Abstract
A method of making activated carbon particles from hemp includes placing raw hemp within a predefined atmosphere to produce activated carbon particles from the raw hemp and carbonizing the raw hemp to produce the activated carbon particles. Hemp filters including the activated carbon particles from hemp are disclosed.
Claims17
A filter, comprising:
- an enclosure;
- an inlet;
- an outlet fluidly coupled to the inlet;
- and
- a first filtering layer that comprises electrically charged activated hemp particles, wherein the activated hemp particles were created from raw hemp and further wherein the activated hemp particles are comprised of carbon atomic weight percentage of 0.31 or less,
- wherein the enclosure defines a flow path from the inlet, through the first filtering layer, and to the outlet to remove or reduce an element from a fluid flowing along the flow path.

A filter, comprising:
- an enclosure;
- an inlet;
- an outlet fluidly coupled to the inlet;
- and
- a first filtering layer that comprises electrically charged activated hemp particles, wherein the activated hemp particles were created from reactivated used hemp and further wherein the activated hemp particles are comprised of carbon atomic weight percentage of 0.31 or less,
- wherein the enclosure defines a flow path from the inlet, through the first filtering layer, and to the outlet to remove or reduce an element from a fluid flowing along the flow path.
