Abstract:
A method for preparing a layered oxide cathode using a two step calcination procedure, wherein the first step includes pre-calcination utilizing a rotary calciner.
Abstract:
Provided are hydiOisomerization catalysts for processing a bio-based feedstock into biodiesel fuels. These catalysts comprise a catalytic material and a matrix component. The catalytic material is made up of a molecular sieve that has a pre-loaded platinum group metal. The catalytic material and the matrix component are processed together to form the hydroisomerization catalyst. Methods of malting these hydroisomerization catalysts include synthesizing a molecular sieve; purifying the molecular sieve; associating the molecular sieve with a platinum group metal in the absence of the matrix component to form the pre-loaded molecular sieve before formation of a catalyst body; mixing the pre-loaded molecular sieve with the matrix component to form a mixture; processing the mixture to form a catalyst body; and drying and calcining the catalyst body to form the hydroisomerization catalyst. These hydroisomerization catalysts can be used to process hydrodeoxygenated plant- or animal- derived feeds to yield a biofuel.
Abstract:
The hydroisomerization of a paraffinic hydrocarbon feedstock obtained from renewable sources is effectively achieved by passing the feedstock in the presence of hydrogen over a hydroisomerization catalyst comprising a crystalline metal silicate molecular sieve, in which a portion of the crystalline framework contains iron.

Abstract:
The present disclosure generally provides a catalyst composition comprising a zeolite containing iron and/or copper with a reduced amount of extra-framework aluminum. The catalyst composition is useful to catalyze the reduction of nitrogen oxides in exhaust gas in the presence of a reductant.

Abstract:
Se proporcionan catalizadores de hidroisomerización para procesar materias primas de base biológica en combustibles de biodisel. Estos catalizadores comprenden un material catalítico y un componente matriz. El material catalítico está compuesto por un tamiz molecular que tiene un metal del grupo platino precargado. El material catalítico y el componente matriz se procesan juntos para formar el catalizador de hidroisomerización. Los métodos para preparar estos catalizadores de hidroisomerización incluyen sintetizar un tamiz molecular; purifica el tamiz molecular; asociar el tamiz molecular con un material del grupo platino en ausencia del componente matiz para formar el tamiz molecular precargado antes de la formación del cuerpo catalizador; mezclar el tamiz molecular precargado con el componente matriz para formar una mezcla; procesar la mezcla para formar un cuerpo catalizador; y secar y calcinar el cuerpo catalizador para formar el catalizador de hidrisomerización. Estos catalizadores de hidroisomerización se pueden usar para procesar los alimentos derivados de animales o plantas hidrodesoxigenados para proporcionar un combustible biológico.
