Abstract
The porosity of heterogeneous type catalysts is increased by incorporating during the preparation a short fibrous type material commonly referred to as a whisker. This type material is highly effective in increasing the volume and diameter of the pores in the catalyst.
Claims13
A method of increasing the BET micro pore volume and pore diameter of a catalytic material prepared from an inorganic oxide gel by incorporating into the catalyst mix, before drying and without subsequent removal, a calcium sulfate whisker fiber having a diameter less than about 5 microns, a length less than about 100 microns, and having a length to diameter ratio of at least about 3.
