The theroy of fractal geometry in mathematics has been introduced to describe the catalyst morphology.Catalyst surface fractal dimension was measured by Box dimension model.It was found that the catalyst surface can not be described by a single fractal dimension
but some kind of distribution existed.It obeys the nomoal distribution regularity.The distribution function can be used to characterize the non-uniformity on the catalyst surface.Promoters and supports can affect the fractal dimension significantly.The space time yield for methanol correlated well with the fractal dimension of catalyst.When the dimension exceeds a certain specfied value
