Desulfurization and Denitrification processes in two pulsed discharge plasma systems (NO/SO2/N2/O2/H2O and NO/SOSubscript text2/NSubscript text2/OSubscript text2) were simulated respectively, and then the removal characteristics of these two gas systems were analyzed. The results show that NO can be completely removed when the residence time is close to 1.3 s and SOSubscript text2 removal rate is 61.5% when the residence time reaches 3 s in a system containing water vapor (HSubscript text2O). When the system does not contain water vapor, NO removal rate is still much high, but SOSubscript text2 removal rate is approximately zero. When OSubscript text2 concentration is increased, NO removal velocity will be faster and the peak of the concentration curve of NOSubscript text2 will be higher. NO removing velocity is much faster in a system containing water vapor than that in a system without water vapor when both systems have almost the same OSubscript text2 concentration.

Biomass resources in nature produce a large amount of waste resources (agricultural residues, wood waste, etc.) during agricultural and forestry production processes. Therefore, the effective utilization of these solid biomass waste resources has attracted widespread interest. In this paper, a pulsed discharge plasma technology was used to perform catalytic liquefaction experiments on solid biomass sawdust at room temperature and atmospheric pressure, and the reaction parameters such as the solid:liquid ratio, liquefaction solvent ratio, and catalyst ratio were optimized. The results showed that the plasma technology achieved a higher liquefaction yield; the optimized reaction parameters were: a solid:liquid ratio of 1:23.4, a liquefaction solvent polyethylene glycol (PEG) / glycerol (GL) ratio of 25:15 (V:V), and an acid volume fraction of 0.188%. In addition, the characteristics of the products of the liquefaction reaction were analyzed and discussed. The liquid products were mainly composed of small molecules. The experiment established that the liquefaction of solid sawdust by high-voltage pulsed discharge plasma can be an effective technical method.
