【摘要】 通过在TG上程序升温催化裂解甲烷实验,研究了不同Ni负载量的氧化金刚石催化剂对甲烷催化活性的影响。研究表明,Ni负载量越多,催化剂催化活性越高。氧化金刚石作载体的Ni基催化剂在550℃的温度条件下,甲烷催化裂解效率较高,80min内甲烷转化率维持在7%以上;空速对甲烷转化率影响较大,空速越快,转化率越低。指出氧化金刚石将是一种有效的催化剂载体材料。更多还原

【Abstract】 The effects of various Ni loading oxidized diamond catalysts on catalytic activity of methane are discussed by decomposition of methane on TG. The more Ni loading is,the higher catalytic activity is. The methane conversion is high relatively at 550℃,which maintains above 7% for 80 minutes. Space velocity has great influence on methane conversion. The high space velocity makes low conversion of methane. Oxidized diamond is proposed as an effective catalyst support material.更多还原
