Analysis of pore size control and application of ceramic membrane based on particle sintering method

Ceramic membrane has been widely used in many fields. The pore size has an important effect on the separation effect of the membrane. Particle sintering is a mature method for preparing ceramic microfiltration membranes and has the advantages of convenient operation and strong controllability. In this study, the composite ceramic membranes with different pore size distributions were prepared. During the experiment, the influence of preparation conditions on the membrane was investigated, and the influence of inner coating and outer coating on the modification of the pore size was analyzed from the theoretical level. The carbon capture performance of the composite ceramic membrane was also tested. The experimental results show that the content of ZrO 2 has an effect on the structure of the film. When the solid content of the coating liquid is higher than 5 wt% and less than 20 wt%, and the sintering temperature is higher than 900 °C and less than 1300 °C, the formed film is complete without defects. Compared with the outer coating, the inner coating of the composite ceramic membrane has better applicability. In the carbon capture test, the CO 2 absorption efficiency can reach more than 90 %.
