The primary purpose of this initial work was to establish under thermal and catalytic reaction conditions whether hydrogen transfer occurred between cycloalkane type structures that are present in resids and aromatics that are present in coal and liquefied coal. The research this quarter focused upon evaluating different reaction systems for performing model donor and model acceptor studies. The first system that was evaluated involved anthracene (ANT) as the model acceptor. Previous results had shown that ANT did not convert substantially in a thermal reaction at 380°C (Wang 1992); however, more was converted (about 50%) at 440°C. The results from the reactions performed last quarter indicated that substantial hydrogenation of ANT occurred thermally at 440°C; more than had been observed previously. The reactors that were used, though, had contained substantial amounts of catalysts prior to the performance of the thermal reactions. Hence, the passivity of the reactors was questioned and new reactors were fabricated. Some of the reactions using ANT were performed again and are reported herein. The second part of the work performed this quarter was to evaluate hydrogen transfer from the cycloalkane, perhydropyrene (PHP), to the aromatic phenanthrene (PHEN). Reactions were performed at a 1:1 PHP to PHEN weight ratio and with a 5:1 PHP to PHEN ratio. The reactions were performed thermally and catalytically at 400 and 425°C using molybdenum naphthenate and nickel octoate as catalysts. Reactions were also performed with added sulfur either as elemental sulfur or benzothiophene.
