In this paper, an enclosed membrane‐photobioreactor was designed to remove CO 2 using Chlorella vulgaris . The performances of four reactors, which included the presented novel bioreactor, a draft tube airlift photobioreactor, a bubble column and a membrane contactor, were compared. The effects of the gas flow rate, light intensity, quality of the inner light source, and the characteristics of membrane module on CO 2 fixation were investigated. The results showed that the rate of CO 2 fixation in the membrane‐photobioreactor was 0.95–5.40 times higher than that in the other three conventional reactors under the optimal operating conditions
