In order to better the present invention is described, have chosen traditional biomass rice husk as a comparison.Figure 16 is the TGA thermal gravimetric analysis curve of rice husk, and according to test result, rice husk is high ashy substance, and its ash content composition is mainly silicon-dioxide, consistent with the description about rice husk that current each seminar has delivered.First, under the condition identical with carbonization Carex meyeriana, carried out direct carbonization process to rice husk, and done low pressure, High Pressure Absorption is tested, as Figure 17, Figure 18, Figure 19.The BET specific surface of sample is 168m
2/ g, is less than the result of Carex meyeriana sample; From the situation of pore distribution, the scope of pore distribution is than in bagasse sample sets, all well is within the scope of 100nm, but totally not as Carex meyeriana sample, micropore, mesoporous, large porose area have distribution, from the situation of hysteresis loop and the peak heights of distribution curve, should mesoporous material be belonged to, but due to the dispersion of pore distribution, limit the application in some fields, to being 8.8mg/g(0.87wt% under the adsorptive power 35bar of methane), adsorptive power is more weak.
