</span>This is adsorption? Presumably the more internal surface area the<br class="">
more butane is retained. Most chars are only mildly activated and the<br class="">
effect is increased many fold by treating the char with an oxidant<br class="">
that will "pit" the structure.<br class="">

</span>As butane has three times the calorific value of wood it should be<br class="">
more but what's the point, for cooking, in devolatising wood to make<br class="">
char just to add a gas back?<br class="">
