Advances in the Study on Hydrogen Transfer to a,w-Diarylalkanes Ni Zhonghai, Zhang Lifang, Wang Junling, Zong Zhimin, Wei Xianyong* (School of Chemical Engineering, CUMT, Xuzhou 221008) Abatract As the most relevant coal model compounds,a,w-diarylalkanes (DAAs) were extensively investigated for studying mechanism of coal liquefaction. The advances in the study on hydrogen transfer to DAAs are reviewed in the paper. The effects of catalyst, hydrogen donor solvent and molecular structures of DAAs on hydrogen transfer to DAAs were mainly discussed. The emphasis is laid on basic research of coal liquefaction to realize high added-value utilization of coal.
