Study of Methanol Conversion over Fe-Zn-Zr Catalyst

The methanol conversion over Fe-Zn-Zr catalyst was studied at 0.1 MPa and 280-360℃.The experimental results indicate that the main products of methanol conversion are methane and butane,and that other hydrocarbons are scarcely produced.All results show that propylene is most probably the olefin formed first in methanol conversion rather than ethene over Fe-Zn-Zr catalyst.Methane is formed from methoxy group,and C4 is possibly yielded on the surface from propylene through binding with a methoxy group.
