| Abstract: | Making use of the fact that the acidic sites of the surface on HM zeolite has the catalytic activity for the disproportionation reaction of methylbenzene and using triphenylphosphine as the external active sites poison,the ratio of the internal surface active sites to the total active sites can be obtained.The internal surface area can be calculated after the total surface area is measured with usual method for surface area determination. |
