在新型提升管模拟器上对下行流化床中膜强化甲烷水蒸气重整反应进行了实验研究。钯膜和镍催化剂的实验表明，甲烷重整率是一阶相对于甲烷分压。速率常数为1.632×10−7± 10%mol/gcats，活化能为53，640 J/mol ± 60%。包含高温氢可渗透膜适度地增加了所观察到的甲烷转化率，同时产生适合于直接转化为甲醇的合成气。
A possible process for membrane enhanced steam reforming of methane in a downflow-fluidized bed is tested in a novel Riser Simulator. Experiments with a palladium membrane and a nickel catalyst indicate that the rate of methane reforming is first order with respect to the methane partial pressure. The rate constant was found to be 1.632×10−7±10% mol/gcats with an activation energy of 53,640 J/mol ±60%. Inclusion of a high temperature hydrogen permeable membrane moderately increases the observed conversion of methane while at the same time producing synthesis gas suitable for direct conversion to methanol.
