摘      要：Non-thermal plasma exhibits unique advan-tages in biomass conversion for the sustainable production of higher-value energy *** homogeneous catalysts are usually required for plasma-enabled biomass liquefaction to achieve time-and energy-efficient ***,the effects of such catalysts on the plasma-assisted liquefaction process and of the plasma on those catalysts have not been thoroughly *** this study,an electrical discharge plasma is employed to promote the direct liquefaction of sawdust in a mixture of polyethylene glycol 200 and *** commonly used chemicals,sulfuric acid,nitric acid and sodium p-toluene sulfate,were selected as *** effects of the type of catalyst and concentration on the liquefaction yield were examined;further,the roles of the catalysts in the plasma liquefaction process have been *** results showed that the liquefaction yield attains a value of 90%within 5 min when 1%sulfuric acid was employed as the *** with the other catalysts,sulfuric acid presents the highest efficiency for the liquefaction of *** was observed that hydrogen ions from the catalyst were primarily responsible for the significant thermal effects on the liquefaction system and the generation of large quantities of active species;these effects directly con-tributed to a higher efficacy of the plasma-enabled liquefaction process.
