Hydrogen transfer reactions of model compounds typical of coal
The hydrogen transfer reactions involving some model compounds, representing the bonds and functional groups typically found in coals, namely dibenzyl, dibenzyl ether, benzyl phenyl sulfide, acetophenone, and benzaldehyde have been studied. The hydrogen donating capabilities of tetralin, tetrahydroquinoline, and molecular hydrogen, and the catalytic effect of SRC residue have been examined. Hydrogen can be abstracted more easily from tetrahydroquinoline than the tetralin. Hydrogen pressure has a marked effect on the rates of conversion of dibenzyl ether, benzyl phenyl sulfide, acetephenone, and benzaldehyde. SRC residue catalyzes the hydrogenation of carbonyl groups to a significant degree and the conversion of dibenzyl ether and benzyl phenyl sulfide to a lesser degree. The rate of cracking of dibenzyl is not affected by the presence of SRC residue.
