ABSTRACT
STUDY OF SILICA MEMBRANE PERFORMANCE FOR SEPARATION HYDROGEN GAS FROM THE MIXTURE OF H2-H2O-HI TO SUPPORT EFFICIENCY OF HYDROGEN PRODUCTION. The membrane pores Sizing can be controlled by the value of time and CVD process. That's parameters were represented by the values of selected power of the (He/N2) gas. The membranes that have controlled their pores sizing by it's parameters were tested the power selected and permeation of H2 gas from the gaseous mixtures and singular system. Related on it's observation, the value of hydrogen permeation both in mixtures and singular have the similar value that are about of 10-7mol.Pa-1.s-1. This value was generated from the S3 membrane silica type where that membranes were stopped in modification at the value of power selection gas (He/N2) was 2,8. That's fact say that the best selectivity and permeation of H2 both in gas mixtures and singular are not generated from the smallest pore size but it was generated from the S3 membrane type which the selective power is 2.8. The permeation of H2 gas is relative same for all of type membrane and this reality was predicted because the size difference of He and N2 gas is relative higher so it is not very sensitive for looking on the best permeation of membrane. The propose of this study is to add the sophisticated knowledge in a silica membrane synthesis.
