A process for fabricating a structure of a zeolite-based paste with an intra-layer continuous wire embedded is disclosed. The structure is made of multiple layers stacked together, produced by an additive manufacturing (3D printing) process. Within this structure, at least one wire is embedded through a section of a layer or a layer in its entirety, where the wire comprises of both the encapsulated section within the structure and two bare wire leads protruding from the structure. The flowcharts for the overall process of the structure fabrication, as well as a flowchart for the specific process of fabricating the wire embedded layers is disclosed. The primary goal of this process is to fabricate a zeolite structure with an embedded, high resistance wire for uniform Joule heating for reduced power consumption and temperature ramp-up time during a desorption process.

Process for fabricating wire-embedded zeolite structures with bare wire leads

An apparatus for the extrusion of a solid wire into a resin or paste is disclosed. The apparatus consists of two main parts including an adapter for constraining the wire until mixing with the resin or paste ('wire injector'), and a motor-driven gear system that feeds the wire into the injector (‘wire extruder’). With this system, a bare wire can be extruded allowing for the creation of lead-in/lead-out sections, or for use with a resin or paste without an inherent curing, drying, or solidifying mechanism. Additionally, this apparatus allows for the extrusion of small (30-40 AWG) wires, enabling unique applications such as the injection of a resistive wire where smaller diameter wires are advantageous for minimized electrical or thermal overhead.
