饱和吸附容量为112.56 mg/g，比表面积为466.28 m

/g。相比热解炭，活性炭的比表面积更大，孔隙更加丰富，脱硫性能显著提高。

Abstract

Taking soybean straw rich in nitrogen-containing functional groups as the raw material precursor

combined with the special advantages of microwave heating

microwave heating technology is applied to the pyrolysis and activation process of soybean straw. The pyrolysis solid product is used as the activation raw material

and CO

is used as the activator to study the preparation of activated carbon

in order to prepare the biomass activated carbon with high desulfurization performance. First

the optimal activation level was obtained by orthogonal experimental design and range analysis. Then

the effects of microwave power

flow rate and activation time on the yield

pore structure and desulfurization performance of activated carbon were investigated by single factor experiment. The optimal activation conditions were selected by comparative analysis: microwave power 900 W

flow rate 0.10 L/min

activation time 20 min. Under these conditions

the yield of activated carbon is 76.3%(mass)

the SO

adsorbance quantity is 112.56 mg/g

specific surface area is 466.28 m

/g. Compared with pyrolytic carbon

activated carbon has larger specif

ic surface area and more abundant pores and significantly improved desulfurization performance.
