Claim:
1. A method comprising: a) providing a parent hydrocarbon-rich solid material; b) activating the parent material by exposing it to a hot gas stream at atmospheric pressure, the gas stream resulting from partial oxidation of the parent material using air along with additional carbon dioxide and/or steam, to produce activated carbon with a surface area of at least about 200 m c) adding supplemental fuel to the combustible gas and then combusting at least some of the combustible gas to produce heat; and d) using at least about 70% of the energy content of the combustible gas in a process comprising an endothermic step.
