Membrane apparatus for performing filtration, separation, or a catalytic reaction

摘要

Membrane apparatus for performing filtration, separation or a catalytic reaction, the apparatus including a macroporous block provided with parallel longitudinal through channels, the surface of each channel being covered with a respective membrane having finer pores than those of the block. According to the invention, the pores in both ends of said block are filled with a dense material (3) formed by a monometallic or polymetallic organic-inorganic polycondensate which has been subjected to heat treatment, this type of condensate being known under the name of ORMOSIL (organically modified silicate) or ORMOCER (organically modified ceramic).
