METHOD FOR PRODUCING A SHAPED SINTERED POROUS BODY, BODY SO PRODUCED AND USES THEREOF

摘要

A shaped sintered fibrous porous body comprises inorganic fibers joined as a sintered structure and is produced by: dispersing and suspending a fiber mixture comprising inorganic fibers and organic binder, in a liquid to form a fibrous slurry; forming a body comprising the fiber mixture by depositing the slurry on a shaped screen to thereby shape the fibrous body; removing at least a part of the liquid from the fibrous body through the screen by a vacuum; drying the fibrous body heating the dried fibrous body to a first elevated temperature where the organic binder is removed from the body; subsequently heating the dried body to a second elevated temperature where the inorganic fibers are partly fused to form a sintered porous fibrous body. The body is suitable for use as or included in reactor elements to provide gas/condensed phase mass transfer areas in a system involving processing or treatment of gases and/or vapors through distillation, absorption and/or catalytic reactions.
