Abstract: A process for removing Pb2+ ions from fluids, such as gastrointestinal fluids is described. The process involves contacting gastrointestinal fluid with a particulate metal titanate ion exchanger represented by the empirical formula: AmTixMyOz where A is an exchangeable cation selected from the group consisting of potassium ion, sodium ion, lithium ion, calcium ion, magnesium ion, hydronium ion, and mixtures thereof, and M is optionally at least one framework metal selected from niobium (5+), zirconium (4+), tin (4+), iron (3+), iron (2+), cobalt (2+), and manganese (2+). The particulate metal titanate ion exchangers of the present disclosure are synthesized in the presence of complexing agents, including at least one multihydroxyl-containing complexing agent (MHCA), which facilitate metal transport and incorporation while imparting beneficial properties such as large aggregate size, well-behaved particle size distribution, and macroporosity.

Abstract: A process is provided for treating a stream comprising light olefins and carbon monoxide by passing the stream through a bed containing a copper containing material. The carbon monoxide needs to be removed in order to prevent poisoning of catalysts in downstream oligomerization reactors. This carbon containing material converts the carbon monoxide and hydrogen to carbon dioxide and water. The olefin stream is then dried and sent to an oligomerization step. There may be three beds so that the beds may alternate regeneration, reaction with CO and H2 and scavenging O2 steps.

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.

Abstract: A process is provided of treating a feed comprising polyethylene terephthalate comprising dissolving said feed in a polar solvent at a temperature between about 100 to 250° C. to produce a dissolved feed; then adding an anti-solvent that is less polar than said polar solvent followed by cooling a resulting mixture resulting in precipitation of purified polyethylene terephthalate and then separation of solid purified polyethylene terephthalate from remaining liquids.
