【摘要】：為研究適用于選擇性催化還原(SCR)脫硝催化劑的制備方法,實(shí)驗(yàn)探究了微波烘干和普通烘干制備得到的負(fù)載型鐵基催化劑8Mn-8Fe/Al_2O_3的催化脫硝活性和抗硫性,并用SEM、XRD、BET方法研究了這2種催化劑的結(jié)構(gòu)特性.結(jié)果表明:微波烘干后的催化劑在低于180℃時(shí)其催化脫硝活性顯著高于普通烘干的催化劑,且具有較好的抗硫性;經(jīng)微波烘干的催化劑表面顆粒分散度高,催化劑晶粒變小,孔隙結(jié)構(gòu)得到改善,比表面積有較大增加,從而提高了脫硝效率;在90℃時(shí),經(jīng)微波烘干的催化劑的脫硝效率比經(jīng)普通烘干的催化劑的脫硝效率高30%.
[Abstract]:In order to study the preparation method suitable for the selective catalytic reduction (SCR) denitrification catalyst, the catalytic denitrification activity and sulfur resistance of the supported iron based catalyst 8Mn-8Fe/Al_2O_3 prepared by microwave drying and ordinary drying were investigated. The structural properties of the 2 catalysts were studied by SEM, XRD and BET. The results showed that after microwave drying, the results showed that microwave drying was used. The catalytic denitrification activity of the catalyst at less than 180 C was significantly higher than that of the ordinary drying catalyst, and it had better sulfur resistance. The surface particle dispersion of the catalyst was high, the grain size of the catalyst was smaller, the pore structure was improved, the surface area was greatly increased, thus the denitrification efficiency was improved. The microwave drying was dried at 90 degrees C. The denitration efficiency of the catalyst is higher than that of the conventional drying catalyst 30%.
