氢转移对煤的加氢液化至关重要。大量的研究结果表明，催化剂不仅可以加快氢转移反应的速度，而且影响氢转移反应的历程：温和条件下金属硫化物和活性炭促进单原子氢转移，导致煤中特定桥键的选择性断裂，而金属催化双原子氢转移，造成煤中芳环的加氢。传统的观点认为促进煤的加氢液化的供氢化合物对单原子氢转移起着显著的抑制作用。

Hydrogen transfer （HT） is crucially important for coal hydroliquifiction. Extensive investigations show that catalysts can not only accelerate HT rate, but also affect HT pathway： metal sulfides and activated carbon promote monatomic HT, leading to selective cleavage of special bridged bonds in coals, whereas metals catalyze diatomic HT, resulting in the hydrogenation of aromatic rings in coals. Hydrogen-donating compounds, which are considered to promote coal hydroliquifiction by conventional view point, remarkably inhibit monotomic HT.
