Activation of a nickel-chromium catalyst for low temperature steam reforming of C₂₊-alkanes to methane rich gas has been studied by TPR and XRD in situ techniques. The activation procedure has been studied with the following reducing agents: hydrogen, syngas, methanol and the reaction mixture of low-temperature steam reforming. Attempts were made to activate the catalyst at 300, 340 and 420 °C. Activated samples were tested in low-temperature steam reforming of a methane-propane mixture. A passivation process has been proposed and tested for compatibility with following activation in the LTSR reaction mixture.

活化镍铬催化剂以进行C ₂₊烷烃的低温蒸汽重整

已经通过TPR和XRD原位技术研究了用于将C ₂₊烷烃低温蒸汽重整为富含甲烷的气体的镍铬催化剂的活化。用以下还原剂研究了活化过程：氢气，合成气，甲醇和低温蒸汽重整的反应混合物。试图在300、340和420℃下活化催化剂。在甲烷-丙烷混合物的低温蒸汽重整中测试了活化的样品。已经提出了钝化工艺，并测试了其与LTSR反应混合物中后续活化的相容性。
