Abstract: This work presents a route for the study on the absorption performance of gas into liquid under the condition of adding particles in a stirred constant temperature reactor. Two evaluated systems, hydrogen–water and hydrogen–methanol, with the addition of activated carbon particles (ACP) were carried out, respectively. The results showed that the addition of ACP into the water can enhance the mass transfer between hydrogen and water, the enhancement factor increases rapidly with the increase of the ACP content, and then tends to be unchanged. However, for the hydrogen–methanol system, ACP has little effect on the mass transfer performance. In addition, a gas–liquid mass transfer model considering the effect of solid particle enhancement was established based on the shuttle effect and two-film model. Results indicated that the predicted value agreed well with the experimental value in both hydrogen–methanol–ACP and hydrogen–water–ACP systems.
