Abstract
Method of making and using a proppant from captured carbon in either a carbon mineralization process or in a carbon nanomaterial manufacturing process is discussed, followed by treatments to ensure the quality control of the proppants so that they are suitable for use in hydraulic and other reservoir fracturing methods.
Claims18
A method of making a proppant for use in hydraulic fracturing of a well, said method comprising:
- a) capturing CO2 from a flue gas stream or from air;
- b) reacting said captured CO2 with electricity or heat or both to produce carbon nanomaterial (CNM);
- c) sonication and/or filtration of said CNM;
- d) optional shaping said CNM by vacuum forming or molding or agglomeration;
- e) said CMN having:
- (1) a crushing rate of <10% at 28 MPa,
- (2) a bulk density of 1.5-2.5 g/cm3,
- (3) a size of 0.1-2 mm, and
- (4) a porosity of 30-50%;
- f) size sorting said CMN to produce a size range of 20 mesh to 40 mesh, said size sorted CNM being suitable for use as a proppant.
