| 英文摘要 | the non-supported ni catalyst was prepared by calcination of the nickel hydroxide precipitate, originated from precipitation of nickel acetate with aqueous solution of sodium carbonate, rinsed with ethanol the influence of pretreatment conditions on ni catalyst was investigated by means of x-ray diffraction, ch(4) temperature-programmed surface reaction, and ch(4) decomposition reactivity test the results showed that lowering the reduction temperature could reduce ni particle size and correspondingly improve the catalytic activity of ni catalyst for ch(4) decomposition the result of the catalytic activity test showed that reaction history was an important factor influencing the catalytic activity of the ni catalyst for ch(4) decomposition at 500 degrees c the formation of relatively stable ni particles could be realized by carrying out ch(4) decomposition stepwise at multiple reaction temperatures (multiple step temperature elevating decomposition), which could remarkably improve the catalytic activity and stability of the ni catalyst for ch(4) decomposition the initial ch(4) conversion reached 8 40% at 500 degrees c by using the multiple step temperature elevating decomposition method, and the ch(4) conversion could further be increased to 11 20% within 120 min. whereas by the two step temperature elevating decomposition method, the maximum ch(4) conversion at 50 degrees c was only 1 61% |
