WebAbstract. The kinetic behaviour of the Ce 0.70 La 0.20 Ni 0.10 O 2− δ catalyst during the methane dry reforming reaction was investigated in a fixed bed reactor in the temperature range of 923–1023 K with the partial pressure of CH 4 and CO 2 ranging between 5 and 50 kPa. The experimental data were fitted using the empirical power-law rate equation and … WebIn petroleum refining: Naphtha reforming) In catalytic reforming, as in thermal reforming, a naphtha-type material serves as the feedstock, but the reactions are carried out in the presence of hydrogen, which inhibits the formation of unstable unsaturated compounds that polymerize into higher-boiling materials.
