Composição de material com estrutura porosa, métodos de preparação e usos correspondentes

摘要

The present invention relates to new materials and the preparation thereof, with a porous structure comprising calcium carbonate and magnesium carbonate of mineral origin or from algae or pieces of mollusc shells, formed mainly by said salt together with clays of the bentonite, ±-sepiolite and aluminium silicate type. It also relates to their industrial use in the removal of acid gases and vapours in fixed and mobile beds and to their use as agricultural fertilizers and for water treatment such as mineralization, etc. These materials are shaped like hollow cylinders of the smooth or ribbed, straight, curved, regular or irregular cut macaroni type and have a noticeable textural development in the form of structures of parallel channels along the longitudinal axis in a number greater than 2 and less than 100 channels per square centimetre cross section generally known as monolith or honeycomb.
