Applied research on methane steam reforming properties of porous structural catalyst fabricated by selective laser melting technology

In this paper, structured catalysts with different specific surface areas were fabricated by selective laser melting (SLM), and their catalytic properties were tested by methane steam reforming experiments. The results show that the structured catalyst prepared by SLM shows high structural stability and catalytic activity with H2 yield of 51.44% and CH4 conversion of 71.94%. The structured catalyst prepared by SLM can be impregnated with the traditional catalyst, which can improve the catalytic efficiency. After impregnation, the H2 yield and CH4 conversion rate of structured catalyst can reach 71.98%, and 99.53%, respectively. Compared with the traditional catalyst, the methane conversion rate is significantly improved. This work provides a simple and efficient manufacturing method for the functional integration of catalyst and reactor, which will promote the development of chemical synthesis and SLM.
