Adsorbent body and method for making same

摘要

In accordance with the invention there is provided a porous adsorbent body comprising an array of granules of adsorbent material and particles of thermoplastic organic polymer bonded to the granules with at least some of the particles bridging contiguous granules thereby bonding them together to form a self-sustaining body having interstices which open into each other for admission of fluid to the surface of the granules in the interior of the body. Further in accordance with the invention such adsorbent body is made by forming a uniform mixture of the granules of adsorbent material and the particles of thermoplastic organic polymer and then heating the mixture to a temperature above the softening temperature but below the melting temperature of the thermoplastic polymer thereby to bond the granules together.
