Exxon's donor-solvent coal-liquefaction pilot plant will start up in May 1980, with Illinois No. 6 bituminous coal as feed. Contractors have already turned over parts of the 250 ton/day, $250 million Baytown, Texas, facility to Exxon Tests on various coal feedstocks and bottoms processing techniques will extend for 30 mo at an estimated cost of $350 million, to be shared 1:1 by the US Department of Energy and the industrial participants, including Exxon Corporation. Coal is ground to a 0.125-0.3 in. diameter, slurried with the donor solvent, a high-boiling distillate similar to creosote, to 46% solids, and preheated and liquefied in a noncatalytic reactor at 800/sup 0/to 880/sup 0/F and 1500 to 2000 psi. The donor solvent is constantly recycled and enriched with hydrogen in a separate catalytic reactor. Naphtha, middle and heavy distillates, and fuel oil are then distilled from the coal, leaving a bottom residuum that will be further processed by Exxon's Flexicoking route or partial oxidation.
