| 20090029847 | Mesostructured material with a high aluminium content - A mesostructured material that consists of at least two elementary spherical particles, each of said particles comprising a mesostructured matrix based on aluminum oxide and having a pore size of between 1.5 and 30 nm, an aluminum oxide content that represents more than 46% by weight relative to the mass of said matrix, which has amorphous walls with a thickness of between 1 and 30 nm and whereby said elementary spherical particles have a maximum diameter of 10 μm, is described. Said mesostructured matrix can also contain silicon oxide. Each of the spherical particles of the mesostructured material can also contain zeolitic nanocrystals so as to form a material with a mixed porosity that is both mesostructured and zeolitic in nature. The preparation of said material is also described. | 01-29-2009 |
| 20090291837 | HONEYCOMB STRUCTURE - A honeycomb structure includes honeycomb units. Each of the honeycomb units has a longitudinal direction and includes inorganic particles, an inorganic binder, and cell walls defining cells extending along the longitudinal direction from one end face to another end face. The honeycomb units are bonded together via an adhesive such that each longitudinal direction is substantially in parallel. An amount of ammonia desorbed per unit mass of the honeycomb units is about 5 to about 100 times greater than an amount of ammonia desorbed per unit mass of the adhesive. The amount of ammonia desorbed per unit mass of the honeycomb units and the amount of ammonia desorbed per unit mass of the adhesive are measured by an NH | 11-26-2009 |
