Cyclic olefins as new hydrogen donor compounds for coal liquefaction
- Auburn Univ., AL (USA)
A new set of hydrogen donor compounds, cyclic olefins (CLO), has been evaluated to determine their effectiveness as hydrogen donors to coal. These cyclic olefins are hydroaromatic species which do not contain aromatic rings. The efficacy of these donors has been compared to conventional hydroaromatics. The CLO's under study are 1,4,5,8-tetrahydronaphthalene, also known as isotetralin, and 1,4,5,8,9,10-hexahydroanthracene. In this paper, the thermal and catalytic reactivity of the CLO's under nitrogen and hydrogen at coal liquefaction temperature is discussed. Results for the reactions of the CLO's and their conventional hydroaromatic analogues, e.g. tetralin, 9,10-dihydroanthracene, and octahydroanthracene, with Western Kentucky No. 9 coal are discussed.
