| Research Abstract |
This project deals with the development of advanced membranes for enhancing the performance of catalytic systems by coupling of transport and reaction processes. The studies were performed with amorphous silica membranes prepared by depositing the permselective components onto porous alumina supports with intermediate layers that have high hydrogen permeance and selectivity. Comparison studies with packed-bed reactor (PBR) and membrane reactor (MR) operation showed that higher conversions and hydrogen molar flows were obtained in the MRs for all pressures studied. A criterion for the required permeance for industrial applications is developed.
