摘要
The invention relates to the treatment of crystals of ZSM-5 with mineral acid to produce ZSM-5 crystals which have an acid activity associated with the pores and channels thereof, the shape selective portion of the crystal, which is greater than the acid activity of the non-shape selective portion of the crystal or the surface of the ZSM-5 crystal, and the effect of the treated zeolite, as a catalyst component, in catalytic hydrocarbon conversions.
