Abstract

A catalytic proppant and methods for making and using same are disclosed herein. The catalytic proppant can include a proppant support containing silica and alumina. The proppant support can have a macropore concentration of about 15% to about 45%, a mesopore concentration of about 20% to 50%, and a micropore concentration of about 8% to about 30% based on the total pore volume of the proppant support. The proppant support can also have a surface area of about 0.5 m2/g to about 50 m2/g. The catalytic proppant can have a long term permeability at 7,500 psi of at least about 10 D in accordance with ISO 13503-5.
