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).

Developed and jointly licensed by Shell Oil Company and Dow Chemical Company. Introduced in 1987 by 1996, more than 20 units were operating and 10 were in design or under construction. The first application in coke making, in a plant near Pittsburgh, PA, was announced in 1996. 

Vacuum carbonate An improved version of the Seabord process for removing hydrogen sulfide from refinery gases, in which the hydrogen sulfide is stripped from the sodium carbonate solution by steam instead of by air. Developed by the Koppers Company, Pittsburgh, in 1939 two plants were using this process in the United States in 1950. 

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.

Zworykin, Vladimir (1889-1982) A Russian who emigrated to the United States after World War 1, Zworykin worked at the Westinghouse laboratories in Pittsburgh. An engineer and inventor who patented a cathode ray tube television transmitting and receiving system in 1923, he later worked in development for the Radio Corporation of America (RCA) in New Jersey, where his inventions were perfected in time to be used to telecast the 1936 Olympic Games in Berlin. He also contributed to the development of the electron microscope.

Zworykin received a scholarship and went to study X-rays at the College de France in Paris in the laboratory of a French theoretical physicist Paul Langevin, who was nominated for the Nobel Prize 25 times between 1910 to 1946. After the Russian Revolution, Zworykin emigrated to the United States in 1919, where he first worked at the Westinghouse laboratory in Pittsburgh on the development of radio tubes and photocells. In that period he defended his thesis on photoelectric cells and earned his Ph.D. in Physics at the University of Pittsburgh, Pennsylvania. But his main attention was devoted to the development of television and he patented the iconoscope in 1923 - the first of 120 patents. A little bit later he patented the kinescope, too. In 1929 he was appointed the new director of the Electronic Research Laboratory for the Radio Corporation of America (RCA) in Camden, New Jersey. In the same year, at a convention of radio engineers, Zworykin demonstrated the newly developed television receiver with the kinescope and applied for the first patent in color television. 

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).
