Abstract
Disclosed is a process for the one-pot liquefaction of a biomass or coal and a biomass, the process comprising: first preparing a slurry containing a catalyst, a vulcanizing agent and a biomass (and coal), and then introducing hydrogen gas into the slurry to carry out a reaction. Preparing the slurry comprises: subjecting a biomass (and coal) sequentially to drying, a first pulverization, compression and a second pulverization, then mixing same with a catalyst and a vulcanizing agent to obtain a mixture, and adding the mixture to an oil product for grinding and pulping to obtain a biomass slurry. By means of the treatment process of subjecting the straw firstly to compression and then to a second pulverization, the volume of the straw is greatly reduced, thereby facilitating the dispersion thereof in the oil product.
