  • Publication number: 20180273463
    Abstract: Impure aromatic carboxylic acids such as are obtained by liquid phase oxidation of feed materials comprising aromatic compounds with substituent groups oxidizable to carboxylic acid groups, or comprising aromatic carboxylic acid and one or more aromatic carbonyl impurities that form hydrogenated species more soluble in aqueous solvents or with less color or color-forming tendencies than the aromatic carbonyl impurity, are purified to an aromatic carboxylic acid product with lower levels of impurities by a process comprising contacting an aqueous solution comprising the impure aromatic carboxylic acid with hydrogen at elevated temperature and pressure with an attrition-resistance, acid stable catalyst composition comprising at least one hydrogenation catalyst metal and a support comprising relatively high surface area of high porosity silicon carbide with low levels of iron and alkali metal impurities. The support may further contain titanium or rare earth metals.

  • Patent number: 9126184
    Abstract: A process is disclosed using a new catalyst for use in the alkylation of benzene with a substantially linear olefin. The catalyst allows for cation exchange with a rare earth element to increase the alkylation of benzene, while reducing the amount of isomerization of the alkyl group. This is important for increasing the quality of the alkylbenzene by increasing the linearity of the alkylbenzene.

  • Patent number: 8993467
    Abstract: A method of operating a continuous or semi-continuous system for a catalyst regeneration process. The system comprises a regenerator, the regenerator comprising a combustion zone and a halogenation zone. The catalyst is fed into the regenerator. A circulating regeneration gas is introduced into a regenerator circuit including oxygen, the circulating regeneration gas having a nitrogen concentration that is less than air. Oxygen from the circulating regeneration gas reacts with the coke to provide water and carbon dioxide. Water and the carbon dioxide formed in this first reaction then further react with the coke to form carbon monoxide and hydrogen.

  • Patent number: 8747807
    Abstract: A method for preparing a family of zeolites, examples of which have been designated UZM-5, UZM-5P and UZM-6, and are represented by the empirical formula Mmn+Cgh+Rrp+Al(1-x)ExSiyOz The method includes forming a Charge Density Mismatch (CDM) reaction mixture comprising reactive sources of Al, Si, optionally a framework element, E, and at least one organic nitrogen containing cation template, C, in the hydroxide form. After the CDM mixture is mixed while aging, an organic cation crystallization template, R, and at least one alkali metal or alkaline earth metal, M, is added. The combined final reaction mixture is reacted with mixing to produce the zeolite, which may be used in various hydrocarbon conversion processes.

  • Patent number: 7638667
    Abstract: Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8HS are described. The UZM-8HS zeolite are derived from UZM-8 zeolites by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8HS zeolites have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.
