Low severity coal liquefaction promoted by cyclic olefins. Quarterly report, October 1994--December 1994

Technical Report ·
OSTI ID:49162
The research performed during the October to December 1994 quarter centered on two areas. The first area involved the writing of a paper based on research performed on this project concerning the mild acidic pretreatment of low rank coals and their liquefaction behavior in the presence of hydrogen donors with different reactivities. The second area that was worked on during the quarter was the high temperature infrared analysis of cyclic olefins. The work is ongoing and is currently involving a considerable amount of equipment and technique development. Cyclic olefins, such as 1,4,5,8-tetrahydronaphthalene (isotetralin) and 1,4,5,8,9,10-hexahydroanthracene (HHA), are highly reactive hydrogen donor compounds that readily donate their hydrogen to coal and model acceptors when heated. Numerous reactions have been performed using these cyclic olefins with high rank and low rank coals as well as with model acceptors. In each case the cyclic olefins have proven themselves to be active donors. Further evaluation of the reactivity of these donors with pretreated low rank coals and at different temperatures is described more fully in this report.
