摘要

摘要采用功率为450 ~ 850 W、辐照时间为6 ~ 12 min的微波装置对冶金焦、生物质焦和半焦进行了改性,并对改性前后的三种碳材料的脱硫率进行了测试。采用扫描电镜(SEM)、BET和傅里叶变换红外光谱(FTIR)研究了微波功率和辐照时间对三种碳材料孔隙结构和表面化学特性的影响。结果表明:辐照后生物质炭和半焦的比表面积、总孔容和孔径均略有减小;值得注意的是,微波改性后碳的孔径变小,表面酸性官能团分解,从而提高了碳表面的碱度。三种碳材料的最佳脱硫效果为850 W半焦辐照9 min,二氧化硫吸附率可达45%。

Sintering flue gas desulfurization with different carbon materials modified by microwave irradiation

Abstract

Modification of metallurgical coke, biomass char and semi-coke was carried out using a microwave device with power of 450–850 W and irradiation time of 6–12 min. The desulfurization rates of three carbon materials before and after modification were tested. The effects of microwave power and irradiation time on the pore texture and surface chemical characteristics of the three carbon materials were examined by SEM, BET and Fourier transform infrared spectroscopy (FTIR). The results showed that the specific surface area, total pore volume and pore diameter of biomass char and semi-coke after irradiation decreased slightly. Noteworthily, the pore diameter turned small and the acidic functional groups on their surface decomposed, thereby the basicity of carbon surface increased by microwave modification. The optimal promotion of desulfurization rate of three carbon materials was semi-coke irradiated at 850 W for 9 min and the sulfur dioxide adsorption rate was up to 45%.
