A filter for multiphase cleanup of gas streams, in particular flue gas streams, includes filter wall composites comprising a bulk macroporous support (40) having a microporous membrane (42) on one side and a chemically-active deposit (50) on the opposite side. The bulk macroporous support has a surface area of less than 5.0 m<2>/g, a compressive crush strength of between about 1.0 lb/mm to about 10.0 lb/mm, and a thickness of between about 1.0 mm to about 3.0 mm. The microporous membrane and the chemically active deposit have thicknesses of less than about 100.0 microns and less than about 10.0 mm, respectively. The process of multiphase cleanup of gas streams includes passing a gas stream, comprising particulate pollutants (16) and gaseous pollutants, through a filter having composite walls formed of a bulk macroporous support having a microporous membrane on one side, and a chemically-active deposit on the opposite side. |
