The catalysts for methane dry reforming were commonly confronted with the problems of metal component agglomeration and carbon deposition. The catalysts made by solid-phase synthesis could effectively overcome these problems. In this paper, methane dry reforming was catalyzed over activated carbon supported Ni-catalysts prepared by solid-phase synthesis. Through this method, the catalysts exhibited a uniform metal dispersion over the carrier, with particle size at the nanoscale of 4.69 nm. Catalytic performance of the prepared catalysts was tested, and the results showed that the catalysts could effectively catalyze methane dry reforming, due to little metal agglomeration and the balanced competition between carbon deposition and carbon consumption. In the catalytic performance testing initiated at 900 °C, the conversions of CH₄ and CO₂ were maintained at 80.3% and 97.5% after the testing, respectively. It was also noticed the syngas generated in the testing process had a favorable H₂/CO ratio, at around 1. The syngas was considered to be beneficial to the synthesis of methanol, ammonia and oxygen-containing chemicals by Fischer-Tropsch process. It should be emphasized the reactant gases conversions presented an upward trend when the testing arrived at about 2 h, revealing an enhancement of catalyst activity. In totally, the catalysts prepared by solid-phase synthesis could avoid the agglomeration of active component and the serious carbon deposition, thus slowing down the catalyst deactivation. Through this work, it was demonstrated solid-phase method could open up new possibilities for the synthesis of highly active and stable catalysts for methane dry reforming.

甲烷干重整的催化剂通常面临金属组分团聚和碳沉积的问题。通过固相合成制备的催化剂可以有效克服这些问题。本文以固相合成法制备了活性炭负载的镍催化剂，对甲烷进行了干法重整。通过这种方法，催化剂在载体上表现出均匀的金属分散性，其纳米尺寸为4.69 nm。测试了所制备催化剂的催化性能，结果表明，由于金属团聚少，碳沉积与碳消耗之间的平衡竞争，该催化剂能够有效催化甲烷干重整。在900°C下开始的催化性能测试中，CH的转化率_{试验后，将4}和CO ₂分别保持在80.3％和97.5％。还注意到测试过程中生成的合成气具有良好的H ₂/ CO比约为1。合成气被认为对费-托法合成甲醇，氨和含氧化学物质是有益的。应该强调的是，当测试在约2小时到达时，反应物气体的转化率呈上升趋势，表明催化剂活性有所提高。总之，固相合成制备的催化剂可避免活性组分的团聚和严重的碳沉积，从而减慢了催化剂的失活速度。通过这项工作，证明了固相方法可以为合成高活性和稳定的甲烷干重整催化剂开辟新的可能性。
