This work was supported by the Department of Energy, Grant //ET-78-G-01-3382. Preliminary studies were also supported with funds from the Purdue Coal Research Center. We wish to acknowledge very helpful discussions with T. Ruppel of the Pittsburgh Energy Technology Center (PETC). The coal samples were kindly provided by the Pennsylvania State University, College of Earth and Mineral Sciences. 

A question of considerable interest in coal hydroliquefaction chemistry is the amount and nature of "organically bound metals in the coal. One reason for this interest is the observation that when supported metal direct conversion catalysts are used in liquefaction reactors, a primary mode of deactivation is metals deposition Q, 2). In particular, recent work at the Pittsburgh Energy Technology Center (PETC) (4,5) and elsewhere (3) has indicated very high levels of titanium deposition on supported Co Mo catalysts used in the fixed bed continuous reactor system. It has been suggested that the culprits in such deposition are soluble metal species (6 9) The analyses of a Western Kentucky (Homestead) hvBb feed coal and of material deposited between the catalyst pellets in the fixed bed reactor at PETC (4) are shown in Table I. 

Product oils from direct liquefaction of Blacksville Number 2 coal in the 1000 pound per day pilot plant at Pittsburgh Energy Technology Center (PETC) were examined by cyclicvoltammetry.

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).
