The NiO/γ-Al2O3 catalysts with different amounts of La2O3 and CeO2 were prepared with the same preparation method and under the same condition in order to compare the reaction performance (oxygen permeation, CH4 conversion, H2 and CO selectivity) on the membrane reactor. The results show that the oxygen permeation flux increased significantly with LiNiREOx/γ-Al2O3 (RE = La or Ce) catalysts by adding the element of rare earth especially the Ce during the POM in COG. Such as, the Li15wt%CeO29wt%NiO/γ-Al2O3 catalyst with an oxygen permeation flux of 24.71 ml·cm^-2·min^-1 and a high CH4 conversion was obtained in 875 ℃. The resulted high oxygen permeation flux may be due to the added Ce that inhibited the strong interaction between Ni and Al2O3 to form the NiAl2O4 phase. In addition, the introduction of Ce leads up to an important property of storing and releasing oxygen.展开更多

The mechanisms about solution desorp- tion after decarbonization were introduced briefly. Under the atmospheric pressure and in the presence of nitrogen carrier gas, several effects related to desorption of simulated decarbonization solution were analyzed, such as temperature, solution con- centration, pH, loading capacity, etc. The results showed that the CO2 desorption percentage increased with the increases of temperature, solution concentration and loading capacity, but CO2 desorption percentage increased with the increasing of pH and then decreased.展开更多
