As an important type of three-dimensional (3D) printing manufacturing, the digital lighting process (DLP) technology has attracted more attention in material formation due to its rapid prototyping and high precision. However, it is difficult to prepare a γ-Al2O3 structured catalyst carrier directly using this method. In this paper, a recipe of the light curing resin was proposed for the direct fabrication of the γ-Al2O3 structured catalyst carrier by employing DLP technology, and its characteristics of forming and sintering processes were analyzed. With this recipe, a γ-Al2O3 catalyst carrier with a complete structure and high precision was obtained. The characterization of the catalyst showed that the specific surface area of the formed γ-Al2O3 catalyst carrier was up to 163 m2/g, and X-ray diffraction (XRD) analysis showed that the main component was γ-Al2O3. Through a simple impregnation process, the experiment of methanol hydrogen production was carried out, and the catalytic performances of the 3D printing structure catalyst and activated alumina ball in the experiment of methanol hydrogen production were compared. The results show that the alumina catalyst support prepared by the DLP method exhibits excellent catalytic performance. This article has not yet been cited by other publications.
