Abstract

A structure fabricated of a zeolite-based paste with an intra-layer continuous wire embedded is disclosed. Vitally, the continuous wire is extended past the bounds of the structure's walls, creating bare wire leads that allow for connection to a power source for electrification. The structure is made of multiple layers stacked together, typically in an additive manufacturing (3D printing) process. Within this structure, at least one layer has an embedded wire running through at least some portion of it, and is equipped with two bare wire leads protruding from the structure. This wire is designed to act as a heating element for uniform Joule heating of the zeolite structure for reduced power consumption and temperature ramp-up time during a desorption process, as well as reduced system footprint and enhanced mechanical properties. The frequency of wire embedment (a wire embedded in every n th layer), the percentage of the embedded layer that contains the wire, and the wire gauge and material/composition can be modified for the desired application.

First claim

What is claimed is:

1 . An adsorbent structure prepared by a process comprising the steps of: beginning a first extrusion of a length of bare wire to create a first wire lead; followed by a co-extrusion of the wire and a zeolite to create a wire-embedded structure layer, and finishing with a second extrusion of a length of bare wire to create a second wire lead.

2 . An adsorbent structure formed from a continuous wire and zeolite, comprising:
at least a first layer having a perimeter wall and roads within the perimeter wall formed from a first extrusion of a first length of bare wire to create a first wire lead, a first co-extrusion of the wire and the zeolite; and a second extrusion of a second length of bare wire to create a second wire lead.

3 . The adsorbent structure of claim 2 , further comprising:
a second layer having a perimeter wall and roads within the perimeter wall formed from an extrusion of the zeolite only, and wherein the second layer is adjacent the first layer.

4 . The adsorbent structure of claim 3 , further comprising:
a third layer having a perimeter wall and roads within the perimeter wall formed from a third extrusion of a third length of bare wire to create a third wire lead, a second co-extrusion of the wire and the zeolite, and a fourth extrusion of a four length of bare wire to create a fourth wire lead, and wherein the third layer is adjacent the second layer.

5 . The adsorbent structure of claim 4 , further comprising:
a fourth layer having a perimeter wall and roads within the perimeter wall formed from an second extrusion of the zeolite only, and wherein the fourth layer is adjacent the third layer.

6 . The adsorbent structure of claim 5 , wherein the first wire lead, the second wire lead, the third wire lead, and fourth wire lead run parallel.

7 . The adsorbent structure of claim 6 , wherein the first wire lead and second wire lead run parallel to each other, the third wire lead and the fourth wire lead run parallel to each other, and the first wire lead and second wire lead run orthogonal to the third wire lead and the fourth wire lead.

8 . An adsorbent structure formed from a continuous wire and zeolite, comprising:
at least one wire-embedded-zeolite layer having a perimeter wall and roads within the perimeter wall formed from a first extrusion of a first length of bare wire to create a first wire lead, a first co-extrusion of the wire and the zeolite; and a second extrusion of a second length of bare wire to create a second wire lead.

9 . The adsorbent structure of claim 8 , further comprising:
at least one zeolite layer having a perimeter wall and roads within the perimeter wall formed from an extrusion of the zeolite only.

10 . The adsorbent structure of claim 9 , wherein the at least one wire-embedded-zeolite layer and the at least one zeolite layer alternate one layer on top of the other layer to form a multi-layered absorbent structure.

11 . An adsorbent structure array formed from a continuous wire and zeolite, comprising:
a wire-embedded-zeolite layer having a perimeter wall and roads within the perimeter wall formed from a first extrusion of a first length of bare wire to create a first wire lead, a first co-extrusion of the wire and the zeolite; and a second extrusion of a second length of bare wire to create a second wire lead and at least one layer of zeolite wherein each layer having a perimeter wall and roads within the perimeter wall formed from an extrusion of the zeolite only.

12 . At least one adsorbent structure array formed from a continuous wire and zeolite, each array comprises:
a wire-embedded-zeolite layer having a perimeter wall and roads within the perimeter wall formed from a first extrusion of a first length of bare wire to create a first wire lead, a first co-extrusion of the wire and the zeolite; and a second extrusion of a second length of bare wire to create a second wire lead and at least one layer of zeolite wherein each layer having a perimeter wall and roads within the perimeter wall formed from an extrusion of the zeolite only.
