Abstract
An aluminosilicate ceramic, spherical pellet made from spent ceramic catalyst. More specifically, a spherical ceramic pellet made from spent fluid cracking catalyst. The pellets can be made by grinding the catalyst particles, forming them into spherical pellets, and then sintering the pellets. The final product is useful as a proppant in oil and gas well fracturing.
Claims30
A spherical ceramic proppant pellet comprising spent fluid cracking catalyst particles, wherein the pellet is formed by:
- a. reducing the median particle size of the catalyst;
- b. mixing the catalyst particles with water and a binder to form spherical pellets;
- and
- c. sintering the pellets.
A method for preparing a spherical ceramic proppant pellet, the method comprising:
- a. providing spent fluid cracking catalyst particles;
- b. reducing the particle size of the catalyst particles;
- c. mixing the catalyst particles with water and a binder to form spherical pellets;
- and
- d. sintering the pellets.
A proppant pellet composition comprising pelletized and calcined spent fluid cracking catalyst, wherein the spent fluid cracking catalyst comprises from about 25 to about 80 weight percent silica, and from about 20 to about 75 weight percent alumina.
