- Abstract
Syngas methanation in a laboratory transport‐bed reactor has been performed. It was found that the CO conversion over the granular Ni/Al2O3 catalyst only slightly increased with the rise of aeration gas velocity for the recycling valve but severely decreased due to decreased gas residence time in the reactor. The effect of increasing the temperature of the recycled catalyst on the CO conversion at atmospheric pressure was also studied. Both the experimental temperature rise along the transport‐bed reactor and the estimated heat balance involving reactions verified the high heat‐transfer efficiency and its technical superiority for syngas methanation. The CO conversion in a laboratory transport‐bed reactor was tested to experimentally characterize syngas methanation to verify the feasibility of transport‐bed methanation. The CO conversion was found to be very high. The results of this study indicate the high heat‐transfer efficiency of particle recycling and the superiority of transport‐bed methanation over other techniques.
