High performance inorganic hollow fiber membranes for hydrogen production with reaction-generated separation driving force

该项目致力于开发先进的膜，通过传输和反应过程的耦合来提高催化系统的性能。研究是用无定形二氧化硅膜进行的，这种无定形二氧化硅膜是通过将渗透选择性组分沉积在具有高氢渗透率和选择性的中间层的多孔氧化铝载体上而制备的。与填充床反应器(PBR)和膜反应器(MR)的对比研究表明，在所研究的所有压力下，MRS都能获得较高的转化率和氢摩尔流量。提出了一种工业应用所需磁导率的标准。

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.
