Resumen: Activated carbon is an important filter material for the removal of different compounds such as hazardous components in exhaust gases, for purification of drinking water, waste water treatment, adsorption of pollution from liquid phases, in catalysis, electrochemistry or for gas storage and present an important demand. Theoretically, activated carbon can be produced from any carbonaceous material rich in elemental carbon, and because of this, a large variety of waste biomass have been used in the literature with this end. Materials such as straw, wood, residues from olive oil production, fruit shells and stones, coffee endocarp have been evaluated as precursors of different activated carbon. Microalgae have a higher photosynthetic efficiency, larger biomass, faster growth than other biomass such as trees and require lower amount of nutrients. Because of this, microalgae can be considered as an interesting source of valuable products and a new precursor of activated carbons. In the present work, the char obtained in the pyrolysis of the microalgae Nannochloropsis sp. has been subjected to a physical activation. The activation was carried out in an horizontal laboratory scale reactor, using carbon dioxide as activation agent. Different temperatures and activation times have been evaluated, analyzing the influence of these parameters on the characteristics of the activated carbons obtained. All products have been characterized by nitrogen adsorption-desorption isotherms and surface area and pore size distribution have been calculated by BET and BJH methods. The results obtained allow us to conclude about the viability of this process.
