High-pressure liquefaction of a sawdust in syngas and hydrogen with tetralin as solvent was performed in an autoclave,and the effects of temperature,reaction time and initial reaction pressure on the sawdust high-pressure liquefaction were studied by testing the distribution and characteristic of liquefaction products.The effects of atmosphere on the products distribution and characteristic of sawdust liquefaction were also compared.The results show that the oil yield increases with increasing temperature,r...
