Corn stalk powder was processed in high pressure non-equilibrium plasma aiming to produce saccharide compounds by one step without oxidation and combustion.The results show that corn stalk powder can be splitted into saccharide compounds

such as monosaccharide and disaccharide etc.

in discharged plasma without any pretreatment and any additives.The optimized splitting conditions were found to be: 70℃ of circumstance temperature

90 kPa of pressure

0.35 L8226;min-1 of media gas N2 flow

0.1 L8226;min-1 of saturated vapour flow

3 kV of discharge voltage

0.60 mm of discharge gap

and 60 min of discharge duration. Under these conditions

the conversion of corn stalk powder was 69.36% with the selectivity of 39.68%

and the yield of saccharide compounds was 40.16%.These results clearly illustrated that the production of saccharide compounds by the splitting of corn stalk powder is possible without any acid or alkali or any other complicated pretreatment

and the process can proceed even with no needs of high temperature and high pressure.
