| Abstract: | The texture of an alumina coked at 873–923 K has been studied by specific area measurements and determination of pore size distributions. Two opposite textural changes have been observed: a strong plugging of the microporosity (r=18–30 Å) and an increase of the porous volume and surface area of the larger porosity (r=30–1000 Å).
               ,   873–923  ,             .  : (r=18–30 Å) (r=30–100 Å).
