Patent number: 7811964Abstract: A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.Type: GrantFiled: November 17, 2004Date of Patent: October 12, 2010Assignee: UOP LLCInventors: Leonid B.

Patent number: 7449597Abstract: A catalyst useful for carbonylation of olefins has been developed. The catalyst comprises a palladium compound, e.g. PdIm4Cl2, where Im is imidazole and HCl dissolved in water or an alcohol. Carbonylation using this catalyst involves contacting an olefin stream preferably in a solvent such as o-xylene with the catalyst and carbon monoxide at carbonylation conditions to provide a carboxylic acid or an ester. When the catalyst solvent is water one can obtain an acid as the product, but when the catalyst solvent is an alcohol one obtains an ester as the product.Type: GrantFiled: October 19, 2004Date of Patent: November 11, 2008Assignee: UOP LLCInventors: Irina Galperin, legal representative, Paul T.

Patent number: 6506510Abstract: A novel integrated system for the co-production of heat and electricity for residences or commercial buildings is based on the cracking of hydrocarbons to generate hydrogen for a fuel cell. Compared to prior art reforming methods for hydrogen production, the cracking reaction provides an input stream to the fuel cell that is essentially free of CO, a known poison to the anode catalyst in many fuel cell designs, such as PEM fuel cells. The cracking reaction is coupled with an air or steam regeneration cycle to reactivate that cracking catalyst for further use. This regeneration can provide a valuable source of heat or furnace fuel to the system. A novel control method for system adjusts the durations of the cracking and regeneration cycles to optimize the recovery of reaction heat.Type: GrantFiled: December 15, 2000Date of Patent: January 14, 2003Assignee: UOP LLCInventors: Daniel R.
