Latest Patents
William E. Cormier's latest patents include two significant inventions. The first is titled "Novel Metal-Containing Zeolite Beta For NOx Reduction And Methods Of Making The Same." This invention discloses an organic-free, metal-containing zeolite Beta with a silica-to-alumina ratio (SAR) ranging from 5 to 20, and a metal content of at least 0.5 wt.%. The method of making this zeolite Beta does not require an organic structure directing agent (SDA). The metal, which may include Fe or Cu, can be present in amounts ranging from 1-10 wt.%. Additionally, a method for the selective catalytic reduction of nitrogen oxides in exhaust gases using the disclosed zeolite is also described.
The second patent is titled "Novel Microporous Crystalline Material Comprising A Molecular Sieve Or Zeolite Having An 8-Ring Pore Opening Structure And Methods Of Making And Using Same." This invention reveals a hydrothermally stable microporous crystalline material that includes a molecular sieve or zeolite with an 8-ring pore opening structure, such as SAPO-34 or aluminosilicate zeolite. This material is capable of retaining a specific percentage of its surface area and micropore volume after exposure to high temperatures and moisture, maintaining at least 80% of its surface area and micropore volume after treatment at temperatures up to 900°C in the presence of up to 10 volume percent water vapor for a duration of 1 to 16 hours. Methods for utilizing this crystalline material in the selective catalytic reduction of NOx in exhaust gas are also disclosed.
