  The exploitation of using agro-industrial residues as the cherry stone to
produce charcoal and activated carbon is very relevant nowadays due to the high
demand of these materials and their environmental advantages. This work
describes the methods to prepare charcoal from cherry stones (CS) using final
heating temperature of 600 {\deg}C, with or without the application of an equal
flow of nitrogen or air. The isothermal time has been of 2 hours, an adequate
time to study carbonisation by varying the atmosphere. The charcoal obtained
has the appropriate characteristics as precursors of activated carbon. Of the
three samples prepared in different atmospheres, *N, N~ and AN, the third is an
activated carbon. It is evidenced that the yield in material carbonaceous is
somewhat lower when applying the nitrogen current and approximately 5% less
when applying the air current. For the different samples, in this work we have
studied the effects of the atmosphere during the heat treatment of CS, the
yield, the chemical composition and the structure, as well as the pore
structure of the same.
