories

PDF Version Also Available for Download.

Description

Prior to the initiation of Sandia`s fine particle size catalyst testing project, it was not feasible to compare the activities of the many direct coal liquefaction catalysts developed in various laboratories. This was due to the wide variety of testing methods used by the different catalyst developers. Sandia developed a procedure that uses a bituminous coal (DECS-17 Blind Canyon coal), phenathrene as the reaction solvent, and a factorial experimental design with three variables: temperature, time, and catalyst loading. Numerous catalysts have been evaluated. Pacific Northwest National Laboratories` (PNNL) 6-line ferrihydrite catalyst is the most active among the particulate catalysts. West ... continued below

Description

Prior to the initiation of Sandia`s fine particle size catalyst testing project, it was not feasible to compare the activities of the many direct coal liquefaction catalysts developed in various laboratories. This was due to the wide variety of testing methods used by the different catalyst developers. Sandia developed a procedure that uses a bituminous coal (DECS-17 Blind Canyon coal), phenathrene as the reaction solvent, and a factorial experimental design with three variables: temperature, time, and catalyst loading. Numerous catalysts have been evaluated. Pacific Northwest National Laboratories` (PNNL) 6-line ferrihydrite catalyst is the most active among the particulate catalysts. West Virginia University`s (WVU) iron catalyst impregnated on Blind Canyon coal is the best iron catalyst evaluated to date. Because this catalyst was prepared by impregnation, which involves several preparation steps, it cannot be directly compared to particulate catalysts. In an effort to enable this comparison, WVU produced a particulate iron catalyst that has been tested at Sandia. In addition, Sandia has also evaluated several of Argonne National Laboratory`s molybdenum and iron catalysts that were impregnated on Wyodak subbituminous coal from the Argonne Premium Coal Sample Program. Current activities are focused on developing capabilities for performing coprocessing experiments to support FETC`s coprocessing thrust and a new project aimed at helping Puerto Rico solve its waste disposal problems.
