Porous composite for heterogeneous catalysis
Abstract
A effect of the duration of mechanochemical activation process on morphology and particle size distribution of composite powder Cu-13 mass% Al has been investigated by quantitative stereological analysis. It has been found that intensive mechanical failure of particles and increased powder dispersion is directly related to the formation of brittle Cu9Al4 intermetal-lide. Hydraulic characteristics of porous elements for catalytic membranes obtained by hydration hardening of composite powder Cu-13 mass% Al in the form of an 80-100 μm thick layer on porous titanium discs have been investigated. It was established that the average pore size and permeability coefficient nonmonotonically depend on the particle size of the powder.
