Study on characteristics of ceramic-based 3D printed catalyst supports used in methanol steam reforming for hydrogen production

Abstract 3D printing technology has the advantages of constructing ceramic-based catalyst supports with a complex three-dimensional(3D) flow field, outstanding thermostability and resistance to corrosion, which is suitable for methanol steam reforming (MSR). In order to master the chemical characteristics of ceramic-based 3D printed catalyst supports used in MSR, the mathematical models of reaction rate based on dynamic reaction partial pressure were established, and the accuracy of the model was verified by the experimental methods. The comparison between reaction rate models from the literature and the models derived from experiments was performed in detail. With the introduction of contact time and specific area of active component particles, a lower deviation of the mathematical models can be reached with a minimum of 10%. The model generated by 3D printing technology can be utilized for the high-precision design of ceramic-based 3D printed catalyst supports used for MSR.
