Kinetic behaviour of catalysts with different CuO-ZnO-Al2O3 metallic function compositions in DME steam reforming in a fluidized bed

- A high H2 yield is obtained with the catalyst with Cu/Zn/Al atomic ratio = 4.5:4.5:1.0.
- Desilicated HZSM-5 zeolite is an active and stable acid function.
- Hydrogen yield is 0.83 at 325 °C.
- A 1.0:1.0 Cu/Zn atomic ratio is suitable for enhancing Cu metal dispersion.
- Deactivation is caused by a small amount of coke deposited on the metallic function.
