Effective coke removal in methane to benzene (MTB) reaction on Mo/HZSM-5 catalyst by H2 and H2O co-addition to methane

The catalytic dehydro-aromatization reaction over Mo/HZSM-5 catalyst was drastically stabilized by the co-addition of 5.4% H-2 and 1.8% H2O to methane feed at 750 degrees C, 0.3 MPa and methane space velocity of 3000 mL g(-1) h(-1), suppressing the coke formation effectively, compared with single hydrogen or steam addition.
