Previous studies have suggested that adjusting the gasification temperature can increase the hydrogen yield from biomass materials gasification . In a study by , the fraction of hydrogen in syngas was highest at a gasification temperature of 700 o C, and slightly decreased when the gasification temperature increased (750 o C or 800 o C). Another study by found that a gasification temperature of 700 o C offered the strongest hydrogen production for many biomass materials. However, the average gasification reaction rate and the concomitant production of CO, which are critical for industrial-scale implementation, were not investigated in either study. To analyze the characteristics of biochar gasification, the syngas generated from 300 o C-pyrolyzed ZMS (group 900-5-300) was first analyzed. As shown in Fig. As shown in Fig. and Table , the ratio of CO2 volume to CO volume (CO2/CO) declined with the temperature raised from 800 o C to 1000 o C. This indicated that the increase in gasification temperature promoted reaction 2. From the perspective of reducing the toxic gas CO, the low gasification temperature shifts the chemical equilibrium of reaction 2 to the direction of hydrogen generation during gasification, which improves the environmental friendliness and the energy conversion efficiency of this technology. Moreover, as displayed in Table , the hydrogen generation rate improved obviously with the elevation of gasification temperature from 800 o C to 900 o C, followed by a slight increase when the temperature increased to 1100 o C. Similar to the trends shown in previous studies , the total hydrogen yield declined with the elevation of gasification temperature.
