摘　　要：研究了硫酸镍、硫酸钴、硫酸钌、硫酸铑、硫酸银、硫酸镧、硫酸铈、硫酸汞、硫酸铅、偏钒酸钠、高铼酸钾、硫酸钾、硝酸钾、溴化钾和氯化钾在发烟硫酸中对甲烷转化的催化作用.结果表明,硫酸汞催化活性最高,溴化钾、硫酸银、硫酸镧和硫酸铅也有一定的催化作用.硝酸钾可以部分催化反应中生成的二氧化硫与氧气反应变回硫酸.The catalytic activity of several metal salts for low-temperature activation of methane in oleum medium was studied. The results show that KBr, Ag2SO4, La2 （SO4）3, PbSO4 and HgSO4 have good catalytic activity in the oxidation of methane to methyl bisulfate and the activity of HgSO4 is the highest. KNO3 has the ability to catalytically convert part of SO2 to H2SO4 and slow down the dilution of H2SO4.
