【 摘 要 】

This DOE NETL-sponsored effort seeks to develop continuous processes for producing carbon products from solvent-extracted coal. A key process step is removal of solids from liquefied coal. Three different processes were compared: gravity separation, centrifugation using a decanter-type Sharples Pennwalt centrifuge, and a Spinner-II centrifuge. The data suggest that extracts can be cleaned to as low as 0.5% ash level and probably lower using a combination of these techniques.
