Ireland Mine hvAb coal was used in the coal pyrolysis studies. The method of heat treatment was essentially that reported by Petrakis and Grandy (8), Ireland Mine coal was also the feed coal used to obtain most of the coal liquefaction products. The coal-derived liquids investigated were centrifuged liquid products (CLP) and their subfractions from selected runs in the Pittsburgh Energy Technology Center s 400-lb coal/day coal liquefaction process development unit (PDU) (9). 

The Pittsburgh Energy Technology Center (PETC) has conducted research and development on the copper oxide process for combined SO2 and NOx control since the late 1960s, but their largest pilot unit has been 1 MW. The PETC process uses the same chemistry as the Shell process, but fluidized bed or moving bed reactors are enqtloyed (Hoffman et al., 1992). 

PERC [Possibly named after the Pittsburgh Energy Research Center, now the National Energy Technology Laboratory] A process for making a heavy fuel oil by reacting a slurry of biomass in aqueous sodium carbonate solution with carbon monoxide. Under development in the United States in 1980.
