Claims23
A method of making activated carbon comprising:
- compressing a mixture of carbonaceous source material and an alkali source material in a press at a pressure ranging from 1,000 to 50,000 psi to produce a first solid form, wherein the mixture does not comprise a binder;
- and
- activating the first solid form to make a second solid form comprising an activated carbon, wherein the method does not comprise a dehydration step.
A method of making activated carbon comprising:
- combining a carbonaceous source material and a base of the formula MOH where M is K, Na, or combinations thereof, to form a mixture, wherein the mixture does not comprise a binder and wherein the base is in powder form;
- compressing the mixture into a first solid form;
- and
- activating the first solid form to form a second solid form comprising an activated carbon, wherein the method does not comprise a dehydration step.
