Component for solar adsorption refrigeration system and method of making such component

A method for producing an adsorbent material, the method comprising:

• providing a first activated carbon precursor having a first density;
• providing a second activated carbon precursor having a second density in contact with the first activated carbon precursor to form a structure;
• and pyrolyzing the structure to form an adsorbent material that includes a plurality of pores therein, the adsorbent material comprising a first region corresponding to the first activated carbon precursor and a second region corresponding to the second activated carbon precursor;
• wherein at least one of the pore sizes and the pore distribution differ between the first region and the second region.

An adsorbent material in an adsorption structure comprising:

• at least one adsorbent member formed of an adsorbent material;
• and at least one porous member provided in contact with a portion of the adsorbent member to allow gas to enter and exit the portion of the adsorbent member, said adsorbent material comprising:
• a first region having a first pore distribution;
• a second region having a second pore distribution;
• wherein the first region is formed from a first polymeric material having a first density and the second region is formed from a second polymeric material having a second density.
